5403.10.30.40 - Multifilament, with twist of 5 turns or more per meter (606) 🖩

This HTS classification, 5403.10.30.40, specifically identifies high-tenacity yarn of viscose rayon that is multifilament and possesses a twist of 5 turns or more per meter. These yarns are characterized by their superior strength and are not intended for direct sale to consumers but rather for further manufacturing processes. The designation as "high tenacity" indicates a yarn with a breaking tenacity exceeding a specified standard, making it suitable for applications requiring durability and resistance to stress.

This category is distinguished from its sibling, 5403.10.30.20, by the degree of twist. While both classify single, multifilament, high-tenacity viscose rayon yarns, 5403.10.30.20 covers untwisted yarns or those with a twist of less than 5 turns per meter. Therefore, the defining characteristic for this specific code is the presence of a twist of 5 turns or more per meter, which impacts the yarn's physical properties and potential end uses.

As this classification is a leaf node, there are no further subcategories. Classification under 5403.10.30.40 is therefore dependent on fulfilling the criteria of being a high-tenacity, multifilament yarn of viscose rayon with a twist of 5 turns or more per meter, and not being put up for retail sale. Examples of such yarns might be those used in the production of industrial fabrics, tire cords, or other technical textiles where enhanced strength and twist are essential.
