What it means	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).	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.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.

Does NOT	Doesn't certify clinical effectiveness or skin tolerance.	Same standard as the EU Leaf — not stricter.	Like Naturland, membership-based — only Bioland-association farms can use the mark.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.
