5404.19.80 - Other

This HTS subcategory, 5404.19.80, encompasses synthetic monofilaments exceeding 67 decitex, where no cross-sectional dimension surpasses 1 millimeter, and synthetic strips with an apparent width not exceeding 5 millimeters, when these are not specifically classified elsewhere. The key defining characteristic is the synthetic origin of the material and the specified physical dimensions.

Within the broader category of "Monofilament: Other," this specific classification serves as a residual grouping for items not designated as racket strings (5404.19.10.00). Therefore, any synthetic monofilament or strip meeting the general criteria but not intended for racket string applications would fall under this purview.

The subsequent subdivisions within 5404.19.80 are determined by the specific synthetic polymer used. These include monofilaments and strips made of nylon or other polyamides (5404.19.80.20), those made of polyesters (5404.19.80.40), and a final grouping for other synthetic materials not falling into the preceding categories (5404.19.80.80). This hierarchical breakdown allows for precise classification based on the fundamental material composition.
