6402.99.31 - Other

This HTS category, 6402.99.31, encompasses "Other" footwear falling under the broader classification of other footwear with outer soles and uppers of rubber or plastics. Specifically, it covers footwear where the external surface area of the uppers is comprised of over 90% rubber or plastics. It is important to note the exclusions mentioned in the parent category's description, such as footwear with a foxing or foxing-like band, and footwear designed as protective wear against water, oil, grease, chemicals, or inclement weather.

This classification is distinct from its sibling category, 6402.99.27, which specifically designates sandals and similar footwear of plastics produced in one piece by molding. While both fall under "other footwear with outer soles and uppers of rubber or plastics," 6402.99.31 applies to a wider range of footwear types that do not meet the specific criteria of being molded, one-piece sandals.

The subcategories under 6402.99.31 further refine the classification based on the intended use or specific type of footwear. These include house slippers (6402.99.31.10), which are generally designed for indoor comfort, and athletic footwear such as tennis shoes, basketball shoes, gym shoes, and training shoes (6402.99.31.15). The existence of an "Other" subcategory indicates that there are still other types of footwear within the 90% rubber or plastic upper criterion that do not fit into the more specific subcategories, requiring further detailed examination for accurate classification.
