6403.99.75 - Valued not over $2.50/pair

This HTS category, 6403.99.75, encompasses footwear with outer soles of rubber, plastics, leather, or composition leather and uppers of leather, which are not specifically classified elsewhere within heading 6403. The "other footwear" and "other" designations at this level indicate a residual classification for items that do not fit into more specific subheadings. Crucially, this particular code is designated for footwear valued not over $2.50 per pair, forming a distinct price-based criterion for classification.

This category is distinguished from its sibling, 6403.99.90, solely by the declared value of the footwear. While both share the same material composition and general form, 6403.99.75 applies to lower-value items, whereas 6403.99.90 covers those valued at more than $2.50 per pair. This value threshold is a critical determinant in correctly classifying these otherwise similar types of footwear.

Within this classification, further subdivisions exist to refine the categorization of this specific type of footwear. The subcategories, such as "House slippers" (6403.99.75.15), provide more granular distinctions based on the intended use and design of the footwear. The existence of an "Other" subcategory at the next level acknowledges that even after these specific subdivisions, there may be remaining items that meet the general criteria of this code but do not fit into the more precisely defined categories.
