6403.99.90.65 - Other

This classification covers women's footwear with outer soles of rubber, plastics, leather, or composition leather, and uppers of leather, where the footwear is not otherwise specifically enumerated. Specifically, these are "other" footwear within the broader category of leather-uppered footwear. The crucial defining characteristic is that these items fall into this "other" designation when they do not fit into more granular subcategories based on material, construction, or specific use.

Distinguishing this category from its sibling, 6403.99.90.55, is paramount. The sibling explicitly designates footwear with pigskin uppers. Therefore, this current classification, 6403.99.90.65, encompasses all other women's leather-uppered footwear not made with pigskin uppers, provided they meet the general criteria of the parent categories. This includes footwear with cowhide, sheepskin, goatskin, or other leathers as the upper material, excluding pigskin.

As this is a leaf node in the HTS structure, there are no further subcategories under 6403.99.90.65. Therefore, practical classification relies on thoroughly examining the parent categories and ensuring that the footwear in question does not fit into any more specific preceding classifications. The value criterion of "valued over $2.50/pair" from the parent level remains a relevant factor for inclusion.
