What it means	Vottunarstofan Tún is Iceland's only accredited organic certifier. Accredited by MAST (Matvælastofnun) under the EU 2018/848-equivalent Icelandic standard, so a Tún-certified product is also recognised as EU-organic.	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.	The European Commission's voluntary environmental label. Covers cleaning products, paper, textiles, electronics, accommodation services. NOT an organic mark.	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.

Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.	Lifecycle-based environmental criteria per product category. Restrictions on hazardous chemicals. Annual licence renewal with audit.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare and biodynamic-compatible production options.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	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.	Doesn't apply to food. Doesn't mean organic.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.
