5514.19.90.40 - Satin weave or twill weave (617)

This HTS classification covers woven fabrics of synthetic staple fibers that contain less than 85% by weight of synthetic fibers, mixed mainly or solely with cotton, and exceed 170 grams per square meter in weight. Specifically, this category encompasses fabrics not classified under other specific weave types within the same parent heading. This includes, but is not limited to, fabrics exhibiting satin weave or twill weave structures that do not fall into the more precisely defined categories of poplin, broadcloth, sheeting, or duck.

The distinction of this category lies in its residual nature for certain woven fabric types. While other sibling categories at this level (5514.19.90.10, 5514.19.90.20, 5514.19.90.30) detail specific weaves like poplin, broadcloth, sheeting, and duck, this classification applies to other satin or twill weaves that don't conform to those narrower definitions. The key distinguishing factors remain the fabric's composition, weight, and the presence of a satin or twill weave structure when it doesn't fit into the more enumerated categories.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification relies solely on accurately identifying the fabric's material composition, weight, and whether it exhibits a satin or twill weave while not fitting the descriptions of the other specific weave categories at this level. Importers should ensure that the fabric's characteristics align with the general requirements of woven fabrics of synthetic staple fibers mixed with cotton, exceeding 170 g/m², and that it is not specifically classifiable under the poplin, broadcloth, sheeting, or duck descriptions.
