5512.19.00.40 - Duck (219)

This HTS category, 5512.19.00.40, specifically covers "Duck" woven fabrics that are composed of 85 percent or more by weight of synthetic staple fibers, with the synthetic staple fibers being polyester. The term "duck" in textile terminology refers to a plain weave fabric, typically made from cotton or synthetic fibers, characterized by its strong, durable construction and often a slightly coarse texture. This fabric is commonly used in applications requiring robustness, such as workwear, upholstery, bags, and awnings.

Distinguishing this category from its siblings, the "Other" designation indicates that "Duck" fabrics are not specifically enumerated under more descriptive terms like "Poplin or broadcloth," "Printcloth," "Cheesecloth; lawns, voiles or batistes," or those defined by specific weave structures like "Satin weave or twill weave." Therefore, if a woven fabric meets the criteria of containing 85 percent or more polyester staple fibers and exhibits the characteristics of duck weave (a firm, tightly woven plain weave), it falls under this specific classification, provided it doesn't fit a more narrowly defined sibling.

As this is a leaf node in the HTS, there are no further subcategories. Classification within this code relies on the fulfillment of the primary material composition (85% or more polyester staple fibers) and the specific fabric construction identified as "duck" weave. Customs officials will examine the physical characteristics and weave pattern to confirm its inclusion under this heading.
