6404.19.87 - With uppers of textile material other than vegetable fibers and having outer soles with textile materials having the greatest surface area in contact with the ground, but not taken into account under the terms of additional U.S. note 5 to this chapter

This HTS classification, 6404.19.87, specifically covers footwear featuring uppers constructed from textile materials, excluding vegetable fibers. A defining characteristic is that the outer soles are also made of textile materials, which constitute the largest surface area in contact with the ground. Importantly, these textile outer soles must not fall under the provisions of Additional U.S. Note 5 to Chapter 64, which pertains to certain specific types of footwear constructions.

To distinguish this category from its siblings, 6404.19.82 covers footwear with uppers of *vegetable* fibers, whereas this category strictly mandates non-vegetable textile uppers. The sibling 6404.19.89, designated as "Other," would encompass any footwear meeting the general criteria but not specifically defined by the textile outer sole rule under consideration here. The "Valued over $6.50 but not over $12/pair" refinement indicates a specific price bracket relevant for this import.

Within this classification, further subdivisions exist to capture more specific product types. The subcategory 6404.19.87.15 isolates "House slippers," distinguishing them based on their intended purpose. Following this specific designation, a further "Other" subcategory exists to encompass any remaining footwear that fits the general criteria of 6404.19.87 but does not qualify as house slippers, thus allowing for granular classification within the broader footwear group.
