What it meansThe UK's largest organic certifier. Standards are stricter than the UK government's baseline (which still mirrors EU 2018/848 post-Brexit). Recognised by the EU and USA under equivalence.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.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
  • Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming.
  • Annual on-site inspection.
  • Animal welfare standards (outdoor access, lower stocking density).
  • 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.
  • ≥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
  • Logo is trademarked — not a free-licence mark.
  • 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.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
