5514.30.32.10 - Blue denim (225)

This HTS classification, 5514.30.32.10, specifically covers blue denim fabrics that are constructed using a 3-thread or 4-thread twill weave, including cross twill. These fabrics are characterized by their composition, containing less than 85 percent by weight of synthetic staple fibers, predominantly polyester, mixed mainly or solely with cotton. The weight of these fabrics must exceed 170 g/m². The "blue denim" designation refers to the traditional indigo dye used for the warp threads, while the weft threads are typically white or a lighter shade, creating the characteristic color contrast of denim.

This category is distinguished from its sibling, 5514.30.32.15 (Other denim), by the precise weave construction. While both fall under the broader "Denim" heading within woven fabrics of synthetic staple fibers, this specific classification requires a 3-thread or 4-thread twill weave. The sibling category would encompass denim fabrics not meeting this specific twill requirement, potentially including other twill variations or different weaving structures. Therefore, the precise number of warp threads used in the twill is a critical differentiating factor.

As this node represents a leaf node within the HTS, there are no further subcategories. Classification at this level is definitive based on the described characteristics: the material composition (synthetic staple fibers mixed with cotton), the weight threshold, the specific weave (3-thread or 4-thread twill, including cross twill), and the color specification (blue denim). Importers and exporters must ensure all these criteria are met for accurate classification under this code.
