6404.19.15 - Footwear having uppers of which over 50 percent of the external surface area (including any leather accessories or reinforcements such as those mentioned in note 4(a) to this chapter) is leather

This classification covers footwear where the outer sole is constructed from rubber, plastics, leather, or composition leather, and the upper is primarily made of textile materials. Crucially, within this group, the footwear's upper must consist of over 50 percent leather, considering any leather accessories or reinforcements. This distinguishes it from other textile-upper footwear where leather is a less dominant component of the upper.

This category is differentiated from sibling headings that specify protective footwear (6404.19.20), footwear designed for specific wear over or in place of other shoes, or footwear characterized by open toes/heels, slip-on designs, and the absence of prominent rubber or plastic foxing bands. It represents footwear with textile uppers where leather is the principal material forming more than half of the upper's external surface.

The subcategories within this heading further refine the classification based on the intended wearer. These subdivisions, such as "For men," "For women," and "Other," allow for more granular tracking and statistical reporting of imported or exported footwear based on its design and target market.
