What it meansVottunarstofan 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.National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.Launched April 2023 by the OEKO-TEX Association. A separate certificate from Standard 100 that combines the Standard 100 chemical-residue test with verified organic-cotton supply chain — addressing the long-standing confusion that Standard 100 alone is 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).
  • Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce.
  • Annual on-site inspection.
  • Biodynamic certification option.
  • Two grades: 'Organic Cotton' (100% certified-organic cotton) and 'Organic Cotton Blended' (≥70% certified-organic cotton).
  • Full Standard 100 chemical residue test on the finished product.
  • Additional GMO test + pesticide residue test specific to organic farming.
  • Verified chain of custody from farm to finished product.
  • Annual re-certification with independent OEKO-TEX institute audits.
Does NOT
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
  • Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).
  • Doesn't certify the social/labour conditions across the supply chain in the way GOTS does (use OEKO-TEX STeP for that, or pair with GOTS).
  • Cotton-only — doesn't apply to other organic fibres (wool, hemp, linen).
