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.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	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.	Launched April 2023 by the OEKO-TEX Association. A separate certificate from Standard 100 that combines the Standard 100 chemical-residue test with verified organic-cotton supply chain — addressing the long-standing confusion that Standard 100 alone is NOT an organic mark.
Scope	Textiles	Food	Food	Textiles
Established	1992	1971	2001	2023
Inspection	Annual on-site + lab testing of finished products	Annual on-site by Bioland-accredited inspectors	Annual on-site by MAFF-registered certifier	Annual on-site by OEKO-TEX-accredited institute (Hohenstein et al.)
Residue testing	Required (this is the entire point)	Required	Required for high-risk operations	Required (Standard 100 panel + GMO/pesticide screening)
Guarantees	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.	≥95% organic ingredients. No synthetic pesticides, no synthetic fertilizers, no GMOs. Annual inspection by a MAFF-registered certifier.	Two grades: 'Organic Cotton' (100% certified-organic cotton) and 'Organic Cotton Blended' (≥70% certified-organic cotton). Full Standard 100 chemical residue test on the finished product. Additional GMO test + pesticide residue test specific to organic farming. Verified chain of custody from farm to finished product. Annual re-certification with independent OEKO-TEX institute audits.
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.	Like Naturland, membership-based — only Bioland-association farms can use the mark.	Mutual recognition with the US, EU, and Canada applies to specific product categories — check each agreement before importing.	Doesn't certify the social/labour conditions across the supply chain in the way GOTS does (use OEKO-TEX STeP for that, or pair with GOTS). Cotton-only — doesn't apply to other organic fibres (wool, hemp, linen).
