5210.49 - Other fabrics:

This HTS category, 5210.49, encompasses woven fabrics of cotton that contain less than 85 percent by weight of cotton and are mixed mainly or solely with man-made fibers. These fabrics must weigh not more than 200 g/m². The defining characteristic of this subcategory, "Other," is that the fabrics do not fall under the more specific weave patterns detailed in its sibling categories.

It is crucial to distinguish this "Other" category from its sibling, 5210.41, which specifically covers plain weave fabrics. Therefore, fabrics classified under 5210.49 will not exhibit a plain weave structure. The distinction lies in the construction of the weave itself, where plain weave is characterized by a simple interlacing of warp and weft threads in a direct, alternating pattern.

Within this "Other" category, further subclassification exists to refine the classification based on specific weave types. The subcategories 5210.49.10.00 and 5210.49.20.00 address 3-thread or 4-thread twill, including cross twill, and other satin or twill weaves, respectively. Consequently, any woven fabric meeting the general criteria of 5210.49 but not fitting these more specific twill or satin weave definitions will be categorized under the residual "Other" heading, pending examination of its precise weave structure.
