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.
  • Imported organic foods must be re-certified under the Chinese standard — overseas certifications alone are not accepted for the 有机 label.
