GOTS vs GRS: When to Use Which

Both are credible certifications, and they are not interchangeable. Choosing the wrong one puts the claim — and the paperwork — at risk.

Lukas Brenner · Head of Compliance & MaterialsPublished

Green claims now carry legal weight, so the certificate has to match the fibre. The two we are asked about most — GOTS and GRS — cover different things and a mix-up is an audit finding, not a footnote.

GOTS is for organic

GOTS (Global Organic Textile Standard) governs organic natural fibres — cotton above all — across the whole chain from farm to finished garment, including the processing and the permitted chemical list.

  • Use it when the claim is "organic cotton" or "organic wool".
  • It covers both the fibre and how it is processed, dyed and finished.
  • The chain-of-custody file travels with the order.

GRS is for recycled

GRS (Global Recycled Standard) governs recycled content — recycled polyester from post-consumer bottles, recycled cotton from cutting waste, and so on.

  • Use it when the claim is "made from recycled" anything.
  • It sets the minimum recycled content and tracks it through the supply chain.
  • Blended products need the dominant claim to determine the standard.

A garment that is organic cotton with a recycled polyester trim may need both, and the labels must say so accurately. The certificate that does not match the claim is worse than no certificate, because it is a documented misstatement.

How we handle it

We source through audited mills and supply the chain-of-custody file with the bulk order, not after. The standard on the label matches the standard on the file, and the fibre in the garment matches both.
