HS code for Somatotropin: 2937.11
Polypeptide hormones, protein hormones and glycoprotein hormones, their derivatives and structural analogues, somatotropin, its derivatives and structural analogues.
Classification of somatotropin under HS 2937.11
Somatotropin, commonly known as growth hormone, is classified under HS code 2937.11. This classification is based on its chemical identity as a polypeptide hormone. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2937 specifically addresses hormones, their derivatives, and structural analogues. Subheading 2937.11 is reserved for somatotropin and its specific derivatives. For a product to remain in this chapter, it must be a separate chemically defined compound. This means the substance must be in its bulk form, whether produced via natural extraction or recombinant DNA technology. The classification remains consistent regardless of the biological source (human or bovine) as long as the molecular structure corresponds to somatotropin. If the somatotropin is prepared as a medicament—for example, in measured doses, in vials for clinical use, or packaged for retail sale—the classification would shift to Chapter 30. However, in its bulk, pure chemical form, 2937.11 is the correct designation. This code is vital for regulating the trade of high-value biotechnological products and ensuring they are monitored by health and agricultural authorities during transit.

Codes often confused with 2937.11
Common mistake. The most frequent misclassification is HS code 3004.31 or 3004.39. These codes are for medicaments containing hormones. If the somatotropin is already put up in vials or syringes for clinical use, it belongs in 3004. Additionally, 2937.19 is sometimes used incorrectly for other polypeptide hormones that do not have their own specific subheading, but somatotropin is explicitly named in 2937.11.
Top exporters and importers of HS 293711 (the code used for somatotropin), 2025
In 2025, the largest exporter of HS 293711 (the code used for somatotropin) in UN Comtrade data was Sweden, with 53% of world exports; the largest importer in UN Comtrade data was Belgium, with 52% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
