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.	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.	A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.

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.	Nothing. It is not a certification and there is no body verifying anything.	Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards). Annual on-site inspection. Fair-pricing requirements for member farmers.
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.	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.	Membership-based — only farms that join the Naturland association can use the mark.
