OEKO-TEX® STANDARD 100 Certification

Finished Products

• A supplier’s certificate or label may be used if:
  • The product is sourced directly from the certificate holder
  • The product remains unchanged from the certified version
  • The certificate is valid and covers the product
• Alternatively, brands and retailers may certify the product under their own OEKO-TEX® label number to maintain control over labeling and traceability

Components and Materials:

• A supplier’s certificate may be used within the certification process to reduce testing if:
  • The material or component is sourced directly from the certificate holder
  • The certificate is valid and covers the material or component
• Component certification cannot be used for product labeling or marketing claims -  The finished product must be certified to reference OEKO-TEX® or use the label

Using pre-certified components helps:

• Identify and address potential issues early in the supply chain, where chemical decisions are made
• Distribute testing and certification efforts across the supply chain
• Improve supply chain traceability

Requirements
Pre-certified inputs may be used if:

• They are sourced directly from the certificate holder
• The certificate is valid and covers the material or component
• Traceability
  For certificate renewals, upstream certificates must come from direct suppliers. Certificates from second-tier suppliers are only accepted for first certifications and during the 2026 transition year.
• Wet Processing:
  For main materials (over 5% of the product's weight or area), all wet processing steps (e.g. dyeing, printing, finishing) must be certified for renewal. Uncertified wet processes are only accepted for first-time certifications and during the 2026 transition year.
