Classification of bromazepam under HS 2933.33

Bromazepam is classified under HS code 2933.33. This is a highly specific classification within the organic chemicals chapter (Chapter 29). The code 2933 covers heterocyclic compounds with nitrogen hetero-atom(s) only, specifically those containing an unfused pyridine ring in the structure. Bromazepam is explicitly listed in the nomenclature for 2933.33 because it is a controlled substance under international conventions, specifically the 1971 Convention on Psychotropic Substances. This explicit naming ensures that customs authorities can monitor the trade of this benzodiazepine derivative accurately for both regulatory and statistical purposes. The classification remains in 2933.33 as long as the product is a separate chemically defined compound, regardless of its purity, provided it has not been mixed with other ingredients to form a medicament. This code is essential for ensuring that the substance is handled according to international drug control laws and that the necessary import permits from health authorities are present during the customs clearance process.

Codes often confused with 2933.33

Common mistake. A frequent error is classifying Bromazepam under HS code 3004.90. While 3004.90 covers medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses (like tablets) or in forms for retail sale, HS code 2933.33 is reserved for the raw chemical compound itself. If the Bromazepam is imported as a bulk powder for pharmaceutical manufacturing, it must stay in 2933.33. Another potential error is using 2933.39, which is the "other" category for pyridine derivatives; however, since Bromazepam is specifically named in the 2933.33 subheading, the specific code takes precedence over the general one according to GRI 3(a).

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).
