GOTS vs OEKO-TEX vs GRS: Which Certification Matters for Branded Apparel?

Three logos, three completely different promises. Here's what each certification actually covers — and which one to require depending on what you're ordering.

Comparison of GOTS, OEKO-TEX Standard 100 and GRS textile certifications

Every product we sell carries at least one independent textile certification — and if you've browsed our store, you've seen the badges: GOTS, OEKO-TEX, GRS. It's the question we get most often from buyers: which one actually matters?

The short answer: they're not competing standards. They certify completely different things, and the best products combine two or more of them.

  • GOTS certifies organic fibre content — plus environmental and social criteria across the entire supply chain.
  • OEKO-TEX Standard 100 certifies chemical safety — the finished product is tested for harmful substances.
  • GRS certifies recycled content — verified through the chain of custody, with social and chemical requirements on top.

GOTS — organic, from field to fashion

The Global Organic Textile Standard is the strictest of the three in scope. It requires certified organic fibres (no synthetic pesticides, no GMOs) and audits every processing step — dyeing, printing, sewing — against environmental and social criteria. Independent bodies inspect the whole chain annually.

GOTS is the certification to require for natural fibres: organic cotton tees, sweatshirts, and tote bags. What it can't tell you: whether a product contains recycled materials — that's GRS territory.

OEKO-TEX Standard 100 — safe against the skin

OEKO-TEX Standard 100 answers a different question entirely: is the finished garment safe to wear? Every component — fabric, sewing thread, buttons, prints — is lab-tested against limit values for around 1,000 harmful substances, often stricter than legal requirements.

It says nothing about where the fibres came from or how workers were treated. But as a baseline for anything your team wears against their skin, it's the one certification we'd call non-negotiable. That's why you'll find it on many garments in our range, always alongside GOTS or GRS.

Deep dive: what OEKO-TEX Standard 100 means.

GRS — recycled content you can verify

The Global Recycled Standard exists because "made from recycled materials" is one of the easiest claims to greenwash. GRS verifies the recycled percentage through every step of the chain of custody, and adds social criteria and chemical restrictions on top.

GRS is what to require for synthetic fibres — recycled polyester and nylon in t-shirts, caps, and bags. A product needs at least 20% recycled content to be certified, and 50% to carry the GRS logo.

What about OCS 100 and PETA-Approved Vegan?

Two more labels you'll see in our range. OCS 100 verifies organic fibre content like GOTS, but without GOTS's processing and social requirements — think of it as "GOTS light", common on totes and accessories. PETA-Approved Vegan confirms no animal-derived materials anywhere in the product — relevant if your company has a vegan or animal-welfare policy.

So which should you require?

It depends on what you're ordering and why:

  • Team swag people will wear (tees, hoodies): OEKO-TEX as the baseline, plus GOTS for cotton or GRS for recycled polyester.
  • Sustainability reporting: GOTS and GRS both provide chain-of-custody verification you can actually cite — vague "eco-friendly" claims don't survive an audit.
  • Vegan or animal-welfare policy: add PETA-Approved Vegan to the list.

Every textile product in our store, with its certifications

Every textile product we sell is third-party certified. Here is the current range, taken directly from the certification section of each product page — the strongest pieces combine three or more standards:

Non-textile items — like the stainless steel water bottle, mug, notebook, and mouse pad — fall outside textile certification schemes, which is why you won't see these labels on them. The full overview of what each standard covers is on our certifications page.
