9902.13.10 - Acrylic staple fibers containing at least 85 percent by weight of acrylonitrile units and 2 percent or more but not over 3 percent of water, raw white (undyed), crimped, with an average decitex of 1.3 (plus or minus 10 percent) and fiber length of 38 mm (plus or minus 10 percent) (provided for in subheading 5503.30.00)

This HTS category, 9902.13.10, designates specific acrylic staple fibers subject to temporary classification provisions. These fibers are characterized by a high acrylonitrile content (at least 85% by weight) and a controlled moisture level (2% to 3%). Additional defining attributes include being raw white (undyed), crimped, and possessing precise average decitex (1.3 +/- 10%) and fiber length (38 mm +/- 10%) specifications. This detailed description ensures precise identification and application of the temporary legislation or import restrictions associated with this classification.

As a temporary provision under Chapter 99, this category serves a distinct purpose beyond the standard classification of acrylic fibers found in Chapter 55. While its base material and physical properties align with those described in subheading 5503.30.00, its presence in Chapter 99 signifies that it is subject to specific, time-limited trade policies. Unlike the permanent classifications in earlier chapters, such as live animals (Chapters 01), which are categorized by species and intended use, 9902.13.10 addresses a specific type of textile raw material under a unique regulatory framework.

This particular HTS code is a leaf node, meaning it has no further subdivisions. Its specificity reflects a targeted approach to managing the import of these particular acrylic staple fibers, likely due to economic or trade agreement considerations. Classification into this node hinges entirely on meeting all the enumerated technical specifications outlined in the description, differentiating it from any other acrylic fiber classification, whether under permanent or other temporary provisions.
