Verify the named company, site, standard, scope, validity and product relationship. A supplier's general certificate does not by itself prove recycled content in your exact fabric or shipment.
Check the certificate holder
Confirm that the company named on the document is part of your actual supply route. Similar trading names or a related mill are not automatically equivalent.
Match the scope to the product
Read which materials, processes and facilities are covered. Ask how the chosen fabric article connects to that scope.
Distinguish scope and transaction evidence
A scope certificate shows that an entity is certified for defined activities; shipment or transaction documentation supports the claim for a specific flow of goods.
Keep marketing language precise
Use only the claim supported by the evidence you retain. Avoid turning a fiber or supply-chain statement into a broader environmental promise.
