5211.20.21.50 - Napped (313)

This HTS classification applies to woven fabrics of cotton that have undergone a napping process. The defining characteristic here is the napping, which creates a raised, fuzzy surface on one or both sides of the fabric. These fabrics must contain less than 85 percent by weight of cotton, with the remaining weight predominantly comprised of man-made fibers. Furthermore, they are distinguished by their weight, exceeding 200 grams per square meter, and their construction being of a plain weave, specifically within the sheeting category.

This category is differentiated from its sibling, "Not napped," by the presence of the napping treatment. While both categories fall under "Bleached" woven fabrics of cotton mixed with man-made fibers weighing over 200 g/m², the napped variant possesses a distinct textural quality imparted by the finishing process, which is absent in the "Not napped" category.

As this is a leaf node, there are no further subcategories to explore. Therefore, classification within 5211.20.21.50 is definitive once the criteria of cotton content, primary fiber composition, weight, weave, bleaching status, sheeting type, and the presence of napping are met. Practical examples might include durable cotton-blend flannel or brushed cotton sheeting used for bedding or apparel where a soft, raised surface is desired.
