What it means	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.	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).	The US Department of Agriculture's national organic standard. The green-and-white seal is the legal mark for any food sold as 'organic' in the United States.

Guarantees	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.	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.	At least 95% of ingredients are certified organic (the '100% Organic' variant requires every ingredient). No synthetic pesticides, no synthetic fertilizers, no GMOs, no sewage sludge, no irradiation. Annual on-site inspection by a USDA-accredited certifier. Residue testing on at least 5% of certified operations each year.
Does NOT	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.	Same standard as the EU Leaf — not stricter.	Doesn't certify clinical effectiveness or skin tolerance.	Doesn't certify nutrition, taste, or animal welfare specifically (separate marks like AWA cover welfare). Doesn't guarantee local production — a 'USDA Organic' product can be grown anywhere with an accredited inspector.
