2926.90.16.00 - [1α(S*),3α(Z)]-(±)-Cyano(3-phenoxyphenyl)- methyl 3-(2-chloro-3,3,3-trifluoro-1-propenyl)- 2,2-dimethylcyclopropanecarboxylate

This HTS category, HTS Code 2926.90.16.00, specifically covers a complex organic compound characterized by its chemical structure. The description "[1α(S*),3α(Z)]-(±)-Cyano(3-phenoxyphenyl)- methyl 3-(2-chloro-3,3,3-trifluoro-1-propenyl)- 2,2-dimethylcyclopropanecarboxylate" indicates a nitrile-function compound with a specific stereochemical configuration and a multi-ringed aromatic and alicyclic structure. This compound is a synthetic chemical, likely used as an intermediate or active ingredient in specialized industrial applications.

Distinguishing this category from its siblings, such as various benzonitriles or amino-chlorobenzonitriles, is crucial. While all fall under "Nitrile-function compounds: Other: Aromatic," this entry represents a significantly more complex and specifically defined molecule. The presence of a phenoxyphenyl group, a trifluoro-propenyl substituent, and a cyclopropanecarboxylate ester moiety differentiates it from simpler aromatic nitriles and those with different functional group combinations. The precise stereochemical designation further narrows its scope.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification within this code relies entirely on the exact chemical identity and structural features of the imported or exported product matching the detailed description provided. Customs professionals should verify that the goods possess all specified chemical groups and stereoisomeric characteristics to ensure accurate classification under 2926.90.16.00, rather than any broader or more general nitrile category.
