How to verify and declare recycled content in textile DPPs. The Global Recycled Standard (GRS) integration, supplier invoice hashing, and the EU's mandatory recycled content thresholds for 2030.
The EU Strategy for Sustainable and Circular Textiles sets mandatory minimum recycled content targets for textile products sold on the EU market. By 2030, all textile products must contain a minimum percentage of recycled fibres, with the specific threshold varying by product category. For polyester garments, the target is 50% recycled polyester by 2030. For cotton blends, the target is 20% recycled cotton. These targets are not yet mandatory for the 2027 DPP deadline, but the DPP must declare the current recycled content percentage — creating the baseline data that will be used to enforce the 2030 targets.
The Global Recycled Standard (GRS), administered by Textile Exchange, is the primary certification for recycled content claims in textiles. GRS certification covers the entire supply chain from recycled input material to final product, verifying that the recycled content percentage is accurate and that the recycling process meets environmental and social standards. The National DPP Registry integrates with the Textile Exchange database to verify GRS certificate numbers at the point of onboarding. Manufacturers upload their GRS certificates, which are SHA-256 hashed client-side and linked to the product DPP. EU buyers can verify GRS status via the registry's public verification API.
For manufacturers who source recycled fibres from suppliers without GRS certification, the National DPP Registry accepts SHA-256 hashed supplier invoices as supporting documentation for recycled content claims. The invoice must specify the recycled content percentage, the recycling process used, and the origin of the post-consumer or post-industrial waste. The hash is stored in the D1 ledger alongside the product DPP, creating a forensically verifiable audit trail. EU customs agents can request the original invoice from the registry's secure vault if they need to verify the claim during a compliance inspection.
