What it meansThe certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.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.France-based independent certifier operating in 130+ countries. One of the world's largest organic + cosmetics + textile certifiers. The 'Ecocert' wordmark on a package usually means Ecocert was the accredited body that ran the inspection against the national/EU standard.

Does NOT
  • Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
  • Ecocert is the certifier, not the standard — the actual rules come from whichever organic regulation the product is certified under.
