HS Code for Clobazam

Clobazam is classified under HS code 2933.72. This classification falls within Chapter 29, which covers organic chemicals, and specifically heading 2933, which encompasses heterocyclic compounds with nitrogen hetero-atom(s) only. Clobazam is a 1,5-benzodiazepine, but for the purposes of the Harmonized System, it is categorized under the subheading for lactams. A lactam is a cyclic amide, and the structure of clobazam includes this functional group within its seven-membered ring. The classification 2933.72 is a specific 'named' subheading that also includes methyprylon. This level of specificity is used because clobazam is a psychotropic substance subject to international control under the 1971 Convention on Psychotropic Substances. Accurate classification is vital for regulatory monitoring by the International Narcotics Control Board (INCB). This code applies to the pure chemical substance (the raw material) or its salts. If the clobazam has been formulated into a finished dosage form, such as a tablet for retail sale, the classification would change to Chapter 30.

Common Misclassification

Clobazam is frequently misclassified under HS code 2933.91, which covers other benzodiazepines like diazepam, lorazepam, and alprazolam. While clobazam is a benzodiazepine, the HS nomenclature provides a specific subheading (2933.72) for it because of its lactam structure, which takes precedence over the general benzodiazepine subheading. Another common error is classifying it under 3004.90. This occurs when the importer confuses the bulk chemical with the finished medicament. HS code 3004 is only for products put up in measured doses or for retail sale.
