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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	Mexico's national organic mark, administered by SENASICA under the Ley de Productos Orgánicos (LPO).
Scope	Several categories	Food	Food	Food
Established	1928	1994	2010	2006
Inspection	Annual on-site by Demeter-accredited inspectors	Annual on-site, MAST-accredited	Annual third-party audit + lab testing	Annual on-site, SENASICA-accredited
Residue testing	Risk-based on top of organic	Required for at-risk operations	GMO testing only (not pesticide)	Required
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).	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	≥95% organic ingredients per LPO. Annual on-site inspection by SENASICA-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 mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	USDA equivalence is granted product-by-product, not blanket.
