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.	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.	The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	The mandatory mark for any pre-packaged organic food sold in the EU. The 'Euro-Leaf' is a stylised leaf made of twelve white stars on a green background.

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).	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.	≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%). Restricted dyes, no chlorine bleach, no formaldehyde, no banned heavy metals. Wastewater treatment requirements. Social standards based on ILO core conventions (no child labour, no forced labour, fair wages, safe workplace). Annual on-site inspection by IOAS-accredited certifier.	At least 95% of agricultural ingredients are organic (regulation EU 2018/848). No synthetic pesticides, no synthetic fertilizers, no GMOs. Animal welfare standards (outdoor access, lower stocking density, no routine antibiotics). Annual inspection by an accredited control body in the producing member state. Mandatory display of the certifier's code and origin (e.g. 'EU Agriculture' / 'Non-EU Agriculture').
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	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 cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Doesn't ban the natural pesticides allowed under the regulation (copper sulphate, spinosad). Doesn't certify processed-food additives beyond the EU's permitted list.
