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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT 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.	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.

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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	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 per EU rules. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).
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.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Doesn't certify food as organic — Nordic Swan on a food package means lower-environmental-impact, not 'no synthetic pesticides'.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
