## 1. Executive Summary & Core Engineering Scope
GRS applies from 20% recycled content (logo at 50%+) and adds social, environmental and chemical criteria; RCS verifies the percentage from 5% with chain of custody only. Both are held by the resin supplier with a transaction certificate per lot.

Two Textile Exchange standards, one question from every retailer: can you prove the percentage on the pack? This guide separates what each certificate verifies, who in the supply chain actually holds it, what a transaction certificate is, and the two things no certificate does.

GRS (Global Recycled Standard) applies to products with 20% or more recycled content , requires 50% or more to carry the GRS logo , and adds social, environmental and chemical criteria at each certified site. RCS (Recycled Claim Standard) verifies the presence and amount of recycled material from 5% upward , chain of custody only. Both are held by the resin supplier and each converter , with a transaction certificate per lot . EU and UK retailers tend to ask for GRS by name. Neither certificate makes a pack recyclable or fixes its colour.

Both GRS and RCS are chain-of-custody standards administered by Textile Exchange. Both track recycled input through every processor, and both issue a transaction certificate per lot. The difference is scope: RCS stops at "this much of this lot is recycled"; GRS goes on to audit how each certified site is run.

A practical reading: if your pack will say "50% PCR" and you sell through EU or UK retail, plan for GRS, because that is what the buyer's compliance team will ask for and 50% is exactly the logo threshold. If your claim is 30% and your route is direct-to-consumer, RCS proves the number at lower cost to the chain. Neither is "better" in the abstract; they answer different questions.

This is where most PCR claims fall apart. The recycled content enters the chain at the resin supplier — the recycler that produces the PCR pellets. The moulding factory is a converter : it can be certified to handle GRS or RCS material, but it does not create the recycled content and it cannot certify a percentage on its own letterhead. For your claim to hold, three documents have to line up:
