What it means	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	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.
Scope	Food	Textiles	Food	Textiles
Established	1971	2023	2010	2002
Inspection	Annual on-site by Bioland-accredited inspectors	Annual on-site by OEKO-TEX-accredited institute (Hohenstein et al.)	Annual third-party audit + lab testing	Annual on-site, IOAS-accredited
Residue testing	Required	Required (Standard 100 panel + GMO/pesticide screening)	GMO testing only (not pesticide)	Required for finished products
Guarantees	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.	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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	≥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.
Does NOT	Like Naturland, membership-based — only Bioland-association farms can use the mark.	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).	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
