4-Chlorobenzonitrile Technical Grade from Canada
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.

Import Tips
• 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
