What it means	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.	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.	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.	Vottunarstofan Tún is Iceland's only accredited organic certifier. Accredited by MAST (Matvælastofnun) under the EU 2018/848-equivalent Icelandic standard, so a Tún-certified product is also recognised as EU-organic.

Guarantees	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.	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.	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	≥95% organic ingredients per EU rules. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).
Does NOT	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.	Outside Denmark, retailers usually rely on the EU Leaf rather than the Ø.	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.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
