S. 959: Tariff Transparency Act of 2025

This bill requires the U.S. International Trade Commission to investigate and report to Congress on the impact of additional tariffs on imports from Canada and Mexico. (President Donald J. Trump issued executive orders on February 1, 2025, to impose an additional 25% tariff on most imports from Canada and Mexico. These tariffs applied to all imports, except for Canadian energy or energy resources, which have an additional 10% tariff.)

Specifically, the report must assess (1) the impact of these tariffs on consumer prices; (2) the impact of any retaliation (e.g., retaliatory tariffs and export restrictions) imposed by Canada and Mexico on U.S. consumers, small businesses, farmers, and ranchers; and (3) the impact of the threat of tariffs and associated uncertainty with respect to the trade relationship between the United States, Canada, and Mexico on U.S. businesses.
