5209.21.00.90 - Plain weave duck (219)

This HTS classification, 5209.21.00.90, pertains to plain weave cotton fabrics that are bleached and weigh more than 200 grams per square meter, with cotton comprising at least 85% of their weight. Specifically, it encompasses "duck" fabrics within this category. Duck is a robust, plain-weave cotton textile, often characterized by its durability and relatively heavy weight, making it suitable for applications such as canvas, tents, awnings, and workwear.

Within the "Bleached: Plain weave" level, this category is distinguished from its sibling, 5209.21.00.20, which covers poplin or broadcloth. While both are bleached, plain weave cotton fabrics exceeding 200 g/m², poplin and broadcloth are typically characterized by a finer weave and often a smoother finish compared to the coarser, heavier construction of duck. The distinction lies primarily in the yarn count, weave density, and the resulting textural and functional properties.

As this is a leaf node in the HTS, there are no further subcategories under 5209.21.00.90. Therefore, classification under this code is definitive for bleached, plain weave cotton fabrics exceeding 200 g/m² that meet the 85% cotton content requirement and are identified as "duck" in nature, based on their construction and intended use. The "plain weave" designation signifies a simple over-under interlacing of warp and weft yarns.
