What HS 2939.43 covers

These compounds are naturally occurring or synthetic substances with stimulant properties, often used in pharmaceuticals as decongestants, bronchodilators, or appetite suppressants. Due to their stimulant effects and potential for misuse or diversion into illicit drug manufacturing, international trade in these substances is highly regulated under international drug control conventions. Only licensed pharmaceutical manufacturers, distributors, and research institutions are authorized to import or export these compounds, requiring strict adherence to national and international drug control laws, detailed record-keeping, and secure handling. Purity and pharmaceutical grade are essential.

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).
