5402.19.30.30 - Multifilament, with twist of 5 turns or more per meter (606)

This HTS code classification applies to synthetic multifilament yarn, specifically those composed of nylon or other polyamides. A key defining characteristic of yarn under this heading is its construction: it must have a twist of 5 turns or more per meter. This high degree of twist contributes to the yarn's strength and durability, making it suitable for specialized industrial applications. The yarn is not put up for retail sale, indicating it is intended for further manufacturing processes.

This specific classification is distinguished from its sibling category, 5402.19.30.10, by the twist applied. While both cover high tenacity yarns of nylon or other polyamides, this heading exclusively covers multifilament yarns with a significant twist (5 turns or more per meter). The sibling category, conversely, includes monofilament, untwisted multifilament, or multifilament with a twist of less than 5 turns per meter. Therefore, the amount and direction of twist are crucial for accurate classification.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification decisions at this level hinge on the precise physical characteristics of the yarn, primarily its multifilament construction and the specific twist rate. Importers and exporters should ensure that the yarn in question meets the criteria of being a high tenacity nylon or polyamide multifilament yarn with a twist of 5 turns or more per meter to correctly assign it to this HTS code.
