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.Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.

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.
