HS code for Lysergic acid: 2939.63
Alkaloids, of rye ergot and their derivatives, lysergic acid and its salts.
Classification of lysergic acid under HS 2939.63
Lysergic acid is classified under HS code 2939.63 as an alkaloid of rye ergot. The Harmonized System organizes organic chemicals in Chapter 29 based on their molecular structure and functional groups. Heading 2939 is dedicated to vegetable alkaloids, which are nitrogenous organic compounds of plant origin. Lysergic acid is a specific derivative of the ergot alkaloids found in the fungus Claviceps purpurea. The classification 2939.63 is precise for the acid itself and its various salts. This classification is maintained regardless of the intended use, whether for pharmaceutical research or as a precursor in chemical synthesis, provided the substance remains a separate chemically defined compound as required by the Note 1 to Chapter 29.

Codes often confused with 2939.63
Common mistake. Lysergic acid is often confused with other ergot alkaloids such as Ergometrine (2939.61) or Ergotamine (2939.62). While these substances share a similar chemical backbone, the HS nomenclature provides specific subheadings for each major ergot derivative. Misclassifying lysergic acid under the 'other' category of 2939.69 is also a common error; however, because lysergic acid is explicitly named in the 2939.63 subheading, the specific code must take precedence over the general one according to GIR 3(a). Additionally, it should not be confused with synthetic drugs in heading 2933.
Top exporters and importers of HS 293963 (the code used for lysergic acid), 2025
In 2025, the largest exporter of HS 293963 (the code used for lysergic acid) in UN Comtrade data was Hungary, with 86% of world exports; the largest importer in UN Comtrade data was Czechia, with 77% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 293963, not only lysergic acid.

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).
