2926.90.17.00 - o-Chlorobenzonitrile

This HTS classification covers o-Chlorobenzonitrile, a specific aromatic nitrile. Aromatic nitriles are characterized by a cyano group (-CN) directly attached to an aromatic ring. Within the broader category of "Other" nitrile-function compounds, this subcategory focuses on those where the nitrile group is bonded to an aromatic system.

Distinguishing o-Chlorobenzonitrile from its sibling categories is crucial for accurate classification. For instance, while other siblings like 2-Cyano-4-nitroaniline or various Dichlorobenzonitriles also contain aromatic nitrile structures, they differ by the specific substituents on the aromatic ring and their positions. The presence of a single chlorine atom at the *ortho* position relative to the nitrile group is the defining characteristic of this entry. Entries like p-Chlorobenzonitrile or Benzonitrile itself represent different positional isomers or the unsubstituted parent compound, respectively.

As a leaf node within the HTS, 2926.90.17.00 represents a specific chemical entity with no further subdivisions. Classification under this code is determined by the precise chemical identity of the imported or exported substance. Importers and exporters must ensure that the product's chemical composition precisely matches that of o-Chlorobenzonitrile to warrant classification under this HTS code.
