9902.13.34 - Artificial staple fibers of lyocell, not carded, combed or otherwise processed for spinning, measuring 1.7 or more but not over 3.3 decitex and having a fiber length each measuring 25 mm or more but not over 51 mm and containing 25 percent by weight of kaolin (provided for in subheading 5504.90.00)

This HTS category, 9902.13.34, specifically covers artificial staple fibers made from lyocell. These fibers are characterized by their specific physical properties: they are not carded, combed, or otherwise prepared for spinning, and they fall within a defined range for decitex (1.7 to 3.3) and fiber length (25 mm to 51 mm). A crucial defining characteristic is the inclusion of 25 percent by weight of kaolin, a type of clay, within these fibers.

This classification is distinct from other potential categories within Chapter 99 due to its precise material composition and processing status. Unlike general temporary legislation or other temporary modifications, this code targets a very specific product based on its physical and chemical attributes. It also differentiates itself from broader classifications of artificial staple fibers by its inclusion of kaolin and its specific physical dimensions.

As this is a leaf node within the HTS database, there are no further subdivisions under 9902.13.34. Classification under this code is therefore definitive for lyocell staple fibers meeting all the specified criteria regarding decitex, fiber length, and kaolin content. Any variation in these parameters would necessitate re-evaluation for classification under a different HTS code, potentially within the main chapters of the tariff schedule if the temporary provision does not apply.
