	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	Demeter International Global · Tier 2 Trusted	Bio-Siegel (Germany) Germany · Tier 1 Gold	Tún (Iceland) Iceland · Tier 1 Gold
What it means	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 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.	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.	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.
Scope	Textiles	Several categories	Food	Food
Established	1992	1928	2001	1994
Inspection	Annual on-site + lab testing of finished products	Annual on-site by Demeter-accredited inspectors	Annual on-site by EU-accredited German control body	Annual on-site, MAST-accredited
Residue testing	Required (this is the entire point)	Risk-based on top of organic	Risk-based	Required for at-risk operations
Guarantees	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	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.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	≥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).
Does NOT	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.	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.	Same standard as the EU Leaf — not stricter.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
