What it means	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.	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).	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.	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.

Does NOT	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Doesn't certify clinical effectiveness or skin tolerance.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	Same standard as the EU Leaf — not stricter.
