HS Code 2937.50 – Prostaglandins, thromboxanes and leukotrienes, their derivatives and structural analogues
HS code 2937.50 is the 6-digit subheading for prostaglandins, thromboxanes and leukotrienes, their derivatives and structural analogues. It is used for misoprostol, latanoprost, dinoprostone, alprostadil and montelukast.
What HS 2937.50 covers
This HS code covers prostaglandins, thromboxanes, and leukotrienes, along with their derivatives and structural analogues. These are lipid compounds with potent hormone-like effects, playing critical roles in various physiological processes such as inflammation, blood clotting, and smooth muscle contraction. They are widely used in pharmaceuticals for applications ranging from inducing labor and treating glaucoma to managing asthma and gastric ulcers. International trade is primarily conducted by pharmaceutical companies and specialized biotech firms, which produce and export these high-value active ingredients. Key aspects of this trade include complex synthesis processes, stringent quality control, and adherence to global pharmaceutical regulations. Their potent biological activity necessitates careful handling and precise formulation for therapeutic use.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
