HS Code for Diazepam

Diazepam is classified under HS code 2933.91 as a heterocyclic compound with nitrogen hetero-atom(s) only. Chapter 29 of the Harmonized System covers organic chemicals. Within this chapter, heading 2933 is dedicated to heterocyclic compounds containing nitrogen. Subheading 2933.91 specifically names several benzodiazepine derivatives, including diazepam (INN). The classification at this level is reserved for the pure chemical substance or the substance in a bulk, non-dosage form. The International Nonproprietary Name (INN) \"diazepam\" is explicitly listed in the tariff nomenclature, making the classification straightforward for the raw chemical. This classification applies to the active pharmaceutical ingredient (API) before it has been formulated into a finished medicament. It is essential for importers to distinguish between the bulk chemical used in manufacturing and the finished pharmaceutical product, as the regulatory and duty requirements differ significantly between the two categories.

Products Included

• Pure diazepam powder (bulk)
• Diazepam (INN) for pharmaceutical synthesis
• Camazepam, chlordiazepoxide, and clonazepam (same subheading)
• Bulk benzodiazepine derivatives listed in 2933.91

Common Misclassification

The most frequent misclassification occurs when diazepam is imported in tablet, capsule, or injectable form. In these cases, it should be classified under HS code 3004.90 as a medicament put up in measured doses for retail sale. Another error is using the general heterocyclic code 2933.99, which is incorrect because diazepam is specifically named in the 2933.91 subheading.
