6303.19.21.10 - Of artificial fibers (666)

This HTS category, 6303.19.21.10, specifically covers curtains, drapes, and interior blinds, as well as curtain or bed valances, that are knitted or crocheted and made from textile materials other than cotton or synthetic fibers. The "of artificial fibers (666)" designation indicates that the primary textile component is derived from manufactured fibers, such as rayon or nylon, and distinguishes it from natural fibers or purely synthetic fibers.

This subcategory differentiates itself from its sibling, 6303.19.21.20 ("Other"), by its explicit material composition. While the sibling category would encompass knitted or crocheted window treatments made from a broader range of "other textile materials" that are not specifically classified as artificial fibers, this node is precisely for those constructed from artificial fibers. The context of "knitted or crocheted" is crucial, as it excludes woven or other non-knitted/crocheted textile constructions of similar purpose.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification ends here. The practical application of this code relies on correctly identifying the knitted or crocheted construction and the presence of artificial fibers as the predominant material in the finished article, such as window curtains, shower curtains, or decorative valances intended for interior use.
