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.	The US Department of Agriculture's national organic standard. The green-and-white seal is the legal mark for any food sold as 'organic' in the United States.	New Zealand's largest organic certifier. Recognised by the EU, US, and Japan under their respective import-equivalence regimes.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.
Scope	Textiles	Food	Several categories	Food
Established	1992	2002	1983	2010
Inspection	Annual on-site + lab testing of finished products	Annual on-site by USDA-accredited certifier	Annual on-site, IFOAM-accredited	Annual third-party audit + lab testing
Residue testing	Required (this is the entire point)	Required on ≥5% of operations annually	Risk-based	GMO testing only (not pesticide)
Guarantees	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	At least 95% of ingredients are certified organic (the '100% Organic' variant requires every ingredient). No synthetic pesticides, no synthetic fertilizers, no GMOs, no sewage sludge, no irradiation. Annual on-site inspection by a USDA-accredited certifier. Residue testing on at least 5% of certified operations each year.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Covers food, textiles, and personal care under separate standards.	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 certify nutrition, taste, or animal welfare specifically (separate marks like AWA cover welfare). Doesn't guarantee local production — a 'USDA Organic' product can be grown anywhere with an accredited inspector.	New Zealand has no single legally-mandated 'organic' definition — voluntary certification is the norm.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
