HS code for Levorphanol: 2933.41
Heterocyclic compounds, containing a quinoline or isoquinoline ring-system (whether or not hydrogenated) in the structure, not further fused, levorphanol (INN) and its salts.
Classification of levorphanol under HS 2933.41
Levorphanol and its salts are classified under HS code 2933.41. This code is found in Chapter 29, which covers organic chemicals. Heading 2933 is dedicated to heterocyclic compounds with nitrogen hetero-atom(s) only. Specifically, subheading 2933.41 covers compounds containing a quinoline or isoquinoline ring-system (whether or not hydrogenated) in the structure, not further fused. Levorphanol is an opioid medication and is specifically listed by its International Nonproprietary Name (INN) in the HS nomenclature. The classification is determined by the chemical structure of the molecule, which features a morphinan core that includes a quinoline ring system. As a controlled substance, the precise classification of Levorphanol is critical for international monitoring by narcotics control boards. Under GRI 1, the specific mention of 'Levorphanol (INN) and its salts' in the subheading text takes precedence over more general categories. This code applies to the chemical in its pure form or as a salt (such as levorphanol tartrate), provided it is not yet formulated into a finished medicament.

Codes often confused with 2933.41
Common mistake. Levorphanol is frequently misclassified under 2933.49, which is the 'other' category for quinoline ring systems. However, because it is an INN-named substance, 2933.41 must be used. It is also often confused with 3004.90, which covers medicaments in measured doses. If the Levorphanol is already in pill or injectable form for retail sale, it moves from Chapter 29 to Chapter 30.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
