	Tún (Iceland) Iceland · Tier 1 Gold	IFM IFOAM — Organics International Global · Tier 2 Trusted	Non-GMO Project Verified United States · Tier 3 Specialty	Australian Certified Organic Australia · Tier 1 Gold
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 international umbrella body for the organic movement. Not a product label — IFOAM accredits other certifiers worldwide via the IFOAM Family of Standards. If a cert is 'IFOAM-accredited' it has been benchmarked to a globally consistent baseline.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	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.

Guarantees	≥95% organic ingredients per EU rules. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).	Accredited certifiers meet the IFOAM Norms and the IFOAM Family of Standards. Independent peer review of certifier governance, inspection rigor, and conflict-of-interest controls.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	≥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.	Does NOT certify products directly — only certifiers. Look for the underlying national / private mark on the package.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.
