Demystifying the world’s most recognized chemical safety label for trims and accessories. Understanding testing criteria across Product Classes I through IV.
The OEKO-TEX® Standard 100 is the world’s most trusted label for textiles and trims tested for harmful chemical substances. It certifies that every single component—from zipper pullers and sewing thread to shank buttons and elastic tape—has been rigorously screened against more than 350 regulated chemical substances.
Key testing criteria include a complete ban on carcinogenic azo dyes, strict nickel release limits below 0.28 µg/cm²/week under European Standard EN 1811, and total lead content under 90 ppm to satisfy US CPSIA requirements.
For brands exporting to Europe and North America, batch Certificates of Analysis (CoA) linked to valid OEKO-TEX certificate numbers are mandatory to avoid customs quarantine and expensive product recalls.
Ensuring zero dye bleed, high tensile pull holding, and calibrated non-ferrous composition requires rigorous pre-production laboratory batch testing under simulated factory laundry environments.
