How do you translate ISO 22095:2020 chain-of-custody documents without changing what a product claim actually promises? The difficulty lies in separating physical material, administrative records, sourcing characteristics, allocation rules and statements to buyers. A shipping document may describe a batch as segregated, a sustainability report may allocate mass-balance credits, and a certificate may identify a supplier. These are not interchangeable statements. A reliable translation keeps each claim attached to the precise model, evidence, quantity, period and product to which the source applies.
This practical guide is for translators, sourcing teams, assurance reviewers, importers, manufacturers and students who need to translate chain-of-custody certificates, mass-balance records, controlled-blending declarations, batch identifiers and product-facing claims. It explains the differences in ordinary language, offers fictional worked examples, shows where an apparently natural paraphrase becomes misleading, and gives a multilingual review process. It is not a substitute for the licensed ISO publication, an accredited audit, a certification programme or the legal rules governing consumer and environmental claims.
Quick answer: First identify whether the claim follows a specific physical item, a physically separated class of material, a measured blend, an accounting balance or a separate certificate. Next preserve the source’s model name, percentage or quantity, inventory boundary, time period, chain participants, claim qualifier and evidence reference. Finally have a competent reviewer test whether someone reading the translation could infer more physical content, origin or certification than the original records justify.
- Primary question: what does the chain-of-custody model allow the claim to mean?
- Do not translate mass balance as proof that each unit physically contains the claimed input.
- Keep product codes, claim periods, weights, quantities and allocation events intact.
- Mark uncertain supplier statements for verification rather than silently upgrading them.
- Review consumer-facing copy separately from internal inventory and audit records.
Scope, edition and the line this article does not cross
ISO 22095:2020 is titled Chain of custody — General terminology and models. The official ISO catalogue describes a framework for chain-of-custody design, common terminology and general requirements for models across materials and products. It explicitly warns that the existence of a chain-of-custody system alone does not establish a characteristic of the product. As of November 2026, the 2020 publication has an amendment issued in 2026, and a successor project is being developed. This page refers to the published 2020 framework and directs actual compliance decisions to the controlled edition and amendment in use by the organisation.
This is a specialist language guide rather than an alternative certification standard. The term certified in an invented example describes what its fictional document claims; it does not mean eduKateSG has assessed a real certificate. No sample paragraph below is an official ISO clause or actual third-party finding. The official ISO 22095 record is the authority for edition and scope. Product-specific schemes, regulators, contracts and assurance bodies may define further requirements that translators should not try to invent.
The central distinction: material flow is not always claim flow
Imagine a manufacturer buying a physical tonne of a raw material and a separate certificate connected to production elsewhere. Both are valuable pieces of information, but they are not the same kind of evidence. The first tells us something about what entered a factory. The second may tell us that a programme allocated a claim or credit under defined rules. Translating both as ‘made from the certified material’ destroys precisely the difference a buyer needs. The right first question is not which English phrase sounds best. It is which physical or administrative relationship the record actually documents.
ISO 22095 distinguishes identity preserved, segregated, controlled blending, mass balance, and book-and-claim approaches. Those labels are not five grades of virtue. They are different information models with different implications for material identity, mixing and accounting. When a supplier’s target-language brochure uses one model’s strong physical language while its certificate supports another, the translation has become a new, potentially misleading claim.
