Guarantees
  • Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce.
  • Annual on-site inspection.
  • Biodynamic certification option.
  • 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
  • Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).
  • 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.
