6403.59.30.40 - Other

This HTS category, 6403.59.30.40, covers "Other" footwear specifically constructed using the welting method, featuring outer soles made of leather. This classification applies to men's welted footwear where the upper material is not pigskin, as detailed in the sibling category. The key characteristic defining this subcategory is the welting construction technique, which involves sewing a strip of leather or other material to both the upper and the insole, and then to the outsole, creating a durable and often water-resistant shoe.

Distinguishing this category from its sibling, 6403.59.30.20, is crucial. The sibling specifically addresses footwear with pigskin uppers. Therefore, this "Other" category encompasses all men's welt footwear with leather outer soles that do not utilize pigskin for their uppers, irrespective of the specific type or combination of other leather materials used for the upper construction. This ensures a precise classification based on the primary upper material beyond the defined pigskin exception.

As this classification represents a leaf node within the HTS, there are no further subcategories to introduce. Classification at this level is determined by the combination of the outer sole material (leather), the construction method (welted), the intended wearer (men), and the exclusion of pigskin uppers. Importers and exporters must carefully examine the product's construction and materials to ensure accurate classification under this specific code.