A working vocabulary for translators
Identity preserved
Meaning. Material of a stated characteristic is tied to a single specific source across the relevant chain; the reader may need to know exactly which source. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not turn a source-specific claim into the looser statement that material is merely certified, and do not assume the exact producer is known if its identity was redacted. Confirm the identifier of the single origin, the physical handling records and whether the finished lot still corresponds to that origin. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Segregated
Meaning. Material with the claimed characteristic remains physically separate from material without it, although supplies from more than one qualified source may be combined. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Avoid ‘single-origin’ unless the source really makes that stronger assertion; segregation protects a characteristic without necessarily preserving individual farm or mine identity. Match inbound lots, storage zones, processing logs, output batches and the exact characteristic being maintained. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Controlled blending
Meaning. Material with and without a specified characteristic is intentionally mixed under controlled criteria to yield a defined proportion in the output. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not replace a measured or specified fraction with ‘fully certified’, or silently present a site-wide percentage as the content of each batch. Preserve batch definition, blending calculation, input masses, output masses and the statement specifying which fraction the claim concerns. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Mass balance
Meaning. An accounting model reconciles eligible inputs and claimed outputs under a defined period and allocation method, even when the physical contents of an individual item cannot be inferred. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not use wording equivalent to ‘this individual product physically contains exactly this much’ when the claim is based on allocated attributes. Check inventory boundary, conversion factors, credit opening and closing balances, eligible purchases, allocations and the claim language. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Book and claim
Meaning. An administrative certificate or credit may be traded separately from the physical product flow according to a recognised programme’s rules. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Never translate a credit purchase as a guarantee that the delivered item came from the credited source, and do not call it physical traceability. Identify certificate or credit number, issuance and retirement status, registry, beneficiary and the actual scope of the supported claim. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Chain of custody
Meaning. The controlled sequence of participants, transfers and records through which material and associated information are carried. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. The ordinary phrase ‘who held the goods’ can be insufficient because transformations and allocation rules may matter as much as possession. Read the journey from initial claim-bearing input through transfer, processing, storage and final output, including breaks and reconciliations. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Claimed characteristic
Meaning. The precise attribute being asserted, such as a specified feedstock category, origin, sourcing method or percentage. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Calling something ‘sustainable’ is often much broader than the documented attribute and may create a claim with no evidential owner. Identify exactly which characteristic the source certificate, transaction statement and product label name. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Eligible input
Meaning. Material or transactions accepted within the specific programme and time boundary for a calculation or claim. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Eligible must not be translated as ‘already approved for every use’ or as proof of a final-product claim. Check supplier eligibility, programme criteria, receipt date, quantity, product family and suspension or expiry conditions. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Declared output
Meaning. A quantity of output to which a scheme-specific claim or allocation is attached. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. A declared output is not automatically equivalent to a physically segregated output or a product independently tested for composition. Reconcile the output amount with input and yield records, then inspect whether the wording describes physical or allocated content. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Reconciliation period
Meaning. The window over which inbound, outbound, accumulated and assigned quantities are counted. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. If a quarter is mistaken for a single day’s production, the resulting translation may imply precision that accounting never intended. Preserve exact calendar start and end dates, timezone when operationally material and the balance-carryover rules. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Conversion factor
Meaning. An agreed quantity relationship used when turning an input into a different product, such as mass of feedstock into finished output. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not substitute a production yield inferred from another facility or product; the official ledger may use a scheme-defined factor. Record source units, output units, physical or accounting basis, calculation version and approval of the factor. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Allocation
Meaning. A documented assignment of an eligible attribute or quantity to one or more outputs under programme rules. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Translate as assigning claims, not secretly as inserting material physically into a finished item. Check that the same quantity has not been allocated twice and that the recipient product is in the permitted scope. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Retirement or cancellation
Meaning. An administrative status that prevents further use or transfer of a certificate or credit in the relevant system. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Retired credits are not exhausted physical materials; translating cancellation as destruction of goods creates a false event. Verify registry status, date, unique credit reference and reason, then distinguish a corrected transaction from final retirement. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Traceable
Meaning. Able to follow a specified object or attribute through suitable recorded relationships, within a stated boundary. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Traceable does not by itself mean independent certification, full transparency, absence of fraud or verified sustainability. Identify exactly what can be traced and how far, then note whether the evidence ends at a supplier, process or certificate. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Verified
Meaning. A claim or record has undergone some specified checking by an identified actor and method. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not silently intensify an internal review into independent third-party certification or regulatory approval. Retain the verifier, version, evidence set, scope, date, limitations and any unresolved nonconformity. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Certificate scope
Meaning. The specific entities, products, facilities, periods and activities actually covered by a document. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. A logo or corporate certificate must not become a claim that every product produced anywhere by the group is certified. Check document number, listed site, validity dates, scheme, exceptions and whether a transaction document is also needed. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Chain participant
Meaning. A party that receives, holds, transforms, allocates, verifies or transfers relevant material or records. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Do not use manufacturer, trader, warehouse or auditor as interchangeable occupational titles; each role has different responsibilities. Map legal entity, facility and role; keep subcontractors and agents separate where the source does. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Claim qualifier
Meaning. A word or phrase that limits assertion, such as ‘up to’, ‘allocated’, ‘approximately’, ‘under this scheme’ or ‘for the reporting period’. In translation work, identify the precise referent before selecting a short equivalent. A term in the supplier’s programme may be defined more narrowly than its everyday dictionary sense, so an apparently natural synonym can carry a different legal or operational implication.
