Imposing Measures on Sudan for its Use of Chemical Weapons

On April 24, 2025, the United States determined under the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (the CBW Act) that the Government of Sudan used chemical weapons in 2024. 

This determination was delivered to Congress today, along with an addendum to the April 15, 2025, Condition 10(C) Report on Compliance with the Chemical Weapons Convention (CWC) that finds the Government of Sudan in non-compliance with the CWC, to which it is a party.  Following a 15-day Congressional notification period, the United States will impose sanctions on Sudan, including restrictions on U.S. exports to Sudan and on access to U.S. government lines of credit. 

The sanctions will take effect upon publication of a notice in the Federal Register, expected on or around June 6, 2025. 

The United States calls on the Government of Sudan to cease all chemical weapons use and uphold its obligations under the CWC. 

The United States remains fully committed to hold to account those responsible for contributing to chemical weapons proliferation.
