How Do You Prove Recycled Content — Certification or Transaction Certificate?

What Is the Difference Between GRS Certification and a Transaction Certificate?

These two documents are confused constantly, and the confusion is where most false recycled claims come from. A scope certificate is issued to a company for a site. It says that the site was audited, that it is entitled to trade in certified material, and it lists the product categories and the processes it is certified for. It says nothing whatsoever about any particular shipment. A transaction certificate is issued for one transaction between two certified parties, and it is the document that carries the recycled content claim from the seller to the buyer.

The practical consequence is blunt: a supplier showing you a scope certificate has shown you a licence to operate, not evidence about your goods. You can hold a current scope certificate and ship a container of conventional fabric, and the scope certificate will not contradict you. Only a transaction certificate tied to that shipment, that quantity and that product description does that. When a buyer asks for "the GRS certificate" and accepts a scope certificate in reply, the claim is unevidenced from that moment.

The standard itself is worth one sentence of orientation. The Global Recycled Standard is owned and administered by Textile Exchange, and it sets requirements for recycled content, chain of custody, social and environmental practice, and labelling. Certification is carried out by approved certification bodies rather than by the standard owner, which is why a TC always names the body that issued it and why that name is one of the things you check.

Who Issues a Transaction Certificate, and Who Is Allowed to Request One?

The seller requests it, from the certification body that certified the seller. Not the buyer, and not the brand at the end of the chain. This trips people up constantly: a brand asks its bag supplier for a TC, the bag supplier has to ask the fabric mill for a TC on the fabric shipment, and the mill has to ask its own certification body. Each step in the chain produces its own TC, and each one is requested by the seller in that step. If the document you are holding was requested by anybody other than the seller named on it, something is wrong.

Both parties in the transaction have to be certified for a TC to be issued. A supplier buying recycled fabric from a certified mill does not receive a TC if the supplier itself is not certified, because the chain of custody would break at that point. This is the single most common structural failure in bag programmes: the fabric mill is certified, the bag supplier is not, and no TC can exist for the fabric-to-bag step. The buyer at the end of that chain has a mill certificate and no chain.

The practical rule for a brand is to ask two questions at the quotation stage rather than at the shipping stage. Is your site certified, and can you show the current scope certificate. Will you request a TC naming our entity as the buyer for this shipment. The second question is the one that matters, because a supplier who cannot answer yes cannot deliver a documented claim however good the material is.

Which Fields Must Appear on a Transaction Certificate?

A TC is a form with a fixed field set, and the field set is what makes it checkable. The document is not a narrative; it is a reconciliation between a commercial invoice, a packing list and a claim. Below is the field set to check against, and what a mismatch in each field actually means when you find one.

The weight field deserves particular attention because it is where honest suppliers and dishonest ones part company. A TC covers a stated quantity. If you bought 800 kilograms of recycled fabric and the TC covers 500 kilograms, then 300 kilograms of your order carries no claim, and any product made from that 300 cannot be described as recycled. This is not usually deception; it is partial coverage being presented as full coverage. Check the arithmetic before you print anything.

How Is Recycled Content Calculated Across a Supply Chain?

The percentage is a weight calculation, and the denominator is where programmes go wrong. The certified recycled input is weighed, the total product is weighed, and the percentage is the first divided by the second. That sounds trivial and it is not, because a bag is an assembly of textile and non-textile parts and the treatment of the non-textile parts decides the number. Confirm the denominator with the certifying body for your specific product, because this is exactly where a claim gets challenged.

Note what that example does to a product page. The shell is 100% certified recycled polyester and the finished bag is 45.2% recycled. Both statements are true and they are not interchangeable. "Made with recycled polyester" is defensible. "Recycled bag" is not, and "100% recycled" is false. The gap between the true number and the flattering number is where regulators and platform compliance teams do their work.

The second calculation is the one the certification body runs on the supplier, and it is worth knowing because it is what makes the number auditable. It is a mass balance: certified inputs received, minus certified outputs shipped, minus recorded waste, should reconcile within a tolerance. If a mill buys in 10 tonnes of certified recycled fibre and ships 14 tonnes of certified recycled fabric, the books do not balance and no honest TC can be issued for the difference. That reconciliation, not any test on the finished fabric, is what chain of custody means.

How Do You Request a TC From Your Supplier, Step by Step?

The request has to be made before the goods ship, because a TC is issued against a transaction and the transaction has a date on it. Making the request after the container has gone is the most common reason a programme ends up with good material and no document. Below is the sequence, and the timing that matters is in step two.

