5515.29.00.35 - Duck (219)

This category, HTS 5515.29.00.35, specifically classifies woven fabrics made from synthetic staple fibers, excluding those meticulously detailed in preceding subcategories. The "Duck" designation signifies a particular type of durable, plain-weave fabric, often characterized by its sturdiness and distinct weave structure, which lends itself to applications requiring resilience.

Distinguishing this classification from its siblings, such as poplin, broadcloth, sheeting, and printcloth, lies in the specific weave construction and typical end-uses. While those categories refer to fabrics with finer weaves or more common apparel applications, "Duck" fabric generally implies a heavier, more robust textile often employed in workwear, upholstery, awnings, or other industrial and outdoor uses where its inherent strength is paramount. The exclusion of satin or twill weaves further refines this category to plain-weave constructions that define "duck."

As this is a leaf node within the HTS, there are no further subcategories. The classification is complete at this level, with the term "Duck" serving as the definitive descriptor for these woven synthetic staple fiber fabrics, differentiating them based on their specific construction and common utility.
