What it means	Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.	New Zealand's largest organic certifier. Recognised by the EU, US, and Japan under their respective import-equivalence regimes.	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	Textiles	Several categories	Several categories	Textiles

Inspection	Annual on-site + lab testing of finished products	Annual on-site, IFOAM-accredited	None	Annual on-site, IOAS-accredited
Residue testing	Required (this is the entire point)	Risk-based	None	Required for finished products
Guarantees	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Covers food, textiles, and personal care under separate standards.	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	Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.	New Zealand has no single legally-mandated 'organic' definition — voluntary certification is the norm.	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.
