9902.13.25 - Staple fibers of viscose rayon, not carded, combed or otherwise processed for spinning, measuring 0.90 or more but not over 1.30 decitex and having a fiber length each measuring 20 mm or more but not over 150 mm (provided for in subheading 5504.10.00)

This HTS category, 9902.13.25, specifically addresses staple fibers derived from viscose rayon. These fibers are characterized by their physical dimensions: a decitex measurement of 0.90 or greater but not exceeding 1.30, and a fiber length ranging from 20 mm to 150 mm. Crucially, these fibers are not yet processed for spinning, meaning they are in a raw or semi-processed state, lacking the carding, combing, or other preparatory treatments typically applied before yarn formation. This classification is situated within Chapter 99, which pertains to temporary legislation, trade agreement modifications, and import restrictions.

While other HTS codes within Chapter 99 may address various temporary measures or special provisions, this particular subheading targets a very specific type of rayon staple fiber. Its distinction lies in the precise range of decitex and fiber length, alongside the absence of advanced processing for spinning. It is important to note that this code is a "leaf node," meaning it does not have further subdivisions. Therefore, classification under 9902.13.25 hinges directly on meeting all the stipulated physical criteria for the viscose rayon staple fibers. The underlying provision, subheading 5504.10.00, refers to man-made staple fibers of synthetic filaments, providing further context for the material's origin.
