6402.99.31.73 - For infants, as described in statistical note 2 to this chapter

This HTS classification, 6402.99.31.73, specifically covers footwear for infants. The defining characteristic of this category is that the footwear must have outer soles and uppers made entirely of rubber or plastics, or where the external surface area of the uppers is predominantly (over 90%) rubber or plastic. This excludes footwear with specific features like a foxing or foxing-like band overlapping the upper, or those designed as protective footwear for harsh weather or chemical exposure.

Distinguishing this classification from its siblings, "For men" and "For women," is the primary intended wearer. While the material and construction requirements are the same as the broader 6402.99 category, this subcategory is exclusively for footwear designed to fit infants. The term "infants" is further defined by statistical note 2 to Chapter 64, which provides specific sizing or developmental criteria that a customs broker or importer must consult to ensure accurate classification.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification under 6402.99.31.73 relies on a direct assessment of the footwear's suitability for infants, alongside the stipulated material composition and the absence of exclusionary features detailed in the parent categories. Importers should carefully review statistical note 2 for precise guidance on what constitutes "infant" footwear within this context.
