The Americas Regional Monitoring of Arms Sales Act of 2025 aims to enhance the oversight of munitions exports by transferring regulatory authority from the Department of Commerce to the Department of State. This shift is intended to improve control over the export of firearms and munitions, particularly in response to rising concerns about gun violence and trafficking in Mexico, Central America, and the Caribbean. Key provisions of the legislation require the Secretary of Commerce to transfer control of specific munitions exports to the Secretary of State within one year of enactment.
