Exemption of chemical mixtures containing the List I chemicals ephedrine,N-methylephedrine,N-methylpseudoephedrine,norpseudoephedrine, phenylpropanolamine,and pseudoephedrine. Final rule

On September 16, 1998, the Drug Enforcement Administration (DEA) published a Notice of Proposed Rulemaking (NPRM) to implement provisions of the Controlled Substances Act (CSA) pertaining to the regulation of chemical mixtures which contain any of 34 listed chemicals. The NPRM was published to implement CSA requirements that only those chemical mixtures identified by regulation be exempt from applicable regulatory controls. The NPRM proposed criteria for the determination of whether a chemical mixture shall qualify for automatic exemption from CSA regulatory controls. Additionally, the NPRM defined an application process by which manufacturers may apply for an exemption for chemical mixtures that do not qualify for automatic exemption. Due to concerns regarding the potential illicit use of chemical mixtures which contain ephedrine, N-methylephedrine, N- methylpseudoephedrine, norpseudoephedrine, phenylpropanolamine, and/or pseudoephedrine (as precursor material for the production of methamphetamine and related amphetamines), DEA is hereby finalizing the portion of the NPRM pertaining to these six chemicals. Final regulations for all remaining listed chemicals will be published under separate rulemaking, upon completion of a thorough review of applicable comments.
