6403.19.40.30 - With pigskin uppers

This HTS category, 6403.19.40.30, specifically classifies sports footwear with outer soles made from rubber, plastics, leather, or composition leather, and uppers constructed from leather. The defining characteristic for this sub-classification is the presence of pigskin as the primary material for the shoe's upper. This designation is critical for accurate customs declarations, ensuring compliance with import and export regulations.

Within the broader context of "Other" sports footwear for men, youths, and boys, this category is distinguished from its sibling, 6403.19.40.90 ("Other"), by the explicit identification of pigskin in the upper. While the sibling category would encompass all other types of leather or composite uppers not specifically pigskin, this code isolates footwear where pigskin is the discernible upper material, regardless of its specific tanning or finishing process.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification stops at this specific descriptor. Practical application of this code requires careful inspection of the footwear to confirm the presence and prominence of pigskin in its upper construction. Examples would include athletic shoes, hiking boots, or specialized sports footwear where pigskin is the chosen material for the shoe's exterior, providing specific characteristics like flexibility or durability.