Risk and verification. Qualifiers are part of factual meaning, not optional advertising clutter; dropping one can upgrade a conditional claim into a promise. Compare front-label, catalogue, invoice and certificate wording and retain the least ambiguous faithful formulation. Where the record does not settle the point, label it as a query; do not make the target-language reader believe that a missing fact has been checked.
Worked translation casebook: fictional examples, real decision types
Case 1. Single farm versus several qualified farms
Fictional source. Source: ‘Lot R18 remains identity preserved from Source A; transport seal 7715 matched on receipt.’
Read the evidence. The origin claim is specific to a single source and to an intact documented chain. A later receiving team could reasonably expect source-specific traceability, not merely generic eligibility. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘The goods are certified and traceable.’ It drops Source A and the evidence of a physical seal, converting an origin-specific assertion into an untestable generality. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: translate ‘identity preserved’, Source A, lot R18 and seal 7715 verbatim as identifiers, with the original sequence of events. If the target language lacks the technical phrase, add a brief controlled explanatory term in the approved glossary. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: ask a warehouse reader to locate the same seal and lot in its records. Ask whether the new text still promises a single origin and whether any evidence supports the promised chain. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 2. Segregated warehouse space
Fictional source. Source: ‘Certified input from farms A and B stored in Zone S; no conventional input handled in this zone during the period.’
Read the evidence. The characteristic is preserved through separation, while exact single-farm identity may not survive pooling. Warehouse terminology has direct consequences for interpreting a goods-receipt note. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Single-origin certified stock.’ The noun phrase adds a source exclusivity claim not present in the inventory record. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: use ‘segregated’, retain Zone S and the interval, and explain that the materials came from two eligible sources if the target-market audience might otherwise read ‘segregated’ as single-origin. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: compare the target text with intake records and warehouse plans; distinguish a permanent zone policy from the conditions proven for this period. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 3. Two-input controlled blend
Fictional source. Source: ‘Batch B7 contains 60% qualifying input and 40% other input by recorded mass.’
Read the evidence. This is a batch-content assertion based on a controlled mixing operation, unlike a free-floating site allocation. The number describes the blended output only if the source record supports that basis. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘60% environmentally friendly product.’ That replaces a specified qualifying characteristic with an undefined environmental judgement. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: keep 60%, 40%, ‘by mass’, Batch B7 and the exact characteristic name. Retain calculation references and any measurement uncertainty or rounding explanation. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: verify the denominator, the source unit and whether losses, moisture or additives were included. Do not calculate a new percentage inside the translation. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 4. Mass-balance polymer claim
Fictional source. Source: ‘120 tonnes of eligible feedstock were allocated to product family F under the site’s mass-balance rules for Q2.’
Read the evidence. The ledger concerns quantities and a period. It does not establish the exact molecular contents of each unit of product F. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Every pack of F contains eligible feedstock.’ That turns an administrative balance into physical item composition. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: translate as ‘eligible feedstock attributed through a mass-balance system’ and preserve 120 tonnes, product family F and Q2. Use the scheme-approved wording for packaging claims. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: inspect opening balance, purchase entries, output allocations and whether family F is authorised. Test what a buyer might infer from the translated label. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 5. Credit divorced from delivered shipment
Fictional source. Source: ‘Certificate C-42 retired on behalf of buyer M; shipping lot 318 supplied through conventional route.’
Read the evidence. The credit represents an administrative claim with a separate chain from the physical shipment. The sentence deliberately states both facts. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Buyer M received certified material with lot 318.’ That contradicts the record’s description of the physical shipment. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: name the retired certificate and separately describe the conventional delivery. If the programme permits an exact market claim, retain its approved language without adding a physical-origin promise. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: check registry status, retirement date, beneficiary and goods documentation. Request specialist confirmation where promotional copy attempts to fuse these separate chains. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 6. Quarterly versus monthly inventory
Fictional source. Source: ‘Opening balance 80 t, eligible purchases 50 t, claims allocated 90 t, carry-forward 40 t; quarter ending 30 June.’
Read the evidence. The arithmetic in this fictional ledger is internally coherent: 80 + 50 – 90 = 40 tonnes. It becomes misleading if the dates or ledger concept change. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Monthly consumption 90 tonnes; remaining stock 40 tonnes.’ It confuses claim allocation with physical consumption and a quarter with a month. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: label each quantity by its accounting role and retain ‘quarter ending 30 June’ without inferring day-by-day material availability. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: recalculate the equation independently, verify units and separate stock physical balance from eligible-attribute balance. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 7. Two facilities and one brand
Fictional source. Source: ‘Facility North certified for processing; Facility South outside current certificate scope.’
