Tariff Transparency Act of 2025

This proposal tells the U.S. International Trade Commission to study how new or threatened duties (extra charges on imports) on goods from Mexico and Canada could affect people and businesses in the United States. The study must look at possible price changes for everyday items like food, energy, housing materials, medicines, cars and parts, clothing, electronics, and farm supplies. It must also look at what could happen if Mexico or Canada strike back with their own duties or export limits, and how ongoing uncertainty about duties could affect investment, jobs, contracts, small businesses, and producer prices. The Commission must send a public report to Congress, with any confidential business details removed, within one year of the law taking effect .
