5402.20.30.70 - Multifilament, with twist of 5 turns or more per meter (606)

This HTS category, 5402.20.30.70, specifically classifies high-tenacity polyester single yarn that is multifilament and exhibits a twist of 5 turns or more per meter. These yarns are characterized by their exceptional tensile strength, making them suitable for demanding applications. The "multifilament" designation indicates the yarn is composed of multiple individual filaments twisted together, contributing to its overall strength. The critical criterion for inclusion in this subcategory is the presence of a significant twist level, a physical characteristic that enhances the yarn's structural integrity and performance in various industrial uses.

This classification distinguishes itself from its sibling category, 5402.20.30.50, by the yarn's twist. The sibling category covers monofilament or multifilament yarn with either no twist or a twist of less than 5 turns per meter. Therefore, the presence of a twist of 5 turns or more per meter is the definitive factor in directing classification to 5402.20.30.70. This distinction is important for customs purposes as the manufacturing process and resultant properties differ based on the degree of twist.

As a leaf node, this category does not have further subcategories. The classification is determined by the confluence of material (high tenacity polyester), structure (single yarn, multifilament), decitex (more than 920), and the specific twist parameter (5 turns or more per meter). Examples of goods that would fall under this classification include yarns used in the production of industrial fabrics, ropes, tire cord, and other materials where high tensile strength and durability are paramount.
