What it means	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.	Finland's national organic 'Sun Mark' (Aurinkomerkki). Operated by the Finnish Food Authority. In practice most Finnish organic packaging carries both Luomu and the EU Leaf — they certify to the same baseline.	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.	Sustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.

Guarantees	≥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).	EU baseline organic (Finnish supply chains end-to-end). Annual on-site inspection by the Finnish Food Authority.	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.	Reduced (not eliminated) synthetic pesticide use, with bans on the most hazardous classes. Forest conservation requirements (no deforestation after the cut-off date). Worker welfare and community development requirements. Annual third-party audit.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	The Sun Mark is awarded only to fully Finnish supply chains — imports use the EU Leaf alone.	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.	Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.
