5210.31.80 - Of number 69 or higher number

This HTS category, 5210.31.80, specifically covers dyed, plain weave woven cotton fabrics that contain less than 85 percent by weight of cotton, are mixed mainly or solely with man-made fibers, and weigh not more than 200 g/m². The defining characteristic of this subcategory is that the yarn used in the construction of the fabric is of a "number 69 or higher number." This refers to the yarn's fineness, with higher numbers indicating finer yarns.

Distinguishing this category from its siblings, 5210.31.40 and 5210.31.60, is crucial. Those categories cover fabrics made with coarser yarns, specifically "of number 42 or lower number" and "of numbers 43 to 68," respectively. Therefore, 5210.31.80 is reserved for fabrics constructed with significantly finer yarns than those classified under the preceding sibling categories.

Within this category, further subdivisions exist to refine classification based on fabric construction and weave type. The subcategories 5210.31.80.20 and 5210.31.80.90 allow for more specific identification of fabrics such as poplin or broadcloth (under .20) and cheesecloth, lawns, voiles, or batistes (under .90). These distinctions are important for accurately identifying specialized woven cotton fabrics within this defined range of yarn fineness.
