	Global Organic Textile Standard Global · Tier 2 Trusted	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	Non-GMO Project Verified United States · Tier 3 Specialty	Bioland Germany · Tier 2 Trusted
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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.
Scope	Textiles	Textiles	Food	Food
Established	2002	1992	2010	1971
Inspection	Annual on-site, IOAS-accredited	Annual on-site + lab testing of finished products	Annual third-party audit + lab testing	Annual on-site by Bioland-accredited inspectors
Residue testing	Required for finished products	Required (this is the entire point)	GMO testing only (not pesticide)	Required
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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	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.
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.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Like Naturland, membership-based — only Bioland-association farms can use the mark.
