6403.59.90.30 - With pigskin uppers

This HTS category, 6403.59.90.30, specifically classifies footwear with outer soles of leather and uppers made from pigskin. These are typically formal or semi-formal shoes designed for women, falling under the broader classification of footwear for "other persons" and then further specified for women. The key defining characteristic for this subcategory is the material of the upper.

This classification is distinct from its sibling category, 6403.59.90.45, which is designated for "Other" footwear under the same parent heading. While both fall under "Other footwear with outer soles of leather" and then "Other" and "For women," the crucial differentiator here is the explicit mention of pigskin uppers. The sibling category would encompass women's leather-soled footwear with uppers made from materials *other than* pigskin, such as cowhide, goatskin, or other leathers not specifically itemized.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus is on the precise material of the upper. Classification decisions under this code hinge on the accurate identification of pigskin as the primary material composing the upper portion of the footwear, provided the outer sole is confirmed to be leather. Any deviation in the upper material would necessitate consideration of the "Other" sibling category or different HTS headings entirely.
