Ephedrine-based medicaments in measured doses fall under strict dual-track oversight: FDA regulates them as finished pharmaceutical products, while the DEA imposes additional controls because ephedrine is a listed chemical precursor under the Combat Methamphetamine Epidemic Act. The single US tariff line for this heading is 3004410000, covering both mixed and unmixed formulations containing ephedrine alkaloids or their salts. Importers must ensure the foreign manufacturer holds FDA drug establishment registration and that shipments comply with DEA import quota requirements before goods can be released at the port of entry. Classification hinges on whether the active alkaloid is ephedrine specifically, as pseudoephedrine and norephedrine are carved out into separate HS6 headings.