Read the evidence. The legal name of a brand may appear on both products, but the certificate’s geographical and operational boundaries are narrower. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘All brand products meet the programme.’ That enlarges certification across facilities without evidence. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: preserve named site and certified activity. Keep explicit exclusion for Facility South and flag marketing phrases that omit the limitation. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: compare scope annexes, expiry date, invoice source and packing-site ID. A translator should not issue an assurance decision, but can prevent an unsupported one being introduced. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 8. Receipt date after a suspension
Fictional source. Source: ‘Supplier approval suspended from 9 May; batch accepted 6 May, received 11 May, eligibility review pending.’
Read the evidence. The dates distinguish contract acceptance, physical receipt and an unresolved eligibility decision. The record does not settle whether credits can be recognised. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Approved supply received 11 May.’ It deletes the suspension and the word pending. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: retain three separate states and make the unresolved status visible in the target text rather than converting chronological sequence into compliance approval. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: seek programme owner clarification for the applicable date rule and preserve the answer as a controlled change note. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 9. Negative adjustment after return
Fictional source. Source: ‘Return RT9 reversed prior allocation of 14.5 kg; no replacement claim issued.’
Read the evidence. The ledger records an accounting reversal. It does not say 14.5 kg of goods were destroyed or that a substitute item received the attribute. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘14.5 kg of certified product was discarded and replaced.’ Both the disposal and replacement are invented. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: translate reversal, allocation and no replacement claim as separate events. Keep sign convention and decimal precision. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: trace RT9 to the original allocation; ensure exported reports and client letters do not turn a correction into a newly created credit. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 10. Weight in wet tonnes versus dry tonnes
Fictional source. Source: ‘Input declared 34.0 t as received; dry-basis equivalent 31.6 t used for reconciliation.’
Read the evidence. The two weights describe the same material under different measurement bases. They cannot be swapped just because both use tonnes. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Input was 34 tonnes of qualifying dry material.’ That makes the reported quantity larger and hides the moisture adjustment. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: keep ‘as received’, ‘dry-basis equivalent’ and both values with matching units. If the source does not state a methodology, do not invent one. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: check moisture factor, rounding and whether a claim is based on the 31.6 t figure or another approved quantity. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 11. Transport ownership transfer
Fictional source. Source: ‘Legal title passed on loading; physical custody passed to carrier at gate 4; records transferred electronically next day.’
Read the evidence. Title, possession and administrative data transfer happened at different times. A multilingual handover contract must not merge them. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘The buyer took possession of all documents on loading.’ That changes both the actor and the event. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: retain title, custody and records as three separate concepts, keeping gate 4 and the next-day electronic transfer. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: trace each statement against the legal and transport records. Escalate legal wording rather than substituting colloquial synonyms. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 12. Consumer label without model disclosed
Fictional source. Source: ‘Made with responsibly sourced inputs’ beside a mass-balance certificate whose approved claim uses an allocation qualifier.
Read the evidence. The invented marketing line may already be broader than the supporting document. A translator should detect this, not silently make it still broader. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘This product contains only responsibly sourced material.’ The phrase adds total physical composition and absolute exclusivity. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: raise a claim-approval query and use controlled programme wording only after the owner confirms it; record that the source copy itself required review. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: compare packaging space, footnote legibility, consumer inference, certification permissions and whether each market has its own advertising obligations. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 13. Credit double counting
Fictional source. Source: ‘Allocation A14 entered to buyer P; second invoice proposed same 8 t without ledger reversal.’
Read the evidence. Two invoices referencing one attribute balance can create a double-counting concern. The translator must keep the status ‘proposed’ and not invent a correction. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Eight tonnes certified for each buyer.’ This wrongly suggests a second allocation is already authorised. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: make proposed and entered different states, preserve A14 and the original buyer, and flag the duplicate reference as an unresolved review matter. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: reconcile the relevant balance after a documented corrective entry. Do not release external claims until the responsible party clears the ambiguity. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
Case 14. Mixing method changed midyear
Fictional source. Source: ‘January–June: physical segregation; July onward: mass-balance allocation after process conversion.’
