	Global Organic Textile Standard Global · Tier 2 Trusted	SisOrg — Produto Orgânico Brasil Brazil · Tier 1 Gold	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	Tún (Iceland) Iceland · Tier 1 Gold
What it means	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.	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 word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	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.
Scope	Textiles	Food	Several categories	Food
Established	2002	2009	—	1994
Inspection	Annual on-site, IOAS-accredited	Annual on-site, MAPA-accredited	None	Annual on-site, MAST-accredited
Residue testing	Required for finished products	Required for export	None	Required for at-risk operations
Guarantees	≥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 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.	Nothing. It is not a certification and there is no body verifying anything.	≥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	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	OPAC (peer-review) certified products are valid in Brazil but typically not accepted for export — exporters need third-party (e.g. IBD).	Doesn't mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
