5501.19.00.00 - Other

This HTS category, 5501.19.00.00, covers synthetic filament tow of nylon or other polyamides that does not fall under the more specific subcategory of aramids. Filament tow refers to a continuous, untwisted bundle of synthetic filaments that are not yet spun into yarn. These materials are typically produced in large quantities and are intended for subsequent processing into various textile products, such as fabrics, nonwovens, or carpets. The defining characteristic of this category is the material composition – nylon or other polyamides – excluding those specifically classified as aramids.

The primary distinction for this classification lies in the exclusion of aramid filament tow, which is separately classified under HTS 5501.11.00.00. While both are synthetic filament tows made from polyamides, aramid fibers possess exceptional strength, heat resistance, and durability, leading to their distinct classification. Therefore, any nylon or polyamide filament tow that does not exhibit these specific aramid properties would be classified here.

As this is a leaf node, there are no further subdivisions within this category. Classification is determined by the material (nylon or other polyamides) and the form (filament tow), ensuring that it is not a more specialized type of polyamide filament tow like aramids. Importers and exporters should verify the exact composition of their filament tow to ensure accurate classification.
