5402.19 - Other:

This category, HTS Code 5402.19, encompasses high tenacity yarns of nylon or other polyamides, which are not intended for retail sale and are not sewing thread. The defining characteristic of these yarns is their exceptional tensile strength, making them suitable for demanding applications. This broad classification includes such yarns whether they are textured or untxutured, and covers monofilaments with a decitex of 67 or greater that also meet the high tenacity requirement.

Unlike its sibling category 5402.11, which specifically covers high tenacity yarns of aramids, this category 5402.19 deals with high tenacity yarns derived from nylon or other polyamides. The distinction lies solely in the material composition, with aramids representing a distinct class of high-strength synthetic fibers. Therefore, a yarn's classification under 5402.19 hinges on it being made of nylon or another polyamide, and possessing high tenacity, rather than being an aramid fiber.

Within this classification, further distinctions are made based on the construction of the yarn. Subcategories exist to differentiate between single yarns (5402.19.30), which consist of a single strand, and multiple (folded) or cabled yarns (5402.19.60.00). This subdivision allows for more precise classification based on the structural complexity and intended end-use, reflecting the different physical properties and applications of single versus twisted or cabled yarn constructions.
