5209.11.00.90 - Plain weave duck (219)

This HTS category, 5209.11.00.90, specifically classifies unbleached, plain weave woven fabrics of cotton that constitute 85% or more of the total weight and weigh over 200 g/m². The term "duck" in its description refers to a specific type of plain weave fabric known for its durability and often characterized by a balanced weave (equal number of warp and weft threads per unit of length). These fabrics are typically used in heavy-duty applications such as canvas, tents, sails, and workwear due to their substantial weight and robust construction.

This classification differentiates itself from its sibling categories by excluding specific types of plain weave fabrics. While 5209.11.00.20 covers poplin or broadcloth, which are also plain weaves but generally lighter and with a finer thread count, and the "Sheeting" category (which would be a sibling if fully detailed) typically refers to lighter, more common bedding fabrics, this "duck" category is reserved for the heavier, more utilitarian plain weave cotton fabrics exceeding the specified weight threshold.

As this node is a leaf node, it does not have further subcategories. Therefore, classification within 5209.11.00.90 is determined by the definitive criteria of being an unbleached, plain weave cotton fabric, containing at least 85% cotton by weight, and weighing more than 200 grams per square meter, with the specific designation of "duck" fabric. This ensures that robust, heavy-duty cotton canvas-like materials are distinctly identified for customs purposes.
