5210.31.80.20 - Poplin or broadcloth (314)

This HTS category, 5210.31.80.20, specifically classifies dyed, plain weave woven fabrics of cotton, containing less than 85 percent by weight of cotton and mixed mainly or solely with man-made fibers, weighing not more than 200 g/m², that are identified as "Poplin or broadcloth". These fabrics are characterized by their relatively fine weave and a smooth surface, often achieved through a balanced construction where warp and weft yarns are of similar size and count. Poplin, in particular, is known for its crisp feel and slight horizontal rib effect due to a higher warp yarn count.

The distinguishing feature of this classification lies in the specific fabric type "Poplin or broadcloth" at this granular level. While its sibling category, 5210.31.80.90, covers other lightweight, dyed, plain weave cotton blends such as cheesecloth, lawns, voiles, and batistes, those fabrics typically have a more open construction, lighter weight, or a different feel and drape compared to the denser, more structured nature of poplin and broadcloth. The "Poplin or broadcloth" designation provides a crucial identifier for these specific types of plain weave constructions within the broader category of dyed cotton blends.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, classification into 5210.31.80.20 depends on meeting all the preceding criteria: being a woven fabric of cotton, containing less than 85% cotton and primarily man-made fibers, weighing no more than 200 g/m², dyed, of a plain weave, and of number 69 or higher, with the specific identification as poplin or broadcloth being the final determinant.
