6303.99.00.10 - Of artificial fibers (666)

This HTS subcategory, 6303.99.00.10, specifically classifies curtains, drapes, and interior blinds that are *of artificial fibers* and are not covered by more specific preceding headings within the "Other textile materials" category. This designation encompasses a wide range of window coverings manufactured from man-made fibers such as polyester, nylon, acrylic, and rayon, provided they do not fall under more specialized classifications based on weave, finish, or construction. The key distinguishing factor here is the primary material composition being synthetic.

While the parent category encompasses various made-up textile articles, this subcategory's focus on "artificial fibers" differentiates it from items made of natural fibers like cotton or linen, or those specifically designated as mixed textile articles if the artificial fiber component is not predominant. The classification hinges on the identification and predominance of artificial fibers in the construction of the textile article.

As this is a leaf node, there are no further subdivisions within this specific HTS code. Therefore, the practical application of this classification relies on the accurate identification of the textile material as artificial fiber and its use in the form of curtains, drapes, or interior blinds, meeting the general criteria of the preceding headings within Chapter 63.
