5402.19.30.10 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS category, 5402.19.30.10, specifically covers high tenacity yarn of nylon or other polyamides that are in a single yarn format. Crucially, these yarns must have a decitex of 920 or less. The defining characteristic of this classification is that the yarn is either a monofilament or a multifilament yarn with a twist of less than 5 turns per meter. This minimal twist ensures the yarn retains its inherent strength and structure without significant plying.

This classification is distinguished from its sibling, 5402.19.30.30, by the degree of twist. While both fall under "Other single yarn" with a decitex not exceeding 920, this category is for yarns with less than 5 turns per meter. The sibling category is for those multifilament yarns with a twist of 5 turns or more per meter. Therefore, the presence and extent of twisting are the primary distinguishing factors at this level.

As this is a leaf node, there are no further subcategories. The classification concludes at this level based on the material (nylon or other polyamides), form (single yarn), decitex (not more than 920), and the specific twist characteristic (monofilament or multifilament with less than 5 turns per meter). Examples of goods falling under this classification would include high-strength nylon yarns used in applications like industrial ropes, fishing nets, or tire cords where a low twist is essential for optimal performance and strength.
