HS Code 29.39 – Alkaloids; natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives

HS code 2939 is a 4-digit heading in the Harmonized System that covers: Alkaloids; natural or reproduced by synthesis, and their salts, ethers, esters and other derivatives. HS Code 2939 covers alkaloids, both natural and reproduced by synthesis, and their salts, ethers, esters, and other derivatives. Alkaloids are a diverse group of naturally occurring organic compounds containing nitrogen, predominantly found in plants, which exhibit pronounced physiological effects on humans and animals. This heading is profoundly important for the pharmaceutical industry, as it includes powerful medicinal compounds such as morphine, quinine, and caffeine, used for pain relief, antimalarial treatment, and stimulation, respectively. The scope encompasses the isolated, chemically pure forms of these compounds and their direct chemical modifications, rather than crude plant materials or finished drug products. Classification under 2939 is critical for trade compliance due to the often-potent and sometimes controlled nature of these substances. Many alkaloids are narcotic drugs or psychotropic substances, subject to stringent international conventions and national regulations, requiring special licenses, permits, and secure transport. Historically, alkaloids have been at the forefront of medicinal chemistry, providing foundational drugs. This heading is part of Chapter 29, emphasizing their identity as specific, complex nitrogenous organic chemicals, distinct from the plants they are derived from or the final drug formulations.

Morphine, Codeine, Caffeine, Nicotine, Quinine, Strychnine, Atropine, Cocaine, Ephedrine, Pseudoephedrine, Theophylline, Ergotamine, Reserpine, Vincristine, Vinblastine, Pilocarpine, Scopolamine, Berberine, Colchicine, Papaverine, Hydromorphone, Oxycodone, Fentanyl (base form), Pethidine, Ecgonine

A common misclassification involves confusing pure alkaloids (2939) with crude plant extracts (Chapter 13) or finished pharmaceutical products (Chapter 30). If the product is a raw plant extract containing alkaloids but not isolated to a chemically pure form, it may fall under 1302. If alkaloids are formulated into measured doses (e.g., morphine tablets, caffeine pills) for therapeutic or prophylactic use, they classify under Chapter 30 (e.g., 3004). Another error is misclassifying other nitrogen-containing organic compounds that are not alkaloids (e.g., amino acids, amides) here; these belong to other specific headings within Chapter 29 (e.g., 2922-2929). The key is the distinct chemical structure and physiological activity characteristic of alkaloids.

In 2025, the top exporters of HS code 2939 in UN Comtrade data were Germany ($405M, 17% of world exports), India ($366M) and China ($275M). World exports came to about $2.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 2939 in UN Comtrade data were the United States ($606M, 22% of world imports), Germany ($258M) and Italy ($173M). World imports came to about $2.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 2939 is a 4-digit heading under Chapter 29 of the Harmonized System. The first 2 digits (29) identify the chapter, and digits 3-4 (39) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
