As a Brand, you can now validate material composition in inbound TC transactions (B5) and production transactions (B2) more accurately when composite fibers are declared using their component materials. Composite fibers like Viscose, Lyocell, Modal, and Rayon are often represented as combinations such as Recycled Cotton and Wood. This enhancement introduces composite fiber alias mapping, so these combinations are recognized during material composition validations. This ensures valid certificates pass even when the composite fiber name itself is not listed.


Key Benefits

  • Accurate Validation: Composite fibers are correctly validated when declared through their underlying component materials.
  • Simplified Submissions: Suppliers can upload certificates without adjusting fiber names to match brand master data.


This enhancement strengthens material composition validation by recognizing composite fiber equivalents through accepted component combinations. It reduces avoidable validation failures and supports more accurate and consistent traceability for both Brands and Suppliers. Reach out to TrusTrace support if you want to add the material name aliases.
