Commercial Mass Determination in Regenerated Cellulosic and Synthetic Mixtures
Commercial mass determination reconciles clean dry polymer mass with official regain allowances to secure precise customs compliance and financial settlement.
HS Heading 5402
Tariff Classification
International customs nomenclature assigns a specific six-digit code to synthetic filament yarn that is not textured or prepared for retail sale. Under this classification scheme, hs heading 5402 governs nylon, polyester, and polyamide monofilaments of less than sixty-seven decitex. This harmonized description is used by customs authorities to apply appropriate import duties.
Filament Scope
The category excludes yarn that has been textured or processed with crimp or bulk, which would reclassify it under different codes. Instead, hs heading 5402 covers high-tenacity yarns of nylon and polyester yarns used for industrial sewing thread or tire cord. It also includes untwisted single yarns and yarns with a twist exceeding fifty turns per meter.
These yarns must be made of synthetic polymers rather than natural or artificial regenerated fibers.
Commercial Purpose
Textile importers and garment factories consult this code to determine the origin rules and duty rates for yarn shipments used in apparel manufacturing. If the yarn is incorrectly classified under this heading, the importer may face penalties or delays at the border. Correct application of hs heading 5402 ensures that free-trade agreements are applied accurately based on the fiber’s chemical and physical state.
This code is checked against the laboratory analysis sheet.
Document Verification
Shipping invoices must display the tariff code alongside the raw weight of the shipment. This practice allows customs inspectors to match the physical import with the declared chemical structure of the synthetic filament yarn.
