6405.20 - With uppers of textile materials:

This HTS category, 6405.20, encompasses footwear where the upper portion is constructed from textile materials. This broad classification applies to a wide range of shoes, boots, slippers, and similar items where fabric forms the primary external component of the upper. The textile materials can include woven fabrics, knitted fabrics, felt, and other man-made or natural fibers.

Distinguishing this category from its siblings is crucial for accurate classification. Category 6405.10 specifically addresses footwear with uppers made of leather or composition leather. Therefore, if the upper is primarily composed of textile materials, it would fall under 6405.20, not 6405.10, regardless of the sole material. Category 6405.90 serves as a catch-all for "other" footwear not specifically classified elsewhere within Chapter 64, but 6405.20 provides a more specific placement for textile-upper footwear.

Within 6405.20, further subcategories exist to refine the classification based on specific material compositions or constructions. These include footwear with uppers made of vegetable fibers (6405.20.30), footwear with both soles and uppers of wool felt (6405.20.60), and a residual "other" category (6405.20.90) for textile-upper footwear that does not meet the criteria for the more specific subheadings. This tiered structure allows for precise identification based on the dominant materials and manufacturing methods.
