Unlike a standard pharmaceutical API, norephedrine requires a DEA chemical importer registration (separate from a drug importer registration), a DEA import permit for each individual shipment, and compliance with annual aggregate import quotas. Importers must also file DEA transaction reports and maintain records for two years. These requirements apply in addition to any FDA drug facility registration obligations if the material is destined for pharmaceutical manufacturing.

With India as the sole recorded supplier, importers face concentration risk from regulatory, logistical, or geopolitical disruptions affecting Indian API exports. DEA quota constraints compound this risk — if an importer's annual quota is insufficient to cover a supply gap, there is no straightforward mechanism to source from an alternative country mid-year. Importers should factor quota lead times and safety stock requirements into their procurement planning.
