6406.10.90.60 - Other (899)

This classification covers uppers and parts of uppers for footwear, excluding stiffeners. Specifically, this subcategory, "Other (899)," pertains to textile materials other than cotton, wool, fine animal hair, or man-made fibers. This includes textile uppers and their components that do not fit into the more specific categories like those made of wool, cashmere, or synthetic filaments.

The distinction between this category and its siblings lies in the material composition of the textile. While 6406.10.90.20 focuses on wool or fine animal hair, and 6406.10.90.40 is for man-made fibers, this category acts as a residual for other textile materials. Examples might include uppers made from linen, silk, or blends of textiles not predominantly falling into the other specified categories. The classification relies on identifying the primary textile constituent if a blend is present.

As this is a leaf node within the HTS structure, there are no further subcategories under this specific code. Therefore, precise classification hinges on accurately determining that the textile material of the footwear upper does not align with the definitions of wool, fine animal hair, or man-made fibers, and ensuring it meets the broader criteria for textile uppers as defined in Chapter 64.
