Cathine — also known as norpseudoephedrine — is a naturally occurring phenethylamine alkaloid found in khat (Catha edulis) and is classified as a Schedule IV controlled substance in the US, requiring DEA importer registration and import authorization for shipments under 2939430000. Its pharmaceutical applications are limited primarily to appetite suppression in certain European markets, and Germany is the sole recorded US supplier under this heading. The narrow supplier base and Schedule IV status mean that any supply disruption or DEA quota adjustment can significantly affect availability for the small number of licensed US importers.

Cathine (norpseudoephedrine) is one of the active alkaloids naturally present in khat plant material. However, isolated cathine and its salts classify under 2939430000 as a pure chemical, while khat plant material would be subject to entirely different classification and DEA Schedule I controls as a plant containing cathinone. Importers of isolated cathine must ensure their documentation clearly establishes that the product is the purified chemical compound, not plant-derived material.
Cathine has limited approved pharmaceutical use in the US. It appears in some European appetite-suppressant formulations, and US imports are primarily destined for research or pharmaceutical development purposes. Any importer must hold a DEA Schedule IV registration and demonstrate a legitimate pharmaceutical or research end-use to obtain import authorization.
