What it means	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.	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.	Sustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.	Japan's national organic standard under the Japanese Agricultural Standard system. The mark must appear on any food sold as 'organic' (有機 or オーガニック) in Japan.

Guarantees	≥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.	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	Reduced (not eliminated) synthetic pesticide use, with bans on the most hazardous classes. Forest conservation requirements (no deforestation after the cut-off date). Worker welfare and community development requirements. Annual third-party audit.	≥95% organic ingredients. No synthetic pesticides, no synthetic fertilizers, no GMOs. Annual inspection by a MAFF-registered certifier.
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	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.	Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.	Mutual recognition with the US, EU, and Canada applies to specific product categories — check each agreement before importing.
