HS Code for Loprazolam

Loprazolam is classified under HS code 2933.55 as a specific heterocyclic compound. Chapter 29 of the Harmonized System deals with organic chemicals. Heading 2933 covers heterocyclic compounds with nitrogen hetero-atom(s) only. Within this heading, the chemical structure of the molecule determines the subheading. Loprazolam contains a pyrimidine ring (which may be hydrogenated) or a piperazine ring in its structure. Subheading 2933.55 is a specific provision for several International Nonproprietary Name (INN) substances, including loprazolam, mecloqualone, methaqualone, and zipeprol, as well as their salts. Classification here is strictly based on the chemical structure and the specific naming of the substance in the HS nomenclature. This follows General Interpretative Rule 1, as the subheading text explicitly names the substance. It is important to note that this code applies to the pure chemical substance or its salts. If the substance is prepared as a medicament in measured doses or in forms for retail sale, the classification would shift to Chapter 30. However, as a bulk raw chemical, 2933.55 is the mandatory classification for Loprazolam.

Common Misclassification

Loprazolam is often misclassified under 3004.90 if it is in the form of finished tablets, as Chapter 30 takes precedence for medicaments. Another error is using 2933.91, which covers other benzodiazepines like diazepam, chlordiazepoxide, or oxazepam. While Loprazolam is a benzodiazepine derivative, the presence of the pyrimidine/piperazine ring structure and its explicit mention in 2933.55 requires it to be classified there instead of the general benzodiazepine subheading.
