About HS Code 540310

This category encompasses high tenacity viscose rayon filament yarn, not for retail sale or as sewing thread. The 'high tenacity' characteristic is critical, indicating superior strength and durability compared to standard viscose rayon. This makes it an essential material for demanding industrial applications where robust performance is required. Key uses include tire cords, conveyor belts, hoses, and other technical textiles that require high tensile strength and dimensional stability. Importers are typically manufacturers of these specialized industrial products, while exporters are chemical fiber producers with advanced manufacturing capabilities. Understanding the specific strength ratings and denier is crucial for trade, as these yarns are engineered for precise performance requirements in critical applications.

Products Under This Code

Viscose rayon tire cord yarn, High-strength rayon yarn, Industrial viscose filament, Rayon for technical textiles, Viscose for reinforcement materials, High-tenacity textile yarn

Real World Examples

Common Misclassification

Often confused with 540331 (non-high tenacity viscose rayon yarn) due to the shared material, but the 'high tenacity' characteristic is crucial for correct classification.
