HS Code for Viscose rayon yarn (high tenacity)

High tenacity viscose rayon yarn is classified under HS code 5403.10. In the context of the Harmonized System, "high tenacity" refers to yarn that meets specific breaking strength requirements defined in the Section XI notes. For viscose rayon, this typically means a tenacity greater than 27 cN/tex. Heading 5403 covers artificial filament yarns, and the first subheading (5403.10) is reserved for high tenacity varieties. These yarns are engineered for high strength and are often used in industrial applications, such as the reinforcement of rubber tires, hoses, or conveyor belts. The classification depends entirely on the physical performance characteristics of the filament. If the yarn does not meet the tenacity threshold, it must be classified under the subheadings for regular tenacity yarn (e.g., 5403.31 or 5403.41). This code applies only to yarn not put up for retail sale and not configured as sewing thread.

Products Included

Common Misclassification

It is often confused with HS code 5403.31 (regular single yarn) if the tenacity is not tested or specified. It may also be misclassified under HS code 5902.20 if it has already been woven into a tire cord fabric. Additionally, synthetic high tenacity yarns (like nylon or polyester) are classified under 5402.11 or 5402.19, so the chemical origin of the fiber must be confirmed as artificial (viscose).
