CBO Economic Review Requirement for Tariff Modifications (HR4326)

Current understanding

HR4326 (introduced) would prohibit any tariff or duty modification from taking effect until the Congressional Budget Office publishes an economic impact review on a publicly available website. The measure is a procedural constraint layered on top of existing tariff authorities (e.g., Section 232, Section 301, IEEPA-based actions) rather than a substantive change to trade policy. Status: introduced; no committee action or scoring described.
