5402.44.00.40 - Other

HTS Code 5402.44.00.40, described as "Other," falls under the broader category of elastomeric synthetic filament yarn. This specific classification applies to single yarns that are either untwisted or have a twist not exceeding 50 turns per meter, and are made from synthetic filaments. Crucially, these yarns are not put up for retail sale and are distinct from synthetic monofilaments.

This subcategory distinguishes itself from its sibling, 5402.44.00.05 ("Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter"), by encompassing a wider range of elastomeric yarns. While the sibling focuses on very low twist or untwisted monofilaments and multifilaments, 5402.44.00.40 includes elastomeric filament yarns with a twist between 5 and 50 turns per meter. The "Other" designation signifies that it captures elastomeric yarns that do not meet the specific twist requirements or structural characteristics of the preceding categories within the 5402.44.00.00 heading.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification under 5402.44.00.40 hinges on the precise identification of the material as synthetic filament yarn, its classification as elastomeric, its form as single yarn, and its twist rate falling within the specified range, while also ensuring it is not put up for retail sale and does not qualify as monofilament. Examples could include spun-elastane yarns with a moderate twist for industrial applications in apparel or technical textiles.
