What it meansSustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.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 national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.

Does NOT
  • Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
  • Same standard as the EU Leaf — not stricter.
