The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic opioid, N-(1-phenethylpiperidin-4-yl)-N-phenylacrylamide (acryl fentanyl or acryloylfentanyl), and its isomers, esters, ethers, salts and salts of isomers, esters, and ethers, into Schedule I. This action is based on a finding by the Administrator that the placement of acryl fentanyl into Schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to Schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, acryl fentanyl.