1. Confirm both parties are certified. Ask for the current scope certificates of your supplier and of the mill above it, and check that the product categories listed actually cover what you are buying.
2. Put the TC requirement in the purchase order. Name it as a condition of the shipment documents, alongside the commercial invoice and the packing list, before production starts.
3. Fix the product description early. The description on the TC has to match the commercial invoice line. Agree the wording when the order is placed, not when the TC is issued.
4. Ask for the pre-consumer and post-consumer split. A single percentage is incomplete. Get the split in writing at the quotation stage so the TC can be checked against it.
5. Request the TC at shipment, against the transport documents. The seller applies to its certification body with the invoice, the packing list and the bill of lading reference.
6. Receive the TC and reconcile it. Match the seller, the buyer, the product, the weight and the transport reference against your own documents, field by field.
7. File the TC against the lot record. Store it with the dye-lot number and the inspection report for that shipment, so a later claim can be answered in minutes.

Step seven is not administrative tidiness. A TC that is not filed against a lot is a TC you cannot find when a marketplace or a regulator asks, and the question always arrives months later. The same folder discipline that makes the fifth reorder verifiable is what makes a recycled claim defensible: one lot, one document set, one place to look.

Timing sits inside the production calendar rather than after it. The document set is prepared in the booking window at the end of the 35-50 day bulk schedule, alongside the invoice, the packing list and the papers for customs entry. Ask for the TC at that point and it arrives with the rest of the set. Ask for it after the vessel sails and you are chasing a document across three time zones with a deadline nobody owns.

How Do You Verify a TC Is Real Rather Than a Template?

Verification is a reconciliation, not a phone call. The document is checked against three other documents you already hold — the commercial invoice, the packing list and the bill of lading — and against two facts you can establish independently — that the issuing body is approved for the standard, and that both licence numbers belong to live scope certificates. Every one of those checks takes minutes and none of them requires access to anything proprietary.

One field deserves its own warning because it is the easiest to fake and the least often checked: the buyer name. A TC naming a different company as buyer is a valid TC for a transaction you were not part of. It proves that recycled material moved between two other parties. It does not prove anything about the goods in your warehouse, and a surprising number of "certificate packs" supplied to brands consist of exactly this.

What Are the Common Ways Recycled Claims and TCs Are Faked?

Most false recycled claims are not forged documents. They are real documents used outside the scope they cover, which is why they survive a casual check and fail a careful one. The list below is what to look for, in rough order of how often it turns up.

How Should Recycled Content Be Worded on a Page or a Hangtag?

The rule is that the claim must be specific, quantified, and traceable to a document you hold. Every regulator that has written on environmental claims, from the FTC Green Guides in the United States to the European rules on unfair commercial practices, converges on the same three tests, and the self-declared claim standard ISO 14021 is built on them. A claim that fails any one of the three is the claim that gets challenged.

Two more rules finish the set. Do not state a number higher than your lowest-verified component: if a colourway uses a different shell with less recycled content, that colourway carries its own number and its own TC. And do not let the claim outlive the document: a TC covers one transaction, so a claim on a product page should be tied to the lots that TC covered, or re-verified when the next lot arrives.

Does the Finished Bag Fall Inside the Certified Scope?

Chain of custody runs along the trading chain, not along the product alone, so the answer depends on which link you are standing on. The mill that produces the recycled fabric is certified for that process. The assembly operation that cuts and sews the bag needs its own certification to pass the claim along to you, because it is a separate party performing a separate process. When both links are certified and each transaction has a TC, the recycled content claim travels from the fibre to the finished bag. When either link is missing, the claim stops there.

The fabric is where the recycled content physically lives, and it is the input that carries the percentage. Non-textile components — hardware, foam, stiffener, and most coatings — sit outside the recycled content calculation in the sense that they contain no recycled input, but they sit inside the denominator when the percentage is worked out over the whole product. That is why a bag with a fully recycled shell lands at 45% rather than at 100%, and why the denominator is worth agreeing in writing with the certifying body before anyone designs a hangtag.

There is also a threshold question that belongs at the design stage rather than the marketing stage. A product has to meet a minimum recycled content to be certified under the standard at all, and the mark carries its own threshold and its own licence, set by the standard owner. Those numbers are in the current standard and the current logo use policy, and they should be read from those documents rather than from a supplier summary. Ask for the policy reference with the quotation.

