5515.19.00.10 - Blue denim (225)

This classification, HTS Code 5515.19.00.10, specifically covers blue denim woven fabrics manufactured from polyester staple fibers. These fabrics are characterized by their distinctive blue dye, typically achieved through indigo dyeing, and their twill weave construction, which creates diagonal ribs on the surface. The material is derived from polyester staple fibers, meaning short, discrete lengths of polyester filament spun into yarn before weaving. The "(225)" designation often refers to a specific weight or density within the customs system.

This category is distinguished from its sibling, 5515.19.00.05, by its explicit inclusion of blue denim. The sibling category encompasses other woven fabrics of polyester staple fibers that are *not* blue denim or of jacquard weave, and are also not made from yarns of different colors. Therefore, while both fall under "Other woven fabrics of synthetic staple fibers: Of polyester staple fibers: Other," this specific code isolates the common and distinct product of blue denim.

As this is a leaf node, there are no further subcategories under this HTS code. Classification decisions for this entry will therefore hinge on the definitive presence of blue denim construction made from polyester staple fibers, and adherence to the established weight or density parameters indicated by the "(225)" identifier.
