5402.19.30.70 - Multifilament, with twist of 5 turns or more per meter (606)

This HTS classification covers high tenacity yarn of nylon or other polyamides, specifically single yarns that are multifilament in nature. The defining characteristic of this category is a twist of 5 turns or more per meter. This level of twist is a crucial factor in distinguishing these yarns from others, indicating a manufacturing process that enhances their strength and durability. These yarns are not intended for retail sale and are typically used as industrial materials rather than consumer goods.

The primary distinction from its sibling category, 5402.19.30.50, lies in the degree of twist. While both categories concern high tenacity nylon or polyamide multifilament yarns exceeding 920 decitex, this specific classification applies only when the yarn exhibits a twist of 5 turns or more per meter. The sibling category, conversely, encompasses untwisted yarn or multifilament yarn with a twist of less than 5 turns per meter. This difference in twist directly impacts the yarn's physical properties and its suitability for various industrial applications.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification criteria, therefore, focus on the specific characteristics of the yarn itself: its material (nylon or other polyamides), its form (multifilament single yarn), its tenacity (high tenacity), its decitex value (more than 920), and importantly, its twist level (5 turns or more per meter). Importers and exporters must carefully verify these attributes to ensure accurate classification.
