DEA Proposes New Import, Export Restrictions for Fentanyl Precursor Chemical

The Drug Enforcement Administration is proposing to control 4-piperidone as a list I chemical under the Controlled Substances Act. The chemical is used in the manufacture of fentanyl, DEA said. DEA is not proposing a threshold for domestic and international transactions for these chemicals, so “all transactions of chemical mixtures containing 4-piperidone will be regulated at any concentration and will be subject to control under the Controlled Substances Act,” the agency said. Comments are due Oct. 24.
