5402.47.10.20 - Untwisted or with twist of less than 5 turns per meter

This HTS classification, 5402.47.10.20, pertains to specific types of synthetic filament yarn, primarily composed of polyester, that are not intended for retail sale. The defining characteristic for this category is that the yarn is either untwisted or possesses a twist of fewer than 5 turns per meter. Further refinement within this category specifies that the yarn must be wholly of polyester, have a decitex measurement between 75 and 80, and contain exactly 24 filaments. This detailed specification ensures precise identification of yarn meeting these precise physical and material attributes.

The key distinction of this category from its siblings lies in the twist level. While 5402.47.10.20 covers yarns with minimal or no twist (less than 5 turns per meter), its sibling category, 5402.47.10.40, encompasses yarns with a twist of 5 turns or more per meter. This difference in twist is a critical factor for customs classification, influencing the yarn's processing characteristics and potential end uses.

As this is a leaf node, there are no further subcategories within 5402.47.10.20. Classification at this level is therefore definitive, based on the combination of material (wholly polyester), denier (75-80 dtex), filament count (24 filaments), and the specified low twist characteristic. Importers and exporters should carefully verify these specific parameters when classifying goods under this HTS code to ensure accurate customs declarations.
