Tariff Classification
Customs coding for synthetic filament yarn that is not textured or prepared for retail sale ensures correct duty assessment and trade tracking at international borders. This category of HS 5403 applies to high-tenacity yarn of nylon or polyester that is imported for industrial textile production. Customs brokers use this specific code to classify flat, untextured filament yarn shipped from synthetic fiber mills.
The classification ceases to apply if the yarn is put up in retail packages or has undergone a texturizing process.
Trade Code
Specific duty rates and import restrictions are applied based on the subheadings of this commodity classification. For example, high-tenacity polyester yarn for tire cords or conveyor belts is separated from regular weaving yarns under HS 5403. This distinction ensures that industrial raw materials are taxed correctly during customs clearance.
Import Documentation
Compliance with customs regulations requires accurate fiber composition declarations and trade documents. When a mill imports synthetic filament yarn, the commercial invoice must match the requirements of HS 5403 to avoid shipping delays and penalties at the border. The documentation must also show that the yarn is untextured and has not been packaged for consumer retail sale.
Weaving Application
Raw filament yarns imported under this code are usually sent to weaving or knitting mills for bulk fabric production. They provide the strength and uniformity required for technical fabrics and apparel linings.
