US HB7552

Amends the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 to expand sanctions authority to cover foreign government officials, employees, or agents who commit acts concerning chemical or biological programs that cause injury to other countries

Requires the President to determine within 60 days whether a foreign government individual committed a "covered act" when credible information becomes available, with mandatory sanctions upon positive determination

Establishes a three-tier sanctions structure: initial sanctions within 30 days (suspension of scientific programs, export prohibitions on Commerce Control List items, procurement bans), intermediate sanctions at 120 days (termination of foreign assistance, broader export controls, arms export license prohibitions), and final sanctions at 210 days (prohibition of financial transactions involving the country)

Defines "chemical or biological program" to include programs producing chemical/biological weapons as well as fentanyl precursors including benzylfentanyl, 4-anilinopiperidine, and norfentanyl precursors

Allows sanctions termination after 1 year if the President certifies the country has addressed the covered act, made restitution, disclosed information to international organizations, and is compliant with the Biological Weapons Convention and Chemical Weapons Convention
