2926.90.14.00 - p-Chlorobenzonitrile; and Verapamil hydrochloride

This HTS classification covers specific nitrile-function compounds, particularly aromatic ones that do not fall into more specific subheadings. Notably, it includes p-Chlorobenzonitrile, a chemical used as an intermediate in the synthesis of various organic compounds, and Verapamil hydrochloride, a pharmaceutical agent used to treat cardiovascular conditions such as hypertension and arrhythmias. The inclusion of both a simple aromatic nitrile and a complex pharmaceutical highlights the diverse nature of the "other" aromatic nitrile category.

Distinguishing this subheading from its siblings requires careful attention to the specific chemical structures and known uses of the enumerated substances. For example, sibling categories may cover specific dichlorobenzonitriles, or other uniquely defined aromatic nitriles like 2-Cyano-4-nitroaniline or Benzonitrile itself. This classification serves as a residual category for aromatic nitrile-function compounds not otherwise specified.

As this classification node is a leaf node, it has no further subdivisions. The classification of p-Chlorobenzonitrile and Verapamil hydrochloride at this specific code signifies that these particular substances have been definitively assigned to this category based on their chemical identity and function, and do not require further breakdown within the HTS for import or export purposes.
