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.	The leading certification for organic cosmetics in Europe. Two grades: COSMOS Organic (≥95% organic agricultural ingredients) and COSMOS Natural (no organic minimum, but the same restricted-ingredient list).	New Zealand's largest organic certifier. Recognised by the EU, US, and Japan under their respective import-equivalence regimes.	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.

Guarantees	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	COSMOS Organic: ≥95% organic agricultural ingredients. COSMOS Natural: minimum natural-origin ingredients with banned synthetic restrictions. No GMOs, no parabens, no PEGs, no synthetic fragrances, no SLS/SLES. Biodegradability requirements. Annual on-site audit.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Covers food, textiles, and personal care under separate standards.	Nothing. It is not a certification and there is no body verifying anything.
Does NOT	Same standard as the EU Leaf — not stricter.	Doesn't certify clinical effectiveness or skin tolerance.	New Zealand has no single legally-mandated 'organic' definition — voluntary certification is the norm.	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.
