What it means	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.	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.	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.

Animal welfare and biodynamic-compatible production options.	≥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.	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.
Does NOT	Like Naturland, membership-based — only Bioland-association farms can use the mark.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).
