What it meansThe 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 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.A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.

  • ≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%).

  • Annual on-site inspection by IOAS-accredited certifier.
  • 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.
  • Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards).

Does NOT
  • Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
  • 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.
  • Membership-based — only farms that join the Naturland association can use the mark.
