6504.00.90.15 - Of man-made fibers (659)

This HTS classification covers hats and other headgear that are plaited or constructed by assembling strips of any material. Specifically, this subcategory, 6504.00.90.15, pertains to headgear within this group that are constructed from man-made fibers and have undergone a sewing process. The "659" in the description likely refers to an internal referencing system or a specific grouping within the broader classification of man-made fiber headwear.

Distinguishing this category from its sibling, 6504.00.90.45 (Other), is crucial. While both fall under sewn headgear made from assembled strips, this specific classification is exclusively for items manufactured from man-made fibers. The sibling category would therefore encompass sewn headgear made from other materials not classified as man-made fibers, such as natural fibers or a blend where natural fibers predominate. The sewing method is a key characteristic shared by both, indicating the construction technique rather than the material composition.

As this is a leaf node, there are no further subcategories. The classification is complete at this level, meaning that any headgear meeting the criteria of being plaited or assembled from strips, sewn, and primarily composed of man-made fibers would fall under 6504.00.90.15. Examples would include sewn hats, caps, or other headwear fashioned from materials like polyester, nylon, acrylic, or rayon, which are treated as strips and then sewn together to form the final product.
