Verifying a certification claim, and specifying one in an enquiry
Verification is a short sequence and most of it takes minutes. The reason it so often goes undone is not difficulty but timing: it is treated as a compliance check near shipment rather than as a sourcing question at enquiry, by which point the fabric is bought and the answer is expensive.
Contents
Two tasks live on this page. One is what to do when a supplier makes a certification claim. The other, which prevents much of the first, is how to write the requirement into an enquiry so that the documentation arrives alongside the price instead of six weeks later.
When a claim arrives
The sequence below works across schemes, but the detail at each step is scheme-specific and the differences matter. What a claim rests on under a chain-of-custody standard is not what it rests on under a product-testing certification.
- Identify the scheme precisely. "Certified" and "sustainable" are not schemes. A named standard is the minimum starting point, because everything after this step depends on which system you are in.
- Identify the organisation. Certificates belong to legal entities. Check that the certified organisation is the one you would be contracting with, rather than a parent, an affiliate or a mill the supplier buys from.
- Check the certificate against the scheme's own records. A supplied document shows what was true when it was issued. Schemes maintain records that can be checked directly, and that is the check that counts.
- Read the scope. Which processes, and which product categories. A certificate covering one process does not cover another, and this is where an otherwise valid document stops supporting a particular offer.
- Match it to the actual material. The quality, composition and construction you are being quoted have to sit inside that scope.
- Establish the transaction-level position. For a chain-of-custody claim, ask whether documentation will be issued for the delivery, as covered in scope and transaction certificates.
- Work out where certification stops. If the manufacturing step is outside the certified chain, decide now what claim remains available for the finished product.
- Check what the scheme's claims rules allow you to say, which is a separate question from whether the product qualifies.
Where the official records are
Each scheme publishes its own verification route, and using it is faster than assessing a document by eye.
| Scheme | Route |
|---|---|
| GOTS | A public database of certified suppliers, published by the standard owner at global-standard.org |
| OEKO-TEX | Label Check: scan the QR code on a label or enter the certificate number at oeko-tex.com |
| Textile Exchange standards | Current standard documents, transition policy and assurance information at textileexchange.org |
Check the scheme's own source rather than a copy hosted anywhere else, including here. Records change, and a certificate that was valid when a supplier profile was written may not be valid when you are buying.
Where a scheme exposes a status beyond simply valid or expired, that status is worth reading rather than skimming. Not every scheme publishes the same states, so interpret what a given system actually shows instead of assuming a common vocabulary across all of them.
Specifying it in an enquiry
The efficient version of all of this is to ask for it up front. A certified-material requirement changes which fabrics can be offered, and therefore price, minimum quantity and lead time, so it belongs with the specification rather than after it. The general shape of a usable enquiry is covered in the RFQ guide; these are the lines that a certification requirement adds.
Certification lines in an enquiry
- The standard required, named specifically
- The fibre or material the requirement applies to
- The minimum certified content, as a number rather than a description
- The claim you intend to make on the finished product, in the words you intend to use
- Whether the manufacturing step has to sit inside the certified chain
- Whether transaction-level documentation is required for the delivery
- Which markets the product is sold into
- Any labelling or on-product wording the claim will appear in
- The usual specification alongside it: composition, weight, construction, colour, product, quantity and timing
The fourth line does much of the work. A supplier can tell you what is achievable far more usefully when they know what sentence the product has to support, and a requirement expressed as a claim rather than as a certificate name tends to produce a better answer.
What to ask for, by scheme type
The documentation request differs depending on what kind of certification is involved, and asking for the wrong thing wastes a round of correspondence.
Two different asks
Chain-of-custody schemes
- The certified organisation's identity and its certification body
- The certificate identifier that lets you search the scheme's records
- The certified scope: processes and product categories
- Validity dates
- Whether transaction documentation will be issued for the order
- Where certification stops in the route from fibre to finished garment
Product-testing certification
- The certificate number, to check against the scheme's own label check
- The certified organisation
- The product class, matched to how your product is worn
- Which articles and components are covered
- Validity dates
The right-hand column is short because product certification answers a narrower question, which is exactly the point made in OEKO-TEX STANDARD 100. Asking a product-testing scheme for chain-of-custody evidence, or the reverse, is a common way a documentation request goes nowhere.
When the answer is that the claim is not available
Sometimes verification establishes that the claim a brand wanted cannot be supported: the manufacturing step is outside the chain, the content threshold is not reached, or the documentation route does not exist for that material. That is a useful outcome rather than a failure, provided it arrives early.
The options at that point are ordinary sourcing decisions. Change the material to one where the chain is complete. Move the production step inside a certified chain, which narrows the factory options and changes the cost. Reduce the claim to what the evidence supports. Or accept an uncertified material and make no claim at all, which is a legitimate answer and a better one than a claim that cannot be substantiated.
The reason to run this at enquiry stage rather than at shipment is that all four options stay open while the fabric is still a proposal, and only the last two remain once it has been bought.
Questions this raises
How do I verify a supplier's textile certificate?
Identify the scheme, identify the certified organisation, then check it against the scheme's own records rather than the document you were sent. GOTS publishes a database of certified suppliers and OEKO-TEX provides Label Check for certificate numbers and label QR codes. Then read the scope and confirm the material you are buying sits inside it.
What should I put in an RFQ if I need certified material?
Name the standard, the material it applies to and the minimum certified content as a number, then state the claim you intend to make on the finished product. Add whether the manufacturing step has to be inside the certified chain, whether transaction-level documentation is required, and which markets the product sells into. The claim is the most useful line, because it tells a supplier what the evidence has to support.
The supplier sent a certificate. Is that enough?
It is a start. Confirm it is current against the scheme's records, that the certified organisation is the entity you would contract with, and that the scope covers the process and product category involved. For a chain-of-custody claim, also establish whether documentation will be issued for the specific delivery.
What if verification shows the claim cannot be supported?
Change the material, move the production step inside a certified chain, reduce the claim to what the evidence supports, or proceed without a claim. All four are legitimate. The problem is not discovering this; it is discovering it after bulk fabric has been committed.
Put the claim in the enquiry
Tell us the standard, the content, the product and the sentence you need to be able to write. That is enough for us to confirm what can be sourced and what documentation travels with it.
