DEA Finalizes New Import, Export Restrictions for Fentanyl Precursor Chemical

The Drug Enforcement Administration is finalizing controls on 4-piperidone as a list I chemical under the Controlled Substances Act. The chemical is used in the manufacture of fentanyl, DEA said. The agency is not setting a threshold for domestic and international transactions for these chemicals, so “all transactions involving 4-piperidone, regardless of size, shall be regulated and are subject to control under the CSA," and "chemical mixtures containing 4-piperidone are not exempt from regulatory requirements at any concentration." The listing takes effect May 12.
