	Tún (Iceland) Iceland · Tier 1 Gold	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	SisOrg — Produto Orgânico Brasil Brazil · Tier 1 Gold	Global Organic Textile Standard Global · Tier 2 Trusted
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.	Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.	Brazil's national organic mark under the Sistema Brasileiro de Avaliação da Conformidade Orgânica, administered by MAPA. Required on any food sold as 'orgânico' in Brazil.	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.

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).	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	≥95% organic ingredients per Brazilian Organic Law 10.831/2003. Annual on-site inspection by MAPA-accredited certifier OR a participatory-guarantee group (OPAC). Two valid pathways: third-party certification OR a peer-reviewed OPAC system.	≥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.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.	OPAC (peer-review) certified products are valid in Brazil but typically not accepted for export — exporters need third-party (e.g. IBD).	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
