'Natural' (NOT a certification)
Worldwide · Tier 4 Marketing
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.The word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.

  • 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. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced.
  • Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.
