## Abstract

The Drug Enforcement Administration is correcting a final order that appeared in the Federal Register on November 29, 2018. The document issued an action maintaining the placement of furanyl fentanyl, 4-fluoroisobutyryl fentanyl, acryl fentanyl, tetrahydrofuranyl fentanyl, and ocfentanil, including their isomers, esters, ethers, salts, and salts of isomers, esters and ethers, in schedule I of the Controlled Substances Act. A drafting oversight in the amendatory instructions did not correctly update the prefatory language on isomers to reflect the change in the paragraph number for the designation of 3-methylthiofentanyl.
