ATF periodically publishes Open Letters to the industries it regulates in order to remind or assist licensees with understanding their regulatory compliance responsibilities under the laws and regulations administered by ATF. Open Letters do not have the force and effect of federal statutes or Department of Justice regulations, and are not final agency actions. They may also be rescinded or modified at ATF’s discretion.
For more information, see “Memorandum for All Components: Prohibition of Improper Guidance Documents,” from Attorney General Jefferson B. Sessions III, November 16, 2017.
