	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	Non-GMO Project Verified United States · Tier 3 Specialty	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	Bioland Germany · Tier 2 Trusted
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 word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.
Scope	Textiles	Food	Several categories	Food
Established	1992	2010	—	1971
Inspection	Annual on-site + lab testing of finished products	Annual third-party audit + lab testing	None	Annual on-site by Bioland-accredited inspectors
Residue testing	Required (this is the entire point)	GMO testing only (not pesticide)	None	Required
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.	Nothing. It is not a certification and there is no body verifying anything.	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	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 mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	Like Naturland, membership-based — only Bioland-association farms can use the mark.
