Importation of Defense Articles and Defense Services-U.S. Munitions Import Lists (2011R-20P) - The Department of Justice is amending Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) regulations to remove the cross reference to the regulatory United States Munitions List (USML) of the International Traffic in Arms Regulations (ITAR) that appears at 27 CFR 447.21; to clarify that the Attorney General exercises delegated authority pursuant to the Arms Export Control Act (AECA) and Executive Order 13637 to designate defense articles and defense services as part of the statutory  SML for purposes of permanent import controls, regardless of whether the Secretary of State controls such defense articles or defense services for purposes of export and temporary import; and to clarify that defense articles and defense services controlled pursuant to the Attorney General’s delegated AECA authority are part of the statutory USML (along with those that are controlled for export and temporary import by the Secretary of State), but that the list of defense articles and defense services controlled by the Attorney General is labeled the USMIL to distinguish it from the list of defense articles and defense services in the ITAR that are controlled by the Secretary of State.