What Happens When the Bag Contains Non-Certified Components?

Nothing breaks, provided the arithmetic is honest. Certification does not require every component to be recycled; it requires the claim to be accurate and the chain of custody to hold for whatever recycled content there is. A bag with a recycled shell and a conventional lining can carry a valid claim, and the claim states the percentage the bag actually has. What it cannot do is describe the whole bag as recycled.

• Declare the composition honestly. List each component with its share and its recycled share, and let the percentage fall where it falls.
• Keep the certified and the conventional streams separate in production. Material of different status should be identifiable in the store, because a mass balance that mixes them cannot be reconciled.
• Watch the substitutions. If a conventional lining replaces a recycled one part way through a run, the percentage for that lot changes and the TC for it should change too.
• Treat each colourway on its own numbers. A colourway dyed on a different base cloth may not carry the same recycled content as the one you certified first.
• Recalculate when the specification changes. A heavier buckle or a thicker foam reduces the percentage even when nothing about the certified input changed.
• Keep the claim tied to the lot. Different lots can legitimately carry different percentages; a single product page number has to be the lowest one you can evidence.

The substitution point is the one that connects this page to the rest of the programme. A component swapped for a conventional equivalent under time pressure does not just change the product, it changes the claim, and it changes it on a lot that has already been shipped and described. That is the same failure as any other unrecorded substitution, and the control is the same written change note with the same contractual consequence.

How Long Is a TC Valid, and What Is the Transaction Window?

A TC is not a licence with an expiry you can diary. It is a record of one transaction, and its authority comes from being issued for that transaction inside the window the standard permits. The document does not expire so much as it stops being usable once it is disconnected from the shipment it describes, and the two things that disconnect it are time and a change in the goods.

The window matters commercially because it is short. A TC has to be applied for and issued around the date of the transaction, and an application made months after the goods moved is either refused or issued as an exception, both of which are visible on the document. Treat the request as part of the shipping document set and not as an afterthought, and confirm the current window with the certification body rather than with a supplier summary.

The second limit is scope. A TC covers the quantity stated on it, and no more. If the same style is produced again next quarter, that run needs its own TC with its own number, even when the material is identical and the supplier is unchanged. Buyers routinely assume a TC covers a style rather than a shipment, and they discover otherwise when a marketplace asks for documentation on the specific units they are selling.

What Other Evidence Should Sit Next to the TC?

A TC proves the recycled content of a transaction. It does not prove the bag is safe, legal, or correctly made, and those are separate questions with separate documents. A complete lot file for a certified bag programme has five documents in it, and a buyer who assembles all five can answer almost any question from a regulator, a marketplace or a retail compliance team without going back to the supplier.

• The transaction certificate, naming your entity as buyer, matched to the invoice, the packing list and the bill of lading.
• The supplier scope certificate, current, with product categories that cover what you bought.
• The commercial invoice and packing list for the shipment, which is what the TC is reconciled against.
• A restricted substance test report covering REACH Annex XVII, CA Prop 65 and CPSIA as applicable to your market, because recycled input does not exempt a product from chemical compliance.
• The AQL 2.5 inspection report under ISO 2859-1 for the same lot, because a certified material can still be badly assembled.

The fourth item is the one that surprises people. Recycled content and chemical compliance are independent. A post-consumer recycled polyester shell still has to meet the restricted substance limits for the market it is sold in, and recycled streams carry a higher variability risk than virgin ones because the input history is less controlled. Test the finished article, not the claim.

How Do You Write GRS Requirements Into a Purchase Order?

In six lines, and they belong in the body of the order next to the specification rather than in an appendix. Each line closes a gap that a supplier can otherwise drive a container through without ever having lied to you.

1. Name the standard and the claim. The recycled content standard you are claiming under, and the percentage and pre-consumer or post-consumer split you intend to state.
2. Require both parties to be certified. The supplier must hold a current scope certificate covering the product category, and must maintain it through the life of the order.
3. Make the TC a shipping document. A TC naming your legal entity as buyer must be delivered with the invoice and the packing list, before or with the shipment.
4. Fix the product description and the quantity. The description must match the commercial invoice line, and the covered weight must equal the shipped quantity.
5. Require the input references. The upstream TC numbers for the certified input must appear on the document so the chain is visible one step up.
6. Attach a consequence. An order shipped without a valid TC, or with a TC that fails reconciliation, is a breach with a stated remedy and a stated effect on payment.
