5402.19.30 - Single yarn

This HTS classification, 5402.19.30, specifically covers single yarns of high tenacity nylon or other polyamides that are not put up for retail sale. These yarns are characterized by their exceptional strength relative to their diameter, making them suitable for demanding applications. They are distinct from "sewing thread" which has specific characteristics and packaging for its intended use.

This category differs from its sibling, 5402.19.60.00, which is designated for multiple (folded) or cabled yarns. Therefore, 5402.19.30 applies only to yarns composed of a single strand, not those that have been twisted together or plied. The description "single yarn" is a critical distinguishing factor at this level.

The subcategories under this heading further refine the classification based on the yarn's decitex value, which is a measure of its linear density. Yarns are segregated into those "Not more than 920 decitex" and those "More than 920 decitex." This distinction is important for assessing the physical dimensions and potential applications of the high tenacity nylon yarn.
