6403.91.60.90 - Other

This category, HTS 6403.91.60.90, classifies "Other" footwear that has outer soles of rubber, plastics, leather, or composition leather, and uppers of leather, and which covers the ankle. The "Other" designation at this level indicates that these are not specific types of footwear previously enumerated within the broader subheadings. The key determinative factor for inclusion here is the presence of leather uppers and an outsole constructed from the specified materials, coupled with a design that extends above the wearer's ankle.

This classification is distinct from its sibling category, "For men," because it is not restricted by gender. While footwear for men, youths, and boys with similar construction (leather uppers, specified outer soles, covering the ankle) would fall under the "For men" sibling, this particular "Other" category is intended for footwear of this construction that is not specifically designated for males, encompassing options for women, girls, and unisex styles.

As a leaf node in the HTS database, this subcategory does not have further subdivisions. Therefore, classification under 6403.91.60.90 is determined by the exclusion of the item from more specific categories and its adherence to the material and construction requirements outlined in its parent and grandparent headings, specifically: footwear with leather uppers and outsoles of rubber, plastics, leather, or composition leather, that covers the ankle, and is not otherwise specified. Examples could include certain types of women's boots or unisex hiking boots not fitting into more defined subheadings.
