5211.20.21.90 - Plain weave duck (219)

This HTS classification covers woven fabrics of cotton that contain less than 85 percent by weight of cotton, predominantly blended with man-made fibers, and weigh more than 200 grams per square meter. Specifically, it applies to bleached fabrics exhibiting a plain weave construction. This category is distinct from its sibling "Poplin or broadcloth" (5211.20.21.20), which also features a plain weave but refers to fabrics with a finer yarn count and smoother finish. The "Sheeting" sibling, though not fully defined here, would generally encompass coarser, heavier plain weave fabrics used for items like bed linens.

As this is a leaf node, there are no further subcategories within this specific classification. Therefore, the distinction and focus remain on the precise characteristics defined: a plain weave structure within bleached cotton blends exceeding 200 g/m². Practical classification relies on verifying the cotton content percentage, the primary man-made fiber content, the weight per square meter, the bleaching status, and the weave type.
