5504.10.00.00 - Of viscose rayon 🖩

This HTS classification, 5504.10.00.00, specifically covers artificial staple fibers derived from viscose rayon that have not undergone further processing such as carding or combing. Viscose rayon staple fibers are characterized by their cellulose-based origin, manufactured through a chemical regeneration process. These fibers are typically produced in relatively short, uniform lengths, making them suitable for spinning into yarns for textiles and other applications, but they are not yet prepared for direct spinning.

This category is distinguished from its sibling, 5504.90.00.00, which encompasses all other artificial staple fibers not of viscose rayon. Therefore, classification under 5504.10.00.00 hinges on the precise material composition, confirming the fiber is a regenerated cellulose product manufactured via the viscose process, and that it remains in a state prior to carding, combing, or other preparatory treatments for spinning. The "Of viscose rayon" designation is the primary determinant, excluding synthetic staple fibers or staple fibers made from other regenerated cellulosic materials.

As a leaf node, this category does not have further subcategories. Classification within 5504.10.00.00 is definitive once the material is identified as viscose rayon staple fiber and it meets the condition of not being carded, combed, or otherwise processed for spinning. This level of specificity ensures accurate tariff application for unspun viscose rayon staple fibers entering trade.
