6402.91.20.00 - Valued over $3 but not over $6.50/pair

This HTS classification, 6402.91.20.00, specifically covers footwear with outer soles and uppers made of rubber or plastics that extend above the ankle, and which incorporate a protective metal toe-cap. These are further categorized as "other" footwear within their broader groups. The crucial defining characteristic for this particular subcategory is its value, which must be over $3 but not over $6.50 per pair.

This category is distinguished from its siblings by this precise valuation range. For instance, 6402.91.16.00 covers similar footwear valued at $3 or less per pair, while 6402.91.26.00 and 6402.91.30.00 address footwear valued at higher price points. Therefore, the economic value of the item is the primary determinant for distinguishing between these closely related classifications.

As this is a leaf node within the HTS database, there are no further subcategories branching from 6402.91.20.00. This means that once the criteria of outer sole and upper material (rubber or plastic), covering the ankle, presence of a protective metal toe-cap, and the specified value range are met, the classification is definitively established at this level. Practical application will focus on verifying these physical characteristics and the per-pair valuation through invoices or other import documentation.
