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.	Norway's only accredited organic certifier. The Ø-merket is required on any food sold as 'økologisk' in Norway. Operates to EU 2018/848 equivalence plus Norwegian add-ons.	Denmark's national organic mark, owned by the Danish Veterinary and Food Administration. The red Ø is one of the most-trusted food labels in the world — recognised by ~98% of Danish consumers.

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.	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).	EU baseline organic (EU 2018/848). Annual on-site inspection by the Danish Veterinary and Food Administration. Direct government control (not a private body) — the unusual Danish model that drives high consumer trust.
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.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.	Outside Denmark, retailers usually rely on the EU Leaf rather than the Ø.
