What it meansThe 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.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.

  • ≥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.
  • 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.

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 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).
