5515.99.90.35 - Duck (219)

This HTS category, 5515.99.90.35, specifically designates woven fabrics of synthetic staple fibers that do not fall under more precise subcategories within the "Other woven fabrics of synthetic staple fibers" group. The "Duck" designation refers to a plain weave fabric, typically with a warp count that is twice the filling count, resulting in a dense, sturdy material. This classification is applied when the fabric's construction or weave pattern does not align with the specific patterns or constructions defined in other sibling categories.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, categories like "Poplin or broadcloth" (5515.99.90.15), "Sheeting" (5515.99.90.20), and "Printcloth" (5515.99.90.25) describe specific weave structures and thread counts. Similarly, "Cheesecloth; lawns, voiles or batistes" (5515.99.90.30) and "Satin weave or twill weave" (5515.99.90.40) refer to distinct weave types or fabric constructions. When a synthetic staple fiber woven fabric does not fit the detailed descriptions of these other categories, it is classified under the "Other: Other" designation.

As a leaf node, HTS code 5515.99.90.35 has no further subcategories. Therefore, classification into this specific code relies entirely on the exclusion from more narrowly defined categories at the same level. Importers and exporters must carefully examine the fabric's construction, weave, thread count, and intended use to ensure it does not meet the criteria for any of the other listed woven fabrics of synthetic staple fibers before assigning it to this residual category.
