6405.90.90 - Other

This HTS category, 6405.90.90, encompasses "Other" footwear not specifically provided for in the preceding headings of Chapter 64. It serves as a residual category for footwear that does not fit into more specific classifications based on material composition or intended use. This includes a wide array of footwear types that are not explicitly defined by their upper or sole materials, or their specific functional purpose as outlined in other 6405 subheadings.

This classification differs from its sibling category, 6405.90.20.00, which is exclusively for disposable footwear designed for single use. The goods classified under 6405.90.90 are generally intended for multiple uses, even if their construction might be less robust than more specialized footwear. The broad nature of this "Other" designation means that careful consideration of the specific construction and intended application of the footwear is crucial for accurate classification.

The subcategories within 6405.90.90 provide further refinement for specific types of footwear. 6405.90.90.30 is designated for footwear specifically designed for infants, as further described in statistical note 2 to this chapter. This distinction recognizes the unique design considerations and sizing requirements for infant footwear. The remaining subcategory, 6405.90.90.60, captures all other "other" footwear that does not meet the criteria for infant footwear, thus continuing the residual nature of the parent category at a more granular level.
