5408.22.10.00 - Of cuprammonium rayon (618)

This HTS category, 5408.22.10.00, specifically classifies dyed woven fabrics that are composed of 85 percent or more by weight of artificial filament or strip, and are made from cuprammonium rayon. Cuprammonium rayon, also known as cupro, is a type of regenerated cellulose fiber known for its silk-like drape and sheen. Fabrics classified here are finished through a dyeing process, meaning the color is imparted to the fabric after weaving.

This classification distinguishes itself from its sibling category, 5408.22.90, by its specific material content. While both fall under "Other woven fabrics, containing 85 percent or more by weight of artificial filament or strip or the like: Dyed:", this particular code requires the artificial filament to be cuprammonium rayon. The sibling category would encompass other types of dyed woven fabrics meeting the 85% artificial filament criteria but made from different artificial filament yarns.

As this HTS code is a leaf node, it does not have further subcategories. Therefore, the primary focus for classification within 5408.22.10.00 is the precise identification of the fabric as being woven from cuprammonium rayon and having undergone a dyeing process. Classification hinges on the material composition and the dyeing treatment, ensuring accurate reporting for customs purposes.
