5514.29.00.30 - Duck (219)

This HTS category, 5514.29.00.30, specifically classifies "Duck" woven fabrics. These fabrics are characterized by containing less than 85% by weight of synthetic staple fibers, with cotton being the primary other component. The fabric's weight must exceed 170 g/m², and it falls under the broader heading of dyed woven fabrics of synthetic staple fibers, mixed mainly or solely with cotton.

Distinguishing this category from its siblings, "Duck" refers to a specific type of durable, plain-weave fabric often used for items like canvas, upholstery, and workwear. It is differentiated from "Poplin or broadcloth" (5514.29.00.10) and "Sheeting" (5514.29.00.20) by its construction and typical end-use, which is generally heavier and more robust. "Satin weave or twill weave" (5514.29.00.40) are distinguished by their distinct weave structures that create a characteristic surface appearance and drape, unlike the plain weave of duck.

As a leaf node, 5514.29.00.30 does not have further subcategories. Therefore, classification within this code relies heavily on accurately identifying the fabric as "Duck" based on its weave, weight, and fiber composition, differentiating it from the other named weaves and general "Other" classifications within the same parent heading. The term "Duck" in this context implies a fabric with a high warp thread count relative to its weft, resulting in a strong, tightly woven material.
