OEKO-TEX Standard: definition

OEKO-TEX is a family of independent testing and certification standards developed by the OEKO-TEX Association, designed to verify that textile products are free from harmful levels of chemical substances. The most widely recognised standard, OEKO-TEX Standard 100, tests every component of a finished textile product, including threads, buttons, and zips, against a list of over 100 harmful substances. OEKO-TEX MADE IN GREEN extends this to cover social and environmental production criteria. OEKO-TEX STeP (Sustainable Textile Production) certifies production facilities. For consumers, OEKO-TEX labels provide assurance that products are safe to wear. For fashion professionals, understanding OEKO-TEX standards is essential in chemical compliance, quality assurance, and sustainable sourcing roles.
