Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed with excipients for tablet compression
Medicaments in bulk (unmeasured doses) with this API shift to Chapter 30 if containing excipients exceeding 10% w/w.
If amine function declared primary over nitrile
Compounds with multiple nitrogen functions classify to latest heading; verapamil's amine may supersede nitrile under numerical order rule.

Import Tips & Compliance
• USP certificate mandatory; include HPLC chromatogram showing single peak at 99%+ area for CBP verification
• Type II DMF filing required before first import; avoid 'research use only' labeling which triggers different regulatory path
• Particle size distribution data prevents reclassification as micronized finished intermediate under Chapter 30

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.
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.
