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.A 'beyond organic' standard developed by the Regenerative Organic Alliance (Patagonia, Rodale Institute, Dr. Bronner's, others). Built on top of USDA Organic; adds soil health, animal welfare, and social fairness pillars.

Guarantees
  • All organic standards PLUS biodynamic preparations and whole-farm planning.
  • Whole-farm certification (not single fields/products).
  • Annual on-site inspection by Demeter-accredited inspectors.
  • Animal welfare standards stricter than baseline organic.
  • ≥95% organic ingredients per EU rules.
  • No synthetic pesticides, no GMOs.
  • Annual on-site inspection.
  • Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).
  • USDA Organic baseline (or equivalent) is a prerequisite.
  • Soil health: cover cropping, no-till or reduced-till, conservation crop rotation, compost.
  • Animal welfare: pasture-based, Five Freedoms, prohibits factory-farm conditions.
  • Social fairness: living wage, freedom of association, safe workplace, no forced or child labour.
  • Three tiers: Bronze, Silver, Gold based on adoption depth.
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.
  • Newer label (2018+) — supply still limited, mostly US brands.
