5210.11.40 - Of number 42 or lower number

This HTS category encompasses unbleached plain weave cotton fabrics weighing not more than 200 g/m², where the cotton component is less than 85% by weight and is mixed mainly or solely with man-made fibers. The defining characteristic for this specific subcategory is the "number" of the yarn, referring to its linear density. Goods classified here fall under the umbrella of woven fabrics of cotton, as per Section XI of the Harmonized Tariff Schedule.

This classification is distinguished from its siblings by the yarn count. Specifically, 5210.11.40 applies to fabrics woven with yarns designated as "number 42 or lower number." This implies a coarser yarn count compared to the finer yarns found in sibling categories 5210.11.60 (numbers 43 to 68) and 5210.11.80 (number 69 or higher). Accurate determination of the yarn count is crucial for correct classification within this group.

Within this category, further subdivisions exist to account for specific fabric constructions. The subcategories provide more granular classification based on weave type and intended application. For instance, 5210.11.40.20 covers poplin or broadcloth, known for their fine, even texture and crisp hand. 5210.11.40.40 relates to sheeting fabrics, typically used for bedding, while 5210.11.40.90 encompasses cheesecloth, a loosely woven fabric often used for straining or medical applications. These subdivisions reflect variations in weave structure that influence the fabric's properties and uses.
