6403.40.30.30 - With pigskin uppers

This HTS category, 6403.40.30.30, specifically classifies footwear where the outer sole is made of rubber, plastics, leather, or composition leather, and the upper part of the footwear is constructed from leather. Within this broader classification, it further narrows down to footwear that incorporates a protective metal toe-cap and is constructed using the welt method. The defining characteristic of this subcategory is the presence of pigskin as the material for the uppers.

This category is distinguished from its sibling, 6403.40.30.90, by the explicit mention of pigskin for the uppers. While both fall under the umbrella of leather-upper footwear with protective toe caps constructed using the welt method, this specific code provides for a precise material specification that the "Other" category does not. Therefore, footwear classified here must demonstrate pigskin in its upper construction to meet the requirements of this particular HTS code.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification at this level is definitive based on the combination of outer sole material, presence of a protective metal toe-cap, welt construction, and the specific type of leather used for the uppers, which in this instance is pigskin. Examples of goods would include men's or women's work boots or industrial shoes that meet all these material and construction criteria, with the upper being demonstrably made of pigskin.
