The OEKO-TEX Standard 100 is a globally recognized label that confirms textiles have been tested for harmful substances and are safe for human health. It applies to all types of textile products -from raw fibers to finished garments - and is widely trusted by manufacturers, brands, and consumers.

The certification ensures that every part of the product, including threads, buttons, and labels, meets strict limit values for more than 1,000 harmful chemicals. The tests are based on globally standardized criteria and updated at least once a year.

Products are evaluated under one of four product classes, depending on their intended use:

• Class I: For babies and toddlers up to 3 years (most stringent)

• Class II: Products with direct skin contact (e.g. bedding, underwear)

• Class III: Products without direct skin contact (e.g. jackets)

• Class IV: Decorative items (e.g. upholstery, curtains)

Textile articles can be certified using two testing programs:
Annex 4, which focuses on protecting human health, and Annex 6, which includes additional environmental considerations such as substances used in production that may affect ecosystems but not necessarily human health.

Other key features of the standard include:

• Compliance with major international regulations like REACH (Annex XVII & XIV), US CPSIA (lead), and the EU POPs Regulation

• Certification valid for one year, with required on-site audits by OEKO-TEX institutes

• Acceptance of pre-certified components, which can reduce testing time and costs

• Optional certification for recycled materials, footwear, special articles (e.g. prams, bags), and PPE such as military uniforms and chemical protective clothing

STANDARD 100 also supports transparency and trust. All valid certificates can be verified publicly through the OEKO-TEX Label Check, and certified products are part of a global sourcing network of over 35,000 companies.

The standard is developed and managed by OEKO-TEX, a global association of 17 independent research and testing institutes in Europe and Japan. Since 1992, the organization has worked to promote safety and sustainability in the textile and leather industry through science-based standards. Its mission is to enable responsible decisions and protect natural resources while supporting traceability and transparency across supply chains.
