Fenproporex is a Schedule IV controlled stimulant under the Controlled Substances Act, and the methadone intermediate covered by this heading is a precursor to a Schedule II opioid — meaning DEA import authorization and strict quota compliance are mandatory for any commercial shipment. Both substances are covered by a single 10-digit line, 2926300000. India is the sole recorded US import supplier under this heading, reflecting the limited number of licensed manufacturers globally. Misclassification of these compounds as ordinary nitrile-function chemicals carries serious legal consequences.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Importers must hold a DEA Schedule I/II or Schedule IV import registration as applicable, obtain import permits for each shipment, and comply with annual aggregate production quota allocations. Both substances are also subject to international control under the UN Convention on Psychotropic Substances or the Single Convention on Narcotic Drugs.
The US HTS consolidates them under 2926300000 because both are nitrile-function compounds with controlled-substance status and limited commercial trade volume, making separate statistical tracking impractical. Importers must still identify the specific substance on entry documentation to satisfy DEA permit requirements.
