6303.92.20.10 - Window curtains (including drapes) and window valances (666)

This HTS category specifically covers window curtains, drapes, and window valances that are constructed from synthetic fibers and do not fall under any more specific subheading. The term "other" indicates that this is a residual category for synthetic textile window coverings not otherwise enumerated. This includes a wide range of decorative and functional window treatments made entirely or predominantly of synthetic materials such as polyester, nylon, acrylic, or rayon.

Given that this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the primary focus for classification under 6303.92.20.10 is to ensure the item meets the criteria of being a window curtain, drape, or valance and is made of synthetic fibers. The absence of specific distinctions at this level means any synthetic textile product fitting the general description of a window covering, and not classified elsewhere, will reside here. Practical classification relies on identifying the finished nature of the product, its intended use as a window covering, and the material composition.
