Products classified under HTS 2926.90.14.00
p-Chlorobenzonitrile
p-Chlorobenzonitrile is an aromatic nitrile-function compound featuring a benzene ring substituted with both a cyano group and a chlorine atom at the para position. It falls under HTS 2926.90.14.00 as a specifically named aromatic nitrile used primarily as an intermediate in pharmaceutical and agrochemical synthesis. This chemical is a separate, chemically defined organic compound consistent with Chapter 29 note (a).
Verapamil Hydrochloride
Verapamil hydrochloride is the hydrochloride salt of verapamil, a calcium channel blocker used primarily for hypertension and angina treatment. As an aromatic nitrile-function compound (specifically named), it classifies under HTS 2926.90.14.00 per Chapter 29 note on salts of organic compounds. The nitrile group and aromatic structure define its placement among pharmaceutical nitriles.
Verapamil HCl USP Grade
USP-grade Verapamil Hydrochloride meets United States Pharmacopeia standards for pharmaceutical use, containing the specified aromatic nitrile-function compound as hydrochloride salt. Classified specifically under HTS 2926.90.14.00 among named nitriles rather than general pharmaceuticals. Purity ≥99.0% with verified polymorphic form ensures tariff accuracy.
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.
