9902.13.30 - Artificial staple fibers of viscose rayon, not carded, combed or otherwise processed for spinning, such fibers containing between 28 percent to 33 percent by weight of silica, measuring 3.3 decitex, in lengths of 60 mm (provided for in subheading 5504.10.00)

This HTS code, 9902.13.30, specifically classifies artificial staple fibers made from viscose rayon. These fibers are characterized by their unmanufactured state, meaning they have not undergone carding, combing, or any other processing typically done to prepare them for spinning. A key defining characteristic is their silica content, which must range between 28% and 33% by weight. Furthermore, these fibers are precisely measured at 3.3 decitex and have a uniform length of 60 mm. The parenthetical note indicates that the underlying classification for these fibers, absent the special modification, falls under subheading 5504.10.00.

This specific classification is a temporary modification or special provision within Chapter 99 of the HTS, which deals with temporary legislation and trade agreement modifications. It distinguishes itself from other categories at the root level of the HTS database, such as live animals (Chapters 0101-0105), by its focus on manufactured textile materials. While Chapter 55 deals with man-made staple fibers, this entry under Chapter 99 signifies a particular, temporary import restriction or duty rate applied to these specific rayon staple fibers based on their silica content, decitex, and length.

As a leaf node, HTS 9902.13.30 does not have further subcategories. Its specificity means that any imported artificial staple fibers of viscose rayon meeting all the stipulated physical and compositional criteria (silica content, decitex, length) will be classified directly under this provision, potentially subject to unique tariff rates or quotas dictated by the temporary legislation it represents. This level of detail ensures precise classification for goods that may be subject to specific trade policies.
