6403.91.60.50 - With pigskin uppers

This HTS classification, 6403.91.60.50, specifically covers footwear designed for men, youths, and boys where the outer sole is constructed from rubber, plastics, leather, or composition leather, and the upper material is predominantly pigskin. These articles fall under the broader category of "Other tennis shoes, basketball shoes, gym shoes, training shoes and the like," signifying their athletic or casual sporting purpose and construction. The key defining characteristic at this level is the exclusive use of pigskin for the shoe's upper.

Distinguishing this category from its sibling, 6403.91.60.60 "Other," is crucial for accurate classification. While both fall under the general "other" subdivisions for athletic-type footwear for men, youths, and boys, the .50 code is precisely for those with pigskin uppers. The sibling category, .60, would encompass similar athletic footwear for the same demographic but made with other types of leather or materials that do not fit the specific pigskin criteria.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, classification under 6403.91.60.50 requires a definitive determination that the footwear meets all preceding criteria: an outer sole of rubber, plastics, leather, or composition leather; an upper primarily of leather; it is "other" footwear (not specifically sport-specific as defined elsewhere); it covers the ankle; and it is intended for men, youths, and boys, with the decisive factor being the pigskin upper construction.
