5512.99.00.35 - Duck (219)

HTS Code 5512.99.00.35 classifies woven fabrics of synthetic staple fibers, where synthetic staple fibers constitute 85% or more by weight of the total content. Specifically, this subheading pertains to fabrics described as "Duck." Duck fabric is a strong, plain-woven cotton or linen fabric, but in the context of this synthetic staple fiber chapter, it refers to synthetic equivalents exhibiting similar characteristics of weight, weave, and durability.

This category is distinguished from its sibling categories primarily by the specific fabric construction and common usage associated with "duck." While other subheadings at this level cover specific weaves like poplin, sheeting, printcloth, cheesecloth, lawns, voiles, batistes, or satin/twill weaves, this classification targets fabrics that are typically heavier and more robust, often used for applications requiring durability such as canvas goods, awnings, or industrial textiles. The "duck" designation implies a particular density and strength profile beyond that of finer weaves.

As a leaf node within the HTS, this subheading does not have further subdivisions. Classification under 5512.99.00.35 hinges on the fabric meeting the 85% synthetic staple fiber threshold and possessing the characteristic weave and physical properties commonly associated with "duck" fabrics, as opposed to the more specific weave types or fabric names listed under its sibling categories. Importers must ensure that the imported fabric's construction and intended use align with the established definition of duck fabric to warrant this classification.
