5512.19.00.10 - Blue denim (225)

This HTS classification, **5512.19.00.10 (Blue denim)**, specifically identifies woven fabrics manufactured from synthetic staple fibers, where polyester staple fibers constitute 85% or more of the total weight. This subcategory is distinguished by its specific characteristic of being "blue denim." This implies a specific weave construction and dyeing process common to denim fabric, recognized by its characteristic twill weave and indigo blue coloration.

This classification differentiates itself from its sibling category, **5512.19.00.05**, which covers "Other" woven fabrics of polyester staple fibers containing 85% or more polyester staple fibers, provided they are *not* blue denim and are *not* made of yarns of different colors (unless it's jacquard weave). Therefore, if a woven fabric meets the general criteria of polyester staple fiber content but is not blue denim, it would fall under the sibling category.

As a leaf node, this classification does not have further subcategories. The defining characteristic for classification under **5512.19.00.10** is the presence of blue denim characteristics. Importers and exporters should ensure that the goods meet the established criteria for blue denim, including its visual appearance, typical weave, and dyeing, to correctly assign this HTS code.
