9902.04.80 - 2, 2-Diphenylacetonitrile (CAS No. 86-29-3) (provided for in subheading 2926.90.48)

This HTS category, 9902.04.80, specifically covers 2,2-Diphenylacetonitrile, identified by CAS Number 86-29-3. While the primary classification of this chemical falls under subheading 2926.90.48 within the Harmonized System, its inclusion in Chapter 99 indicates it is subject to temporary legislation or special import provisions. These provisions are enacted under broader trade agreements or specific agricultural adjustments and may involve quotas, duties, or other restrictions beyond its standard tariff classification.

As a specific item under temporary provisions, this category does not have direct siblings in the traditional sense of comparable goods at the same hierarchical level. Its uniqueness stems from its placement within Chapter 99, which is reserved for special classifications rather than broad product groupings. Unlike the vast array of product categories found in Chapters 01 through 98, Chapter 99 entries are distinct and often apply to single or narrowly defined items due to specific policy directives.

Since this node is a leaf node, there are no further subcategories within 9902.04.80. Classification within this entry is definitive, and any goods meeting the description of 2,2-Diphenylacetonitrile are to be classified here when applicable under the stated temporary legislation. This highlights the specialized nature of Chapter 99, which often serves as an overlay to the standard HTS structure to manage specific trade situations.
