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.	Reduced (not eliminated) synthetic pesticide use, with bans on the most hazardous classes. Forest conservation requirements (no deforestation after the cut-off date). Worker welfare and community development requirements. Annual third-party audit.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
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.	Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
