5210.19 - Other fabrics:

This HTS category, 5210.19, encompasses unbleached woven fabrics of cotton that contain less than 85 percent by weight of cotton, mixed mainly or solely with man-made fibers, and weigh no more than 200 g/m². The defining characteristic here is that the fabric's weave construction is not specifically a plain weave, distinguishing it from its sibling category 5210.11.

Within this category, the classification further refines based on the specific weave structure. The subcategories are designed to capture different textural and structural properties that affect the fabric's appearance and potential end uses. For instance, 5210.19.10.00 specifically addresses 3-thread or 4-thread twill weaves, including cross twill, which are recognizable by their diagonal rib pattern.

The remaining subdivisions under 5210.19 cater to other weave types. Subcategory 5210.19.20 covers fabrics with a satin or twill weave that does not fall under the specific 3-thread or 4-thread twill designation. This ensures that a comprehensive range of woven cotton-blend fabrics, beyond the plain weave and specific twills, are accurately classified based on their distinct weave constructions.
