5515.11.00.40 - Satin weave or twill weave (617)

This HTS code, 5515.11.00.40, specifically classifies other woven fabrics of synthetic staple fibers, primarily polyester, that are mixed mainly or solely with viscose rayon staple fibers and are constructed in a satin weave or a twill weave. These fabrics are characterized by their distinct weaves, which affect their drape, texture, and appearance. The satin weave typically results in a smooth, lustrous surface with a tendency to be pliable, while the twill weave creates diagonal ribs and is generally more durable and less prone to wrinkling.

Distinguishing this category from its siblings, 5515.11.00.40 is differentiated by its specific weave construction. While other sibling categories like poplin, sheeting, or duck also fall under woven fabrics of polyester and viscose rayon, their classification is based on different weave structures or fabric densities. For instance, poplin and sheeting have a plain weave, printcloth is a lightweight plain weave fabric, and duck is characterized by a strong, tightly woven plain weave. Cheesecloth, lawns, voiles, and batistes are typically lighter and have more open weaves, while this category is specifically for satin and twill weaves.

As this node represents a leaf node in the HTS classification, there are no further subcategories. Therefore, classification under 5515.11.00.40 relies on accurately identifying the material composition (predominantly polyester staple fibers mixed with viscose rayon staple fibers) and confirming the presence of a satin or twill weave structure. If the fabric does not exhibit these specific weave types or has a different primary fiber content, it would be classified elsewhere within Chapter 55 or other relevant chapters of the Harmonized Tariff Schedule.
