The mandatory fibre composition disclosure requirements for EU-bound South African textiles. How to structure percentage-by-weight data in JSON-LD format for machine-readable compliance.
The EU ESPR Textile Delegated Act requires that every garment's DPP include a complete fibre composition declaration by percentage weight. This means listing every fibre present in the product at or above 1% by weight, using the standardised EU fibre nomenclature (e.g., 'cotton', 'polyester', 'elastane' — not trade names). For blended fabrics, each component fibre must be listed separately with its percentage. For garments with multiple components (e.g., a jacket with a shell, lining, and padding), each component must be declared separately. The data must be structured in JSON-LD format using the schema.org Product type with a 'material' property.
From mid-2027, the EU additionally requires that any recycled content claim be verified with supplier documentation. A garment claiming '30% recycled polyester' must include a SHA-256 hashed supplier invoice or Global Recycled Standard (GRS) certificate proving the recycled content. The National DPP Registry's onboarding flow includes a dedicated recycled content verification step where manufacturers upload their GRS certificates, which are immediately hashed client-side and linked to the product's DPP. This creates a forensically verifiable recycled content claim — not just a marketing statement.
South Africa's Gqeberha/Nelson Mandela Bay textile cluster is the registry's launch pilot. The cluster produces cotton garments, mohair knitwear, and blended performance fabrics. South African mohair — produced primarily in the Karoo — is a globally recognised premium fibre with a unique provenance story. The registry creates a Mohair Provenance Passport that links the fibre's origin farm (GPS-tagged, CIPC-verified) to the finished garment's DPP. This is the kind of origin-linked transparency that EU premium retailers are actively demanding and that South African manufacturers can uniquely provide.
