Product classification
HS code for Bulk streptomycin medicaments: 3003.10
Medicaments, containing penicillins, streptomycins or their derivatives, for therapeutic or prophylactic uses, (not in measured doses, not packaged for retail sale).
Classification of bulk streptomycin medicaments under HS 3003.10
Bulk streptomycin medicaments are classified under HS code 3003.10. This classification is determined by the nature of the product as a medicament consisting of two or more constituents mixed together for therapeutic or prophylactic uses, but which has not been put up in measured doses or packaged for retail sale. Chapter 30 of the Harmonized System distinguishes between bulk mixtures (3003) and products ready for the end-user (3004). Streptomycin, an aminoglycoside antibiotic, and its derivatives are specifically called out in the first subheading of 3003. To qualify for this code, the streptomycin must be mixed with other ingredients (such as stabilizers or buffers) but remain in a bulk state, such as a large container of unmeasured powder. This classification is critical for pharmaceutical manufacturers who import active ingredients in semi-finished states for later encapsulation or tableting. The absence of retail packaging and the lack of specific dosage units (like individual vials or tablets) are the primary factors that keep the product within heading 3003 rather than 3004.

Codes often confused with 3003.10
Common mistake. The most frequent misclassification occurs with HS code 3004.10, which is for streptomycin medicaments that are already in measured doses (like pre-filled syringes) or packaged for retail sale. Additionally, pure streptomycin that has not been mixed with any other ingredients should be classified under HS code 2941.20 as a pure antibiotic, rather than a medicament of Chapter 30.

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).
