6403.99.90 - Valued over $2.50/pair

This HTS category, 6403.99.90, encompasses footwear that does not fit into more specific classifications within heading 6403. The defining characteristic of this subcategory is its value, specifically for footwear valued at over $2.50 per pair. These are items with outer soles of rubber, plastics, leather, or composition leather, and uppers made of leather, which are not otherwise specified or categorized.

This category is distinguished from its sibling, 6403.99.75, solely by the valuation criterion. While both share the same structural and material requirements for classification under heading 6403, 6403.99.90 specifically targets those items exceeding the $2.50 per pair threshold. This distinction is critical for accurate duty assessment and trade compliance.

Further subdivision within 6403.99.90 addresses specific types of footwear. The subcategories for "House slippers" and "Work footwear" are provided to segregate these distinct functional categories. An "Other" subcategory exists to capture any remaining footwear within this valuation bracket that does not qualify for the more specific house slipper or work footwear classifications.
