What it means	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.	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.	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.

Animal welfare standards (outdoor access, lower stocking density).
Does NOT	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	Doesn't certify clinical effectiveness or skin tolerance.	Same standard as the EU Leaf — not stricter.	Logo is trademarked — not a free-licence mark.
