5513.23.01.21 - Satin weave or twill weave (617)

This HTS category, 5513.23.01.21, specifically classifies dyed woven fabrics of polyester staple fibers, weighing no more than 170 g/m², and containing less than 85% polyester staple fiber mixed mainly or solely with cotton. The defining characteristic of this subcategory is its weave construction, encompassing satin weave or twill weave fabrics that fall within these specified fiber content and weight limitations. These fabrics are typically used in apparel, home furnishings, and other textile applications where the specified weave and fiber composition are critical for aesthetic or functional properties.

This classification is distinguished from its siblings by its precise weave. While 5513.23.01.41 covers Oxford cloth, and 5513.23.01.91 encompasses "Other" woven fabrics, 5513.23.01.21 is reserved for those specifically identified as being constructed in a satin weave or a twill weave. The distinction is purely based on the interlacing pattern of the warp and weft yarns, a key determinant in fabric appearance, drape, and durability.

As a leaf node, this category does not have further subcategories. Classification at this level is final, based on the combination of the fabric's material composition (polyester staple fiber mixed with cotton), weight, dyeing status, and its specific weave construction (satin or twill). Importers and exporters must carefully examine the fabric's technical specifications to ensure accurate classification under this precise code.
