	Bio-Siegel (Germany) Germany · Tier 1 Gold	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	Bioland Germany · Tier 2 Trusted	Non-GMO Project Verified United States · Tier 3 Specialty
What it means	Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.	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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.
Scope	Food	Textiles	Food	Food
Established	2001	1992	1971	2010
Inspection	Annual on-site by EU-accredited German control body	Annual on-site + lab testing of finished products	Annual on-site by Bioland-accredited inspectors	Annual third-party audit + lab testing
Residue testing	Risk-based	Required (this is the entire point)	Required	GMO testing only (not pesticide)
Guarantees	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	Same standard as the EU Leaf — not stricter.	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.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
