What it means	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.	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.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	Brazil's national organic mark under the Sistema Brasileiro de Avaliação da Conformidade Orgânica, administered by MAPA. Required on any food sold as 'orgânico' in Brazil.

Residue testing	Required for at-risk operations	Required on ≥5% of operations annually	Required	Required for export
Guarantees	≥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).	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.	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.	≥95% organic ingredients per Brazilian Organic Law 10.831/2003. Annual on-site inspection by MAPA-accredited certifier OR a participatory-guarantee group (OPAC). Two valid pathways: third-party certification OR a peer-reviewed OPAC system.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	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.	Like Naturland, membership-based — only Bioland-association farms can use the mark.	OPAC (peer-review) certified products are valid in Brazil but typically not accepted for export — exporters need third-party (e.g. IBD).