Read the evidence. The same product name covers two periods with different claim mechanisms. A translator cannot borrow January’s strong physical language for August’s output. The first question is what this sentence demonstrates, not which English synonym sounds smooth. Identify the material, accounting entry, participant and interval before deciding what can safely be said in another language.
A plausible but unsafe version. Weak translation: ‘Segregated material throughout the reporting year.’ That erases the change point and contradicts the later model. This would cause a reader to act on a stronger or different claim, even if every individual word looked familiar.
A faithful translation decision. Better: preserve both intervals, method labels and effective date. Where a brochure covers the entire year, use a statement that accurately distinguishes the periods. Good technical translation is explanatory where the audience needs clarity but conservative about facts that have not been established.
Proof before release. Review: test early and late batch IDs separately, and record which version of the customer-facing claim applies to each production window. A second bilingual reviewer should compare the revised statement with the original sentence and actual record field, not merely with another translated summary.
A twelve-stage multilingual review workflow
1. Identify audience and destination
Is the target reader a production planner, auditor, customs officer, investor or consumer? Ask what decision the words will drive. A ledger note can tolerate codes with a glossary; a consumer label needs simple but controlled phrasing. Do not make the label’s apparent certainty stronger merely because it has less room. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
2. Freeze edition and scheme
Record ISO 22095:2020, its applicable 2026 amendment, and the exact industry programme or customer requirement. A broad ISO reference does not certify a claim by itself. Preserve source version and approval date so reviewers know which vocabulary and model were being used. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
3. Build a claim map
For each statement, write the claimed attribute, physical or book relationship, source lot, holder, time window, quantity and evidence number. If one field is unknown, mark it unknown. A source sentence can mix verified facts and supplier aspirations; the map prevents them from blurring. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
4. Label the model
Choose identity preserved, segregated, controlled blending, mass balance or book and claim only when the source and scheme establish that choice. Never infer the model from a marketing adjective, and do not rename a hybrid arrangement without a decision from the programme owner. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
5. Lock protected identifiers
Do not translate batch numbers, source codes, product grades, certificate IDs, registry URLs, dates in machine-readable fields or document revision IDs. Handle spaces and separators according to the receiving system’s specification, not the translator’s stylistic preference. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
6. Preserve quantity mathematics
Record tonnes, kilograms, wet and dry bases, fractions, yield factors and credit periods. Check whether percentages refer to physical content, input eligibility or attribute allocations. Recompute fictional arithmetic in a separate review sheet without replacing controlled source values. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
7. Preserve modality and uncertainty
Distinguish ‘may’, ‘shall’, ‘approved’, ‘eligible’, ‘pending’, ‘verified’, ‘proposed’ and ‘subject to’. The translator must not convert recommendations into mandates or conditions into facts. Ask the issuer to resolve actual ambiguities. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
8. Check negative and excluded statements
Words such as ‘not’, ‘except’, ‘outside’, ‘no replacement’ and ‘not within scope’ often carry more decision weight than the headline claim. Read each in a standalone target-language sentence and check that exclusions remain visually accessible. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
9. Compare evidence boundaries
Separate a document certifying an organisation, a facility, a product line, a transaction and a credit. Reconcile names and scopes between the certificate, invoice and published marketing claim. An elegant translation is unusable when its evidence points at the wrong entity. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
10. Review for consumer inference
Give the draft to a person not involved in production. Ask what material they think is physically in the item, where it came from, and whether the claim was independently checked. If their answer exceeds the source’s evidence, revise or escalate. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
11. Log questions and corrections
Keep a query ledger with source excerpt, uncertainty, owner, answer, approval date and revision. Distinguish a translation correction from a change to the underlying ledger or marketing statement. Never quietly alter the source to make the target sentence look consistent. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
12. Approve and archive
Record reviewer roles, release version, approved claim glossary and links to evidence. Ensure the same wording reaches packaging, web pages, technical documents and translations. If the source claim changes, trigger a fresh review rather than assuming prior approval transfers. A usable deliverable at this stage is a short recorded decision: what was checked, which source proves it, and what the next reviewer must not assume. This discipline prevents a polished translation from becoming an untraceable claim of its own.
Common questions
Is mass balance the same as segregation?
No. Segregation is about physical separation of material meeting a specified characteristic. Mass balance allows an accounting relationship under stated rules and may not establish what portion of one individual product physically contains eligible material. Keep the distinctions visible. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Does ISO 22095 certify a product?
