What it means	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.	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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	France-based independent certifier operating in 130+ countries. One of the world's largest organic + cosmetics + textile certifiers. The 'Ecocert' wordmark on a package usually means Ecocert was the accredited body that ran the inspection against the national/EU standard.

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.	≥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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	Inspection against the relevant national or private organic standard (EU 2018/848, USDA NOP, COSMOS, GOTS, Fair for Life, etc.). Annual on-site inspection. Accredited under multiple national systems including USDA NOP and EU 2018/848.
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).	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Ecocert is the certifier, not the standard — the actual rules come from whichever organic regulation the product is certified under.
