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.	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.
Scope	Several categories	Food	Food
Established	1986	2001	1971
Inspection	Annual on-site, NASAA-accredited	Annual on-site by EU-accredited German control body	Annual on-site by Bioland-accredited inspectors
Residue testing	Risk-based	Risk-based	Required
Guarantees	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.
Does NOT	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	Same standard as the EU Leaf — not stricter.	Like Naturland, membership-based — only Bioland-association farms can use the mark.
