5516.91.00.50 - Duck (219)

This HTS classification, 5516.91.00.50, specifically designates "Duck" woven fabrics made from artificial staple fibers that are unbleached or bleached. Duck fabric is characterized by its plain weave and typically high thread count, resulting in a strong, durable material. It is often used in applications requiring robustness, such as canvas, workwear, and certain types of upholstery.

Distinguishing this category from its siblings, "Duck" is differentiated by its specific weave structure and common end-use applications, whereas other siblings like poplin, sheeting, printcloth, and cheesecloth represent different weave structures and typical fabric constructions within the broader "woven fabrics of artificial staple fibers, other, unbleached or bleached" umbrella. For instance, poplin and sheeting are generally lighter and smoother, while printcloth is designed for ease of printing.

As a leaf node in the HTS database, this category represents a specific and finalized classification for duck woven fabrics of artificial staple fibers. Therefore, there are no further subcategories to introduce. Classification within this code hinges on confirming the fabric's composition of artificial staple fibers, its unbleached or bleached state, its plain weave construction, and its identification as "duck" based on its characteristic density and durability.
