6404.19.57.90 - Other

This HTS subcategory, 6404.19.57.90, encompasses footwear where the outer sole is made of rubber or plastics, and the upper is constructed from textile materials other than vegetable fibers. Crucially, these items are characterized by outer soles that incorporate textile materials, with these textile sole components presenting the greatest surface area in contact with the ground. However, this classification specifically excludes footwear that would be accounted for under Additional U.S. Note 5 of Chapter 64, implying specific technical definitions for the textile sole construction that are not met here.

To distinguish this "Other" category from its siblings, note that 6404.19.57.30 covers similar footwear designated "For men," while 6404.19.57.60 applies to footwear "For women." This "Other" category, therefore, serves as a residual classification for footwear meeting the material and sole construction criteria but not specifically intended for men or women as per the established subcategories.

As this is a leaf node in the HTS classification system, there are no further subcategories. The classification is definitive at this level, meaning all footwear meeting the detailed criteria of textile uppers, rubber or plastic soles with a greatest ground contact surface of textile, and not falling under Additional U.S. Note 5, and which is not specifically for men or women, will be classified under 6404.19.57.90. Examples might include certain athletic shoes or casual footwear designed for unisex use or where gender designation is not clearly defined by the footwear's construction or marketing.
