  • 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.

  • Verified absence of GMO ingredients (with action thresholds, not zero tolerance).
  • Annual third-party verification.
  • Tracing and segregation across the supply chain.
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.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
  • Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
