Classification Category
Synthetic staple fibre mixed with man-made filaments serves to distinguish hs 5515.13 as a specific tariff heading for goods containing polyester mixed with wool or fine animal hair. Customs authorities assign this code to textile materials where the polyester fibre content exceeds half the total weight by composition.
Processing Verification
Manufacturers verify the material designation during the technical audit of yarn spinning logs and fabric construction sheets. Documentation requires a breakdown of fibre percentages to confirm that polyester staple fibres meet the threshold against the weight of the sheep wool or mohair present in the blend. The laboratory analysis happens before the final shipping declaration to ensure correct tax assessment at the port of entry.
Market Application
Commercial trade in suiting and trousers relies on this classification to manage import duties for blended textile goods. Suppliers provide testing reports to garment factories that substantiate the presence of polyester alongside traditional animal fibres. Quality inspectors use these figures to reconcile the bill of materials with the declared weight ratios found in the final roll.
Duty Assessment
Government agencies apply this numerical tag to establish the tariff rate for items moving across international borders. High volumes of polyester mixed with animal fibres trigger consistent revenue collection practices under this specific classification. The classification remains constant until a legislative change alters the criteria for synthetic blends in international trade agreements.
