6402.91.60.90 - Other

This classification pertains to footwear that does not fit into more specific categories within HTS heading 6402. The defining characteristics are that the footwear possesses outer soles and uppers made of rubber or plastics, and it covers the ankle. The "Other" designation at this level signifies that it is not specifically for men, women, or children, but rather a catch-all for footwear that meets the general criteria but lacks these demographic distinctions.

Distinguishing this category from its siblings, 6402.91.60.30 (For men) and 6402.91.60.60 (For women), is crucial. Those siblings are specifically designated based on the intended wearer's gender. This category, 6402.91.60.90, is for any other footwear that meets the outer sole and upper material requirements, covers the ankle, and is not explicitly classified as for men or women. This often includes unisex footwear or items where a specific gender designation is not readily apparent or applicable.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, the classification hinges on the precise application of the rules for footwear with rubber or plastic soles and uppers that cover the ankle, and are not specifically assigned to men's or women's categories, and are valued at not over $3 per pair. Practical considerations for classification would include examining the design, sizing, and any identifying markings to confirm it does not fall under the more specific sibling categories.
