CBW Fentanyl Act

S 63, the "CBW Fentanyl Act," amends U.S. law to impose sanctions on foreign countries associated with officials who commit "covered acts" related to chemical or biological programs. It targets actions involving specific substances like benzylfentanyl (a fentanyl analog) and precursors, requiring the President to report on such acts and impose tiered sanctions - including suspending scientific cooperation, banning exports of controlled items, and restricting procurement from chemical/biological sectors - within 30-210 days. Sanctions escalate if countries fail to address violations, provide information, or comply with treaties like the Chemical Weapons Convention. The bill directly affects foreign governments and entities linked to these programs, with sanctions terminating after 1 year if compliance is achieved. (Note: Despite the title referencing fentanyl, the bill focuses on broader chemical/biological program violations under existing international treaties.)
