What it meansTests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.The word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.

Guarantees
  • Finished textile tested against the OEKO-TEX harmful-substance limit list.
  • Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.
  • Nothing. It is not a certification and there is no body verifying anything.
  • Verified absence of GMO ingredients (with action thresholds, not zero tolerance).
  • Annual third-party verification.
  • Tracing and segregation across the supply chain.
Does NOT
  • Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.
  • Doesn't mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced.
  • Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.
  • Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
