Product classification
HS code for Streptomycin: 2941.20
Antibiotics, streptomycins and their derivatives, salts thereof.
Classification of streptomycin under HS 2941.20
Streptomycin and its derivatives are classified under HS code 2941.20. Chapter 29 covers organic chemicals, and heading 2941 is dedicated to antibiotics. Subheading 2941.20 specifically identifies streptomycins, their derivatives, and their salts. This classification is used for the bulk chemical substance rather than finished dosage forms prepared for therapeutic use. The chemical structure of streptomycin, an aminoglycoside antibiotic derived from Streptomyces griseus, defines its placement here. Derivatives such as dihydrostreptomycin are also included, provided they retain the core chemical characteristics of the parent compound. This code is vital for the pharmaceutical industry and regulatory bodies to track the movement of raw antibiotic materials. It ensures that the substance is treated as a chemical intermediate or raw material rather than a finished medicament, which would be subject to different pharmaceutical regulations and trade controls.

Codes often confused with 2941.20
Common mistake. Streptomycin is frequently misclassified under HS code 3004.10. However, Chapter 30 is for medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or for retail sale. If the streptomycin is in bulk form, it must stay in 2941.20. It is also sometimes confused with 2941.10, which is specifically for penicillins.
Top exporters and importers of HS 294120 (the code used for streptomycin), 2025
In 2025, the largest exporter of HS 294120 (the code used for streptomycin) in UN Comtrade data was China, with 73% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 13% 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).
