5403.39.90.20 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS classification, 5403.39.90.20, pertains to artificial filament yarn that is not intended for retail sale. Specifically, it encompasses monofilament yarn and multifilament yarn characterized by a low twist, defined as fewer than 5 turns per meter. These yarns are typically used in industrial applications such as manufacturing textiles, fishing nets, and other technical fabrics, rather than for direct consumer use.

The key distinction of this category lies in the twist applied to multifilament yarn. It is differentiated from its sibling category, 5403.39.90.40, which covers multifilament yarn with a twist of 5 turns or more per meter. Therefore, the degree of twisting is the determining factor in assigning goods to one of these closely related classifications.

As this HTS code represents a leaf node, there are no further subdivisions. Classification within 5403.39.90.20 is determined by the material being artificial filament, its form as monofilament or low-twist multifilament, and its presentation (not put up for retail sale). Importers and exporters should carefully assess the physical characteristics of the yarn, particularly the twist count for multifilament types, to ensure accurate classification.
