5512.91.00.50 - Duck (219) 🖩

HTS code 5512.91.00.50, described as "Duck" within the context of woven fabrics of synthetic staple fibers containing 85 percent or more by weight of synthetic staple fibers, specifically pertains to a distinct type of fabric characterized by its durable weave. Duck fabric, in this classification, refers to a heavy, plain-woven fabric, often with a high thread count, that is known for its strength and robustness. This makes it suitable for a wide range of applications, from workwear and upholstery to tents and sails.

This classification distinguishes itself from sibling categories by its specific weave construction. For instance, while categories like "Poplin or broadcloth" (5512.91.00.10) or "Sheeting" (5512.91.00.20) also fall under woven fabrics of synthetic staple fibers, they generally denote different weave structures and often lighter weights. Similarly, "Printcloth" (5512.91.00.30) implies fabrics designed for printing, and "Cheesecloth; lawns, voiles or batistes" (5512.91.00.40) represent much finer and more delicate weaves. "Duck" fabric's inherent toughness and characteristic weave set it apart.

As this HTS code represents a leaf node, there are no further subcategories under 5512.91.00.50. Therefore, the focus for classification purposes remains on confirming that the fabric meets the criteria of containing 85 percent or more by weight of synthetic staple fibers and exhibiting the physical characteristics and weave structure of "duck" fabric. The absence of subcategories means that further differentiation relies solely on the precise identification of the material composition and the distinct weaving pattern.
