What it means	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.	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.	Norway's only accredited organic certifier. The Ø-merket is required on any food sold as 'økologisk' in Norway. Operates to EU 2018/848 equivalence plus Norwegian add-ons.

Guarantees	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.	≥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.	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).
Does NOT	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	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.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.
