9902.13.29 - Artificial staple fibers of viscose rayon, not carded, combed or otherwise processed for spinning, such fibers containing between 28 percent and 33 percent by weight of silica, measuring 4.7 decitex in lengths of 60 mm (provided for in subheading 5504.10.00)

This HTS category, 9902.13.29, specifically addresses artificial staple fibers derived from viscose rayon. The defining characteristics for inclusion in this classification are: the fibers are not carded, combed, or otherwise processed for spinning; they contain between 28% and 33% by weight of silica; and they possess a fineness of 4.7 decitex and a length of 60 mm. This precise set of specifications ensures that only very particular types of modified rayon staple fibers are captured under this provision.

Given that this node resides within Chapter 99, which concerns temporary legislation and special provisions, it is important to note that this classification is distinct from the permanent tariff schedule found in other chapters. Unlike the general categories of raw materials or manufactured textile components found elsewhere in the HTS, this subheading applies only to these specifically defined, silica-enhanced viscose rayon staple fibers, likely due to specific trade policy or import restriction considerations.

As a leaf node, HTS 9902.13.29 does not have further subdivisions. Therefore, the classification hinges entirely on meeting the detailed physical and compositional requirements outlined in its description. Classification under this subheading requires careful verification of the silica content (between 28% and 33% by weight), the fiber fineness (4.7 decitex), and the fiber length (60 mm), alongside confirmation that the fibers are indeed artificial staple fibers of viscose rayon and have not undergone further processing for spinning.
