	Bio-Siegel (Germany) Germany · Tier 1 Gold	Non-GMO Project Verified United States · Tier 3 Specialty	Soil Association Organic United Kingdom · Tier 2 Trusted	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · 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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	The UK's largest organic certifier. Standards are stricter than the UK government's baseline (which still mirrors EU 2018/848 post-Brexit). Recognised by the EU and USA under equivalence.	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.

Guarantees	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming. Annual on-site inspection. Animal welfare standards (outdoor access, lower stocking density).	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.
Does NOT	Same standard as the EU Leaf — not stricter.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Logo is trademarked — not a free-licence mark.	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.
