What it meansLaunched 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.South America's largest organic certifier. IBD certifies under Brazilian, USDA NOP, EU, and JAS standards — a single-stop certifier widely used across Latin America.The Swiss organic farmers' federation mark. The Knospe (Bud) is the dominant organic mark in Swiss supermarkets and operates to standards stricter than the Swiss federal organic ordinance.

  • 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.
  • Multiple-standard certification: Brazilian (SisOrg), USDA NOP, EU, JAS, Demeter.

  • Whole-farm conversion.
  • Lower nitrogen inputs than the Swiss federal organic baseline.
  • Strong animal welfare requirements.

Does NOT
  • 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).
  • A single product may carry IBD plus a country-specific organic mark — IBD itself isn't the regulatory mark in any of those markets, just the accredited certifier.
  • Switzerland is outside the EU — the Knospe is recognised by the EU under the Switzerland-EU equivalence agreement, but not by USDA without further certification.
