6405.20.90 - Other

Category 6405.20.90 encompasses "Other" footwear with uppers of textile materials, excluding those specifically classified under 6405.20.30 (uppers of vegetable fibers) and 6405.20.60 (soles and uppers of wool felt). This broad category captures a wide array of footwear where the primary upper material is textile-based, but which do not fit into the more precise sibling categories based on specific fiber types or construction. Examples could include athletic shoes with textile uppers, casual footwear, or even certain types of work boots where the upper is predominantly made from woven or knitted textile.

The distinction from sibling categories is crucial for accurate classification. Category 6405.20.30 is reserved for footwear where the textile upper is derived from vegetable fibers such as cotton, linen, or jute. Similarly, 6405.20.60 is specifically for footwear constructed entirely from wool felt for both its sole and upper. Therefore, 6405.20.90 serves as a residual category for textile-upper footwear that does not meet these more specific material or construction criteria.

Within this category, further subdivisions exist to refine classification. Category 6405.20.90.15 specifically covers house slippers. The remaining "Other" subcategory, which is itself a placeholder for further potential subdivisions, would encompass all other textile-upper footwear not designated as house slippers and not falling under the aforementioned sibling categories. This layered approach allows for granular control over the classification of diverse footwear items.
