5504.90.00.00 - Other 🖩

This HTS category, 5504.90.00.00, covers man-made staple fibers that are not of viscose rayon, and are also not carded, combed, or otherwise processed for spinning. This means it encompasses a variety of synthetic or regenerated cellulose staple fibers, such as those made from acrylic, polyester, nylon, or other artificial materials, provided they are in a raw or untwisted form. The key criteria for inclusion are the material composition and the absence of specific pre-spinning treatments like carding or combing.

It is important to distinguish this category from its sibling, 5504.10.00.00, which specifically classifies staple fibers of viscose rayon. Therefore, if a man-made staple fiber is derived from viscose rayon, it would fall under the sibling category. This classification, 5504.90.00.00, applies to all other artificial staple fibers that meet the criteria of being not carded, combed, or otherwise processed for spinning, but are not viscose rayon.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification within 5504.90.00.00 is determined by the material composition of the staple fiber and the confirmation that it has not undergone carding, combing, or any other processing preparatory to spinning, and is not of viscose rayon. Practical examples could include loose staple acrylic fibers used in upholstery filling or polyester staple fibers before they are spun into yarn.
