For Southeast Asian exporters of women's blouses and shirts, navigating textile compliance requirements can feel overwhelming. Two certifications dominate global conversations: OEKO-TEX Standard 100 and EU REACH. While often mentioned together, they serve different purposes and carry different legal weight.
OEKO-TEX Standard 100 is a voluntary commercial certification that tests for harmful substances in textiles. It's not a legal requirement, but rather a market expectation—especially for EU and North American buyers. The certification covers over 350 regulated substances including formaldehyde, heavy metals, phthalates, and azo dyes. Starting June 1, 2026, OEKO-TEX introduces updated limit values and new PFAS (per- and polyfluoroalkyl substances) restrictions, with a 3-month transition period for suppliers to adapt [1].
EU REACH, on the other hand, is a legal regulation that applies to all products sold in the European Union. REACH requires registration, evaluation, authorization, and restriction of chemicals. The SVHC (Substances of Very High Concern) threshold is 0.1% by weight—any product exceeding this limit requires notification to ECHA. Annex XVII Entry 72 specifically restricts azo dyes that release certain aromatic amines, which is highly relevant for dyed blouses and shirts [2].
"OEKO-TEX is like the baseline—it's about safety, not about sustainability. If you want organic, you need GOTS. But for basic safety compliance, OEKO-TEX is what buyers expect." [3]
