9902.13.28 - Viscose rayon staple fibers having a decitex of less than 5.0 and a trilobal multi-limbed cross-section, the limbs having a length-to-width aspect ratio of at least 2:1, suitable for use in producing goods of heading 9619 (provided for in subheading 5504.10.00)

This specific HTS code, 9902.13.28, designates special provisions for imported viscose rayon staple fibers that meet very precise technical specifications. These fibers are characterized by a decitex of less than 5.0 and a distinctive trilobal multi-limbed cross-section. Furthermore, the limbs of this cross-section must exhibit a length-to-width aspect ratio of at least 2:1. Crucially, these fibers are intended and suitable for the production of goods classified under heading 9619, which typically includes absorbent articles such as sanitary towels, tampons, and diapers.

Distinguishing this category from other HTS classifications is paramount. Unlike general provisions for staple fibers or rayon fibers found elsewhere in the tariff schedule (such as subheading 5504.10.00 which is explicitly referenced as the underlying classification), this 9902 code signifies a temporary measure or specific restriction, likely related to trade agreements or other legislative actions. It focuses on a highly specialized type of fiber with defined physical attributes and a singular intended end-use, setting it apart from broader categories that might encompass a wider range of rayon staple fibers.

As this is a leaf node within the HTS database, there are no further subcategories to explore under 9902.13.28. Classification within this code is definitive based on meeting all stipulated criteria: the material (viscose rayon staple fiber), the decitex value, the specific trilobal cross-section geometry, and the demonstrated suitability for manufacturing products under heading 9619. Importers must ensure their product precisely matches these detailed specifications to correctly apply this temporary provision.
