5501.30.00.90 - Other 🖩

This HTS category, 5501.30.00.90, covers synthetic filament tow of acrylic or modacrylic fibers that does not meet the specific criteria of the preceding sibling category. Essentially, it acts as a residual classification for acrylic or modacrylic filament tow, encompassing a broad range of products within this material type and form. The defining characteristic is that it is a continuous strand of synthetic fibers, intended for further processing, but not specifically enumerated in the more detailed classifications.

The distinction between this category and its sibling, 5501.30.00.10, lies in precise quantitative and qualitative specifications. The sibling category narrowly defines tow based on the percentage of acrylonitrile, the number of filaments, and filament diameter, or a specific separable tow construction. Therefore, any acrylic or modacrylic filament tow that does not precisely match these intricate specifications, such as tow with a different filament count, broader filament diameter, or an acrylonitrile content outside the specified range, will fall under this "Other" category.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 5501.30.00.90 is contingent upon accurately determining that the product is indeed acrylic or modacrylic synthetic filament tow and that it does not qualify for the more granular classification provided by its sibling. Importers and exporters should carefully examine the technical specifications of their acrylic or modacrylic filament tow to ensure correct classification and avoid potential customs discrepancies.
