What it means	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	The UK's largest organic certifier. Standards are stricter than the UK government's baseline (which still mirrors EU 2018/848 post-Brexit). Recognised by the EU and USA under equivalence.	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.	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.
Scope	Food	Several categories	Several categories	Textiles
Established	2010	1946	—	2002

Residue testing	GMO testing only (not pesticide)	Risk-based	None	Required for finished products
Guarantees	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming. Annual on-site inspection. Animal welfare standards (outdoor access, lower stocking density).	Nothing. It is not a certification and there is no body verifying anything.	≥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	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Logo is trademarked — not a free-licence mark.	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.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
