What it means	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.	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.	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.

Guarantees	≥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.	Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming. Annual on-site inspection. Animal welfare standards (outdoor access, lower stocking density).	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Logo is trademarked — not a free-licence mark.	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	Like Naturland, membership-based — only Bioland-association farms can use the mark.
