What it means	The 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.	The official environmental label of the Nordic countries (Sweden, Norway, Denmark, Finland, Iceland). Covers ~60 product categories from cleaning products to hotels — NOT specifically an organic standard.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.

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).	Lifecycle-based environmental criteria for the product category. Restrictions on hazardous chemicals. Recyclability and packaging requirements. Audited every 3-5 years against an updated standard.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.
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.	Doesn't certify food as organic — Nordic Swan on a food package means lower-environmental-impact, not 'no synthetic pesticides'.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.
