What it means	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.	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.	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.

Guarantees	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	≥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	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.	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.	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).
