5515.99.90.40 - Satin weave or twill weave (617) 🖩

HTS code 5515.99.90.40 specifically classifies other woven fabrics of synthetic staple fibers that are characterized by a satin weave or a twill weave. These fabrics are distinct from those classified under sibling codes such as poplin, broadcloth, sheeting, printcloth, cheesecloth, lawns, voiles, batistes, or duck, which are defined by different weave structures or specific fabric types. The satin weave, known for its lustrous surface and smooth feel achieved through a specific interlacing pattern, and the twill weave, which creates diagonal lines and a more durable fabric, are the defining characteristics for inclusion in this subcategory.

This classification is for woven fabrics made predominantly from synthetic staple fibers, meaning short lengths of synthetic filaments. The "other" designation at higher levels indicates that these fabrics do not fall under more specific categories of synthetic staple fiber fabrics based on their construction or intended use, such as those for apparel or industrial applications that might be enumerated elsewhere in Chapter 55. The inclusion of "(617)" likely refers to an internal reference or statistical code within the HTS system, which may provide further granular detail for reporting and analysis but does not alter the fundamental classification criteria of the weave type.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification hinges entirely on the presence of a satin or twill weave in woven fabrics of synthetic staple fibers that are not otherwise specifically classified. Importers and exporters must carefully examine the fabric's weave structure to ensure accurate classification, distinguishing it from other woven fabric types based on the specific interlacing of threads that creates the fabric's surface appearance and properties.
