What it meansSustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.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.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
  • 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.
  • ≥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.
  • ≥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
  • Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.
  • Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
