Tariff Transparency Act of 2025

Introduced March 11, 2025

AI-Generated Summary

Updated November 24, 2025 at 2:00 AM UTC

The Tariff Transparency Act of 2025 directs the U.S. International Trade Commission to study how proposed high tariffs on imports from Mexico and Canada, as well as the risk of future duties, would affect U.S. consumer prices and businesses. It requires a detailed report on price changes across many product categories and on broader economic effects like investment, jobs, and small‑business health. The findings must be sent to Congress within a year, with confidential data redacted.

Key Provisions

  • The U.S. International Trade Commission must investigate and report to Congress on how proposed 25% tariffs on Mexican and Canadian imports and 10% tariffs on Canadian energy would affect U.S. consumer prices.
  • The report must also examine how any retaliation by Mexico or Canada—such as counter‑tariffs or export limits—could impact U.S. consumers, small businesses, farmers, and ranchers.
  • It must assess the broader business effects of the mere threat of such duties, including impacts on investment, job creation, contract stability, small‑business health, and producer prices.
  • The report must include detailed price analyses for categories like food, energy, critical minerals, vehicles, housing, medical goods, apparel, electronics, farming inputs, and defense manufacturing, plus a qualitative (and where possible quantitative) look at business impacts.
  • The commission must deliver the report to Congress within one year of the law’s enactment, removing any confidential business information before release.
