Last updated: April 2026 dataEphedrine-related alkaloids not covered by the named headings for ephedrine, pseudoephedrine, cathine, norephedrine, or metamfetamine fall here, with the US schedule capturing remaining ephedrines and their salts at 2939490300. These compounds retain List I chemical status under the Controlled Substances Act, requiring DEA import permits and quota compliance regardless of their specific structural variant. Taiwan and Canada are the recorded suppliers under this residual heading, suggesting niche pharmaceutical or research-grade sourcing rather than large-volume API trade. The NESOI character of this heading means precise chemical identification in import documentation is critical to avoid misclassification into a named-substance line.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The importer must provide a certificate of analysis confirming the specific INN name or chemical identity of the alkaloid. If the substance is ephedrine, pseudoephedrine, cathine, norephedrine, or metamfetamine, it must be classified under its respective named tariff line rather than the NESOI line 2939490300. Only alkaloids of ephedra that do not match any of those named substances belong here. CBP may request additional structural documentation or a binding ruling if the identity is ambiguous.
Yes. The NESOI heading captures ephedra alkaloids and their derivatives that are structurally related to the named List I chemicals. DEA treats these compounds as List I chemicals subject to importer registration, per-shipment import permits, and annual quota controls. Importers should confirm with DEA whether a specific novel ephedra derivative requires a scheduling determination before attempting importation, as some derivatives may be subject to analogue provisions.
