What it meansNorth America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.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.Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.

  • Annual third-party verification.
  • Tracing and segregation across the supply chain.
  • ≥95% organic ingredients per EU rules.
  • No synthetic pesticides, no GMOs.
  • Annual on-site inspection.

  • Whole-farm conversion (no parallel conventional production).
  • Lower permitted nitrogen inputs than EU baseline.

Does NOT
  • Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
  • Like Naturland, membership-based — only Bioland-association farms can use the mark.
