6405.90.90.30 - For infants, as described in statistical note 2 to this chapter

This HTS category, 6405.90.90.30, specifically classifies "Other footwear" designed for infants, as further defined by statistical note 2 to Chapter 64. These are footwear items for very young children that do not fall into more specific headings within Chapter 64, such as those made of rubber, plastics, textile materials, or leather that have distinct construction or design features. The "infant" designation is crucial for proper classification, implying a size and construction suitable for babies and very young toddlers.

The sibling category, 6405.90.90.60, also falls under "Other footwear" and "Other," but it encompasses footwear that is *not* specifically designated for infants. Therefore, the key differentiator between 6405.90.90.30 and its sibling is the intended end-user: this category is exclusively for infant footwear, while the sibling covers all other "other footwear" not fitting the infant criteria.

As this is a leaf node in the HTS hierarchy, there are no further subcategories to introduce. Classification within this code relies on ensuring the footwear meets the general description of "other footwear" and specifically meets the criteria outlined in statistical note 2 concerning its suitability for infants, along with the absence of features that would place it in a more specific heading.
