5402.47.90.20 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS category encompasses synthetic monofilament yarn and synthetic multifilament yarn that is either untwisted or has a twist of less than 5 turns per meter. The yarn is not intended for retail sale and falls within the broader classification of synthetic filament yarn. Importantly, this category specifically includes monofilaments with a decitex of less than 67. Examples include yarns used in the manufacturing of technical textiles, industrial fabrics, and certain types of netting, where a low twist is essential for the yarn's properties.

This classification distinguishes itself from its sibling category, 5402.47.90.40, based on the degree of twist in multifilament yarns. While this node covers yarns with a twist of less than 5 turns per meter, the sibling node specifically addresses multifilament yarns with a twist of 5 turns or more per meter. Both categories are for other polyester yarns, but the twist level is the critical determinant for correct classification.

As a leaf node, this category has no further subdivisions. Therefore, the classification hinges entirely on the physical characteristics of the yarn, specifically its material (polyester), its form (monofilament or multifilament), its decitex (for monofilament), and the level of twist for multifilament yarns. Importers and exporters should carefully verify these attributes to ensure accurate reporting for customs purposes.
