6403.91.90 - For other persons

This HTS category, 6403.91.90, encompasses footwear with outer soles made of rubber, plastics, leather, or composition leather, and uppers of leather, that cover the ankle. It specifically pertains to "other persons," meaning footwear not designated for men, youths, or boys. The key criteria for inclusion are the material composition of the sole and upper, the height of the footwear (covering the ankle), and its intended wearer demographic.

Distinguishing this category from its sibling, 6403.91.60 ("For men, youths and boys"), hinges solely on the target wearer. While both share the same construction and ankle-covering attributes, 6403.91.90 is for all other individuals, including women, girls, and potentially unisex designs not explicitly categorized for males. This differentiation is crucial for accurate tariff application based on intended consumer segments.

The subcategories under 6403.91.90 further refine classification. "Work footwear" (6403.91.90.15) applies to shoes designed for occupational safety or specific demanding work environments. The subsequent "Other" subdivision (often implied or further detailed in subsequent levels) covers all remaining ankle-covering leather footwear for persons not otherwise specified, including casual, athletic, or fashion footwear that meets the preceding criteria.
