6403.51.90.15 - With pigskin uppers

This HTS classification covers footwear with outer soles of leather and uppers of leather, specifically designed for women, that cover the ankle, and are not further specified by material composition beyond the pigskin upper. These are generally considered dress or casual boots and booties for female wearers, where the defining characteristic is the presence of pigskin as the primary upper material.

This subcategory distinguishes itself from its sibling, 6403.51.90.30 "Other," by its explicit mention of pigskin uppers. While both fall under the broader category of women's leather footwear covering the ankle, this specific code isolates those instances where pigskin is the designated upper material, implying unique properties or market segmentation that warrant separate tariff treatment.

As this node is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is determined by the confluence of an outer sole of leather, an upper of pigskin, the footwear's characteristic of covering the ankle, and its intended use for women. This means that any footwear meeting these specific criteria will be classified under 6403.51.90.15.
