4-Chlorobenzonitrile Technical Grade
Technical grade 4-chlorobenzonitrile (synonym for p-chlorobenzonitrile) contains ≥98% active ingredient with minor impurities, used as a synthetic intermediate for herbicides like chlorimuron-ethyl. It remains classified under HTS 2926.90.14.00 as the specifically named aromatic nitrile per Chapter 29 note (a) allowing impurities. The para-chloro substitution on the benzonitrile core defines its precise tariff placement.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-formulated into herbicide intermediate mixture
Pesticide formulations containing this nitrile as active ingredient classify under Chapter 38, not pure compounds of Chapter 29.
If for industrial quantities lacking pharma-grade purity
Lower purity industrial chlorobenzonitriles may classify as halogenated aromatic hydrocarbons if nitrile function secondary.

Import Tips & Compliance
• Technical grade requires spec sheet showing <2% impurities; higher impurity levels risk reclassification as 3824 chemical mixture
• EPA pesticide chemical code required if end-use is herbicide intermediate; TSCA notification for new chemical processes
