6403.51.30.71 - Other 🖩

This category specifically classifies footwear where the outer sole is constructed from rubber, plastics, leather, or composition leather, and the upper is made of leather. Furthermore, these articles must cover the ankle and are not otherwise specified within the broader "other footwear with outer soles of leather" heading. The crucial defining characteristic here is the construction method, identifying "welt footwear" as a distinct method of shoe assembly that falls under this classification.

This designation distinguishes these welted shoes from other types of footwear that might also have leather uppers and leather outer soles but are constructed differently or serve a different purpose. For instance, while the sibling category "For women" addresses gender-specific footwear, this node focuses on the manufacturing technique of welt construction, irrespective of the intended wearer.

As a leaf node, this HTS code does not have further subdivisions. Therefore, classification within this category relies on confirming that the footwear meets all preceding criteria: leather upper, leather outer sole, covering the ankle, and specifically being constructed using the welt method. Examples would include durable work boots or traditional dress shoes assembled with a stitched welt that attaches the upper to the sole and midsole, creating a robust and often resoleable shoe.
