Heterocyclic compounds, alprazolam (INN), camazepam (INN), chlordiazepoxide (INN), clonazepam (INN), clorazepate, delorazepam (INN), diazepam (INN), estazolam (INN), ethyl loflazepate (INN), fludiazepam (INN), flunitrazepam (INN), (cont).

Classification of alprazolam under HS 2933.91

Alprazolam is classified under HS code 2933.91 due to its chemical structure and specific identification as a heterocyclic compound. Chapter 29 of the Harmonized System covers "Organic chemicals." Within this chapter, heading 2933 is dedicated to "Heterocyclic compounds with nitrogen hetero-atom(s) only." Alprazolam, being a benzodiazepine, falls under this category. The subheading 2933.91 specifically lists "Alprazolam (INN), camazepam (INN), chlordiazepoxide (INN), clonazepam (INN), clorazepate, delorazepam (INN), diazepam (INN), estazolam (INN), ethyl loflazepate (INN), fludiazepam (INN), flunitrazepam (INN)" and other similar compounds. The "INN" (International Nonproprietary Name) designation further confirms its specific chemical identity and classification within this precise subheading, ensuring accurate customs control and regulatory compliance for pharmaceutical substances.

Codes often confused with 2933.91

Common mistake. Common misclassification for alprazolam might occur with other subheadings within 2933 if the specific INN is not recognized, or with broader categories like 2933.99, which covers "Other" heterocyclic compounds with nitrogen hetero-atoms only, not elsewhere specified. However, since alprazolam is explicitly named in 2933.91, this is the most accurate classification. Confusion could also arise with finished pharmaceutical products (medicaments) containing alprazolam, which are typically classified under Chapter 30, specifically heading 3004 (Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale). HS code 2933.91 is strictly for the bulk chemical substance, not the retail-ready drug.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
