5210.11 - Plain weave:

This HTS category, 5210.11, specifically covers plain weave cotton fabrics that are unbleached. These fabrics contain less than 85 percent by weight of cotton, with man-made fibers being the primary admixture. The weight of these textiles does not exceed 200 g/m². The "unbleached" designation is crucial, indicating that the fabric has not undergone any chemical or mechanical bleaching processes, retaining its natural coloration from the raw fibers.

Category 5210.11 is distinguished from its sibling, 5210.19, which covers "other fabrics" within the same broad classification of woven cotton containing less than 85% cotton and weighing not more than 200 g/m². While 5210.11 is restricted to plain weave constructions, 5210.19 would encompass woven fabrics of cotton with other weaves, such as twill, satin, or dobby weaves, that meet the material composition and weight criteria.

The subcategories within 5210.11, namely 5210.11.40, 5210.11.60, and 5210.11.80, further refine the classification based on the "number" of the yarn used in the fabric. This "number" typically refers to yarn count or fineness, a critical determinant in the physical characteristics and potential end-uses of textile articles. Importers and exporters will need to consult specific yarn count specifications to correctly assign goods to the appropriate subdivision under 5210.11.
