Ergotamine tartrate is the principal commercial form of this vasoconstrictor alkaloid, used in migraine treatment and as a precursor in the synthesis of other ergot-derived pharmaceuticals. The Czech Republic is the primary US supplier, reflecting the concentration of ergot alkaloid manufacturing capacity in Central Europe. Imports enter under tariff line 2939620000 and are subject to both FDA drug admissibility requirements and DEA List I chemical controls, given ergotamine's role as a regulated precursor. Supply chain risk is elevated by the narrow supplier base, making sourcing continuity a key concern for pharmaceutical manufacturers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Central European countries, particularly the Czech Republic, have long-established fermentation and extraction infrastructure for ergot alkaloid production. This specialized manufacturing base, combined with regulatory compliance with both EU and US standards, has made the region the primary source for ergotamine and related compounds.
Ergotamine is a DEA List I chemical. Importers must be registered with the DEA, obtain an import permit for each shipment, and comply with recordkeeping and reporting requirements under the Controlled Substances Act. These requirements apply regardless of whether the intended use is pharmaceutical or research.
