5501.30.00 - Acrylic or modacrylic
Sub-classifications
-
5501 3000 10Containing 92 percent or more by weight of acrylonitrile units with filaments numbering fewer than 70,000 (+/-2000) with filament diameter 1.59 decitex (plus or minus 0.027) or less, or in a separable tow construction capable of being separated into tows of 70,000 (+/-2000) or fewer with filament diameter 1.59 decitex (plus or minus 0.027) or less. 🖩
Overview
This HTS category, 5501.30.00, specifically classifies synthetic filament tow made from acrylic or modacrylic fibers. Filament tow refers to a large, untwisted bundle of continuous filaments, typically used as a raw material for the production of spun yarns and other textile articles. The defining characteristic of this classification is the material composition, requiring the tow to be predominantly acrylic or modacrylic.
This category is distinguished from its siblings by the specific polymer used. While other categories within 5501 cover filament tow of nylon or other polyamides (5501.10), polyesters (5501.20), polypropylene (5501.40), and other synthetic materials (5501.90), this particular heading is solely dedicated to acrylic and modacrylic filament tow. This distinction is crucial for accurate customs declarations, as the end-use and processing of these different synthetic materials can vary significantly.
Within this classification, two subcategories exist to further refine the classification based on specific technical specifications. Subcategory 5501.30.00.10 covers acrylic filament tow with very precise filament counts and diameters, often indicative of specialized applications. The broader category, 5501.30.00.90, encompasses all other acrylic or modacrylic filament tow that does not meet the stringent requirements of the more specific subcategory, ensuring comprehensive coverage for this type of synthetic material.
