What it means	Tests 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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	The leading certification for organic cosmetics in Europe. Two grades: COSMOS Organic (≥95% organic agricultural ingredients) and COSMOS Natural (no organic minimum, but the same restricted-ingredient list).	The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.

Residue testing	Required (this is the entire point)	GMO testing only (not pesticide)	Risk-based	Required for finished products
Guarantees	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	COSMOS Organic: ≥95% organic agricultural ingredients. COSMOS Natural: minimum natural-origin ingredients with banned synthetic restrictions. No GMOs, no parabens, no PEGs, no synthetic fragrances, no SLS/SLES. Biodegradability requirements. Annual on-site audit.	≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%). Restricted dyes, no chlorine bleach, no formaldehyde, no banned heavy metals. Wastewater treatment requirements. Social standards based on ILO core conventions (no child labour, no forced labour, fair wages, safe workplace). Annual on-site inspection by IOAS-accredited certifier.
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 — Non-GMO products can use synthetic pesticides and fertilizers freely.	Doesn't certify clinical effectiveness or skin tolerance.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
