	IFM IFOAM — Organics International Global · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold	Bio-Siegel (Germany) Germany · Tier 1 Gold	Global Organic Textile Standard Global · Tier 2 Trusted
What it means	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.	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.	Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.	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.
Scope	Several categories	Food	Food	Textiles
Established	1972	1994	2001	2002

Residue testing	Delegated to accredited certifiers	Required for at-risk operations	Risk-based	Required for finished products
Guarantees	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.	≥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).	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	≥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.
Does NOT	Does NOT certify products directly — only certifiers. Look for the underlying national / private mark on the package.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Same standard as the EU Leaf — not stricter.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
