HS code for Progesterone: 2937.23

Steroidal hormones, their derivatives and structural analogues, oestrogens and progestogens.

Classification of progesterone under HS 2937.23

Progesterone is a steroidal hormone classified under HS code 2937.23. This code falls within Chapter 29, which covers organic chemicals. Heading 2937 specifically addresses hormones, their derivatives, and structural analogues used primarily as active pharmaceutical ingredients (APIs). Subheading 2937.23 is dedicated to oestrogens and progestogens. The classification is based on the chemical structure and biological function of the substance as a hormone. Progesterone is a naturally occurring steroid involved in the human reproductive system, but for international trade, it is often handled as a pure synthetic compound. As long as the substance is a separate chemically defined compound and has not been mixed with other ingredients for therapeutic use, it remains in Chapter 29. This classification is vital for regulatory compliance regarding controlled substances and pharmaceutical precursors.

Codes often confused with 2937.23

Common mistake. Progesterone is frequently misclassified under 3004 if it is already formulated into a medicine (e.g., tablets or injections for retail sale). It may also be confused with other steroids like cortisone or prednisone, which are classified under 2937.21. Accurate chemical identification is required to distinguish between different steroidal subheadings.

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).