No. ISO’s public description says the chain-of-custody framework alone cannot substantiate product characteristics. A particular claim needs its own evidence, programme rules and applicable verification. A translator should not imply that citing a standard equals certification. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Can a translator rewrite a marketing claim to make it clearer?
Clearer wording is appropriate only while the original meaning is preserved. If a source sentence appears unsupported, a claim owner must approve a correction. The language team should flag the issue and document the resolved version, not invent stronger credentials. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Should the original model terms remain in English?
That depends on the market, contract and programme. An approved bilingual glossary may pair a translated term with English on first use. Keep a stable concept definition; the reader must be able to match the term to the official scheme and its supporting records. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
How do we translate book-and-claim credits?
Describe the certificate or claim allocation and its administrative status. Do not imply a direct physical connection between the credited source and a delivered shipment unless separate records establish it. Check issuance, holder, transfer and retirement information. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
What happens when two language versions use different percentages?
Treat it as a control failure until reconciled. Verify denominators, basis, periods, decimal separators, rounding and whether each number measures physical content or an attributed quantity. Do not average the two figures to hide the inconsistency. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Can we call a supplier ‘fully traceable’?
Only if the statement has a defined scope and evidence supports the extent of traceability claimed. It may be more accurate to say a particular lot, location, custody step or certificate can be traced. Absolute language needs exceptional care. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Why not simply use AI translation?
Software can suggest vocabulary and maintain a glossary, but it cannot approve an unverified sourcing claim or substitute for record reconciliation. Use tools as drafting and comparison aids, then have authorised people check model type, quantities, evidence and market language. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Does a 2026 amendment change this page’s examples?
The official ISO catalogue lists an amendment to the 2020 edition. Organisations should confirm the controlled text and its applicability before working to a contract or conformity assessment. These examples teach translation decisions, not a representation of every amendment clause. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
What if the source itself is ambiguous?
Record the exact ambiguous phrase, plausible interpretations and the decision it could change. Ask the source owner or technical reviewer to resolve it, then preserve the answer and version in the translation log. An unsupported guess should never become a product claim. For release, keep the decision traceable to a named source and a reviewer who understands the relevant model; that matters more than finding a catchy synonym.
Practice exercises for teams and students
The disappearing qualifier
A brochure says ‘materials attributed under a mass-balance programme’. Translate it into two hypothetical languages and compare with a back-translation. Is the word attributed still present? Would a consumer assume all delivered molecules have the claimed origin? Document the exact phrase that prevents that inference. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
Three sites, one certificate
Create fictional documents for two covered facilities and one uncovered warehouse. Write one certificate-scope statement per location. Ask a second person to identify which location can legitimately be named. Revise any sentence that transfers certification by brand association. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
A balance with a changed denominator
Give a learner 75 t of eligible input, 60 t allocated and 15 t remaining, then add a dry-mass conversion note. Ask for a translation that preserves both source figures and calculation basis without presenting the adjustment as additional material. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
One physical batch, two administrative claims
Create an imagined record whose water attribute uses mass balance while a particular ingredient remains segregated. Translate both sentences and ask whether the audience could confuse the models. This exposes why the model belongs to a particular claim, not merely to a whole factory. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
A period boundary
Compare a 30 June cutoff with a July 1 issuance and a late-posted invoice. Practice wording that labels the transaction date, claim period and posting date separately. Do not resolve eligibility just by translating the newest date as a sign of approval. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
An intentionally unsupported promise
Draft a hypothetical statement: ‘All products are guaranteed responsibly sourced’ with only a limited facility certificate as evidence. Train reviewers to write a query rather than a prettier promise. The correction path is source-owner approval, not creative translation. A productive debrief asks which exact word would change a purchasing, assurance or manufacturing decision, which record can answer that uncertainty and what a truthful final sentence would allow the reader to conclude.
Official reference and connected learning routes
Official edition and scope: ISO 22095:2020 — Chain of custody: General terminology and models. For the overarching discipline of cross-language meaning and evidence, continue to Master Art of Translation — the existing complete system. For word meaning and retrieval rather than supply-chain claims, use the Vocabulary Learning Hub. For how English structure communicates scope, qualifiers and purpose, continue to How English Works. This specialist page owns only translating chain-of-custody records and claims; it is not a competing broad guide.
The final test is practical: ask whether an international buyer could distinguish exactly what is physically present, what is allocated in records, what a certificate verifies and what remains unknown. If that distinction survives the translation, the language has preserved the one thing a chain-of-custody document cannot afford to lose: the boundary of the claim.
