9902.13.38 - Acrylic staple fibers, carded, combed or otherwise processed for spinning, containing by weight 92 percent or more of polyacrylonitrile, not more than 0.01 percent of zinc and 2 percent or more but not over 8 percent of water, dyed, with an average decitex of 5.0 to 5.6 (provided for in subheading 5506.30.00)

This HTS classification, 9902.13.38, specifically addresses acrylic staple fibers that have undergone processing for spinning, such as carding or combing. The key defining characteristics for goods falling under this provision are their composition: they must contain at least 92 percent by weight of polyacrylonitrile, a very low level of zinc (not exceeding 0.01 percent), and a specific water content range of 2 to 8 percent. Furthermore, these fibers must be dyed and possess an average decitex between 5.0 and 5.6.

This temporary classification is distinguished from broader categories within Chapter 99 by its highly specific product criteria, particularly the detailed percentages of polyacrylonitrile, zinc, and water, as well as the average decitex. While other items within Chapter 99 may also be subject to temporary import restrictions or modifications, this particular code is reserved for these very precisely defined acrylic staple fibers. It is important to note that the primary classification for these types of fibers, absent these specific temporary provisions, would typically be found under subheading 5506.30.00.

As this is a leaf node within the HTS database, there are no further subcategories under 9902.13.38. Therefore, classification into this specific code hinges entirely on meeting all the enumerated technical and physical requirements detailed in its description. Any deviation in composition, processing, dyeing status, or decitex from the defined parameters would necessitate re-evaluation and classification under a different HTS code, potentially the primary provision indicated in the description or another applicable temporary or permanent chapter.
