To require the Congressional Budget Office to conduct an economic review of the economic impact of tariff modifications before implementation.

This bill would change the pre-implementation process for any changes to tariffs or import duties. Specifically, it requires the Congressional Budget Office (CBO) to conduct an economic review of the expected impact of any tariff modification before it can take effect. The modification would be delayed until the CBO publishes this review on its publicly accessible website. In short, tariff changes could not enter into force until an independent, nonpartisan economic analysis is completed and publicly released. The goal appears to be introducing more evidence-based scrutiny of tariff policy, with an emphasis on transparency. However, the bill does not specify how long the review must take, what methodologies must be used, or how the analysis would be funded, which could affect the timing and feasibility of implementing tariff changes.
