5210.19.40 - Of number 42 or lower number

This HTS category, 5210.19.40, specifically classifies unbleached woven fabrics of cotton 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 for this particular sub-classification is that these fabrics are constructed with yarns of a specific fineness, namely those of number 42 or lower in cotton count. This indicates a relatively coarser thread construction for the woven fabric.

This classification is distinct from its siblings, 5210.19.60 and 5210.19.80, based on the yarn number. While all fabrics in the 5210.19 category fall under the broader scope of "Other fabrics" within the unbleached, cotton-containing blends weighing no more than 200 g/m², the sub-number differentiates based on the coarseness of the threads used. 5210.19.60 covers fabrics made from yarns of numbers 43 to 68, and 5210.19.80 is for fabrics utilizing yarns of number 69 or higher, indicating progressively finer threads.

Within category 5210.19.40, two subcategories exist to further refine the classification. "Oxford cloth (227)" is a specific weave that meets the criteria of this category, often characterized by its basketweave structure and slightly irregular texture. The "Other (220)" subcategory serves as a residual category for any other unbleached woven cotton-blend fabrics that are not specifically identified as Oxford cloth but otherwise meet the yarn count and weight requirements of 5210.19.40.
