What it means	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.	The Swiss organic farmers' federation mark. The Knospe (Bud) is the dominant organic mark in Swiss supermarkets and operates to standards stricter than the Swiss federal organic ordinance.	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	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.	Switzerland is outside the EU — the Knospe is recognised by the EU under the Switzerland-EU equivalence agreement, but not by USDA without further certification.	Same standard as the EU Leaf — not stricter.
