How to Verify rPET Bag Recycled-Content Claims
rPET bag claims: the documents to request before ordering
For a UAE campaign, retail programme or staff issue, the useful procurement question is not simply whether a supplier can say “recycled”. It is what that statement covers, how it is evidenced for the chosen configuration and whether the wording can be repeated accurately in a tender, artwork approval or product description. rPET means recycled PET: PET material recovered for reprocessing. It does not, on its own, establish the origin of every part of a finished bag or the impact of the order.
Start with the product definition rather than the headline. A bag may have a main fabric, lining, handles, webbing, zip, binding, label, coating, print, reinforcement board and packing. A recycled-content statement may relate only to the main fabric. That can be supportable if it is stated at component level, but it should not become a claim that the complete bag is recycled unless the evidence and calculation cover the finished item.
For a configuration selected from rPET bags, ask for the exact item description or specification to appear in supporting paperwork: fabric construction, colour, bag model and relevant trim or finish. A generic document for “recycled fabric” may not demonstrate the composition of the precise bag. Match documents to the approved sample and production specification, not just the category name.
Make the recycled-content claim specific
Before accepting a percentage claim, establish its basis. Is it calculated by weight of the fabric component, all textile components or the complete bag? Does it refer to material before cutting and making, or the finished item? Keep this basis with the percentage in the buyer’s record. It prevents a product-page description, campaign brief or on-pack message from silently expanding a limited component claim.
Ask whether the stated recycled content is pre-consumer, post-consumer or a mixture. Use those terms only when the supplier’s documents say so. It is not safe to infer post-consumer input merely because a bag is described as rPET, or to assume every rPET bag is made from bottles. Where the source is undocumented, keep the wording to documented recycled PET content, or omit source detail.
Do not let a component claim travel to unrelated products. If an rPET bag is one element of a set from promotional gifts, its evidence does not extend to the contents, packaging or other components. Likewise, “non-woven” on a product in non-woven bags describes construction; it is not proof of a particular fibre, recycled-content percentage or source. Treat each component as its own evidence question.
Understand scope and transaction documents
Chain-of-custody documents can help assess whether a claim has been controlled through the supply chain, but their limits matter. Textile Exchange says a scope certificate shows that a company has been qualified to produce certified products, while a transaction certificate applies to specific products under the relevant standard. Its chain-of-custody guidance is a useful starting point for separating company status from evidence for a particular supply transaction.
A scope certificate is not proof that every bag offered by that company is certified, or that the bag in front of you is covered. A transaction certificate can be tied more closely to a defined product or shipment where the relevant scheme and order are subject to that process. It is not a universal document for every purchase and is not automatically a legal requirement. The appropriate request depends on the proposed claim, supply route and available evidence.
Request the company name and address, certificate issuer, reference, scope of activities, material or product coverage, issue and expiry dates, and covered sites. Compare these with the party carrying out the relevant role. A spinner, fabric mill, bag maker, trader and exporter may be different companies. A valid document for one party is not automatically evidence for another party’s product or sales order.
Verify validity, relevance and the chain of custody
For transaction-level paperwork, compare the product description, material designation, quantities or weights, dates, buyer and seller, and available order or invoice references. The description should align with the approved bag specification, not a broad product family. If a document concerns fabric, record that limit rather than treating it as proof for zips, handles or the assembled bag. Where the claim concerns the finished item, ask how fabric evidence is maintained through making-up.
Do not rely on a logo, cropped certificate image or old PDF alone. Textile Exchange advises verification by contacting the issuing certification body and notes that its certified-company database can lag by weeks. Retain the issuer’s response or a dated verification note. The organisation’s certificate-verification FAQ sets out these checks. Validity is only one test: a current certificate may cover different materials, processes, sites or product categories from the order.
Set the request before production approval. A practical evidence pack can include the dated product specification, component-level composition information, supplier declaration, relevant certificate copies, issuer-verification record where used, quotation or purchase-order references, final approved claim and correspondence explaining exclusions. The objective is traceability between the words used and the item ordered, not a large collection of generic marketing material.
Use narrow wording where evidence is incomplete
Missing paperwork should not be hidden or filled with assumptions. If an order proceeds before all evidence is available, restrict the wording to what is supported or pause the related claim. If the supporting evidence is still pending, mark the claim as unverified in the internal record and do not publish it until the documentation has been reviewed. Do not upgrade that into “fully recycled”, “made from bottles” or “certified bag” without matching evidence.
Recycled content does not prove that a finished bag is recyclable everywhere, biodegradable, plastic-free or suitable for a particular waste system. It does not by itself demonstrate impact savings. Those are separate claims with their own evidence requirements and may depend on design, additives, local collection and end-of-life infrastructure. Keeping the claim to documented recycled PET content is clearer for procurement teams and downstream users.
Build a repeat-order file rather than assuming an earlier approval carries forward. Retain reviewed documents, approved wording, sample reference, purchase-order number and the reasoning behind component limits. On a re-order, compare fabric source, mill, factory, bag specification, colour, print method, trim, quantities, order dates and invoicing party. A change can mean the earlier evidence no longer supports the new order and should be reconfirmed.
Ask early, then record the answer
Clarify the claim before artwork approval, not after delivery. Give the supplier the proposed wording and ask which documents can support that wording for the specified bag.

Frequently asked questions
Does a scope certificate prove that every rPET bag is certified?
No. A scope certificate can show that a company has been assessed and qualified within the stated scope, but it does not automatically cover every product it sells. Check the certificate’s activities, sites and validity, then seek evidence that relates to the exact bag, material and order being considered.
Can we say an rPET bag is made from post-consumer material?
Only when documentation for the selected material supports that source description. rPET means recycled PET, but it does not automatically identify the feedstock as post-consumer or confirm that bottles were used. If source information is missing, keep the wording to documented recycled PET content and do not infer more.
Is a transaction certificate required for every order?
No. Whether transaction-level documentation is relevant depends on the applicable scheme, the supply route and the claim proposed for that order. It is not a universal requirement for every bag purchase and not automatically a legal requirement. Ask which documents apply before approving production or publishing a claim.
Can a recycled-content percentage describe the whole bag?
Only if the calculation and evidence cover the complete finished bag. A percentage may instead refer to fabric by weight or another defined component. Record the calculation basis with the claim, identify excluded items such as handles or hardware, and avoid presenting a component figure as a whole-bag figure.
When should evidence be reviewed for a repeat rPET bag order?
Review the evidence pack again when the fabric source, factory, bag construction, trims, print, order dates, quantities or invoicing party changes. Retain the earlier approval, but do not treat it as automatic proof for a new order. Reconfirm that the proposed wording remains supported by current, relevant documentation.
