OEKO-TEX STANDARD 100 is a product safety standard: it limits substances that could be harmful to human skin — regulated chemicals, pH, formaldehyde, certain dyes, and more. It tests the finished article (or its components), not the farm or the factory. That makes it different from organic or recycled standards, which are about how the material was produced.
| Class | Use |
|---|---|
| Class I | Baby articles — strictest limits |
| Class II | Items worn close to skin (most apparel) |
| Class III | Outerwear, not directly against skin |
| Class IV | Decoration and furnishing materials |
Every valid certificate carries a number you can check at the OEKO-TEX label check. The number must resolve to the exact legal entity named on the cert — see our verification guide for why the name match is the whole test.
We hold OEKO-TEX and list it with our other certificates on the compliance page.
No. It is a harmful-substance limit on the finished article. An OEKO-TEX certified cloth can be entirely virgin synthetic.
Most adult apparel worn against the skin is Class II; baby items are Class I. The class follows the end use, not the fibre.
