6402.91.40.50 - Other

This HTS classification, 6402.91.40.50, pertains to a specific type of women's footwear categorized under "Other footwear with outer soles and uppers of rubber or plastics, covering the ankle, other, having uppers of which over 90 percent of the external surface area is rubber or plastics." The key defining characteristic for this subcategory is the material composition of the upper, which must be predominantly (over 90%) rubber or plastic. This excludes footwear with specific constructions like foxing or molded bands overlapping the upper, and certain types of protective footwear with substantial functional stitching and non-molded uppers.

It's important to distinguish this classification from its sibling category, 6402.91.40.40, which specifically covers "Work footwear." While both fall under the broader umbrella of footwear with rubber or plastic uppers and soles covering the ankle, the "Work footwear" designation implies a primary function related to occupational safety or specific labor demands, which is not a criterion for classification under 6402.91.40.50. This current classification is for women's footwear where the over 90% rubber or plastic upper is the primary defining factor, irrespective of a specialized work function.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the classification rests solely on the detailed criteria of material composition and the exclusions noted for the upper's construction, applied specifically to women's footwear that covers the ankle and has predominantly rubber or plastic uppers.
