HS Code for High tenacity viscose yarn

High tenacity viscose yarn is classified under HS code 5403.10. This code is specific to artificial filament yarn (as opposed to synthetic filament yarn) that possesses high tenacity. Viscose rayon is an artificial fiber derived from regenerated cellulose, and the "high tenacity" designation requires the yarn to meet a specific strength threshold. According to Note 6 to Section XI, high tenacity yarn of viscose rayon must have a tenacity greater than 27 cN/tex. This yarn is typically not put up for retail sale and is not classified as sewing thread, which would move it to heading 5401. It is primarily used in industrial applications, such as the reinforcement of rubber tires (tire cord) or high-strength industrial fabrics. The distinction between heading 5402 (synthetic) and 5403 (artificial) is fundamental to textile classification, based on the chemical origin of the polymer. Viscose, being a regenerated fiber, always falls under artificial filaments.

Products Included

• High tenacity viscose rayon filament yarn
• Industrial grade viscose filament
• Viscose yarn for tire cord manufacturing
• Multi-filament high tenacity artificial yarn
• Viscose rayon monofilament (less than 67 decitex)

Common Misclassification

A common error is classifying this product under 5402.11, which is for high tenacity yarn of nylon or other polyamides. The difference lies in the material: 5402 is for synthetic filaments (petrochemical based), while 5403 is for artificial filaments (cellulose based). Another misclassification is 5403.31, which covers regular (non-high tenacity) viscose yarn. If the tenacity is 27 cN/tex or less, it must be moved to the regular viscose subheadings. Finally, if the yarn is prepared for retail sale, it must be classified under 5406.

FAQ

What is the HS code for high tenacity viscose yarn?

The HS code for high tenacity viscose rayon filament yarn is 5403.10.

What is the difference between synthetic and artificial yarn?

Synthetic yarns (5402) are made from polymers produced by organic synthesis (like nylon), while artificial yarns (5403) are made from regenerated organic polymers (like viscose rayon from wood pulp).
