The issue in plain English
Should the U.S. use tariffs as a primary tool of trade policy?
Tariffs have moved from a secondary lever to a central feature of U.S. trade policy, including in a new U.S.–EU agreement capping most duties on European goods at 15%. Supporters say tariffs can shield domestic industries and raise federal revenue, while critics contend they raise costs for businesses and consumers and invite retaliation. The debate turns on competing readings of economic evidence and the proper balance of power between Congress and the president.

The arguments
Two sides of the debate.
The goal is not to decide for the voter. It is to make the strongest competing views easy to understand.
Supporters say
The case for tariffs as a primary tool
Supporters argue tariffs protect domestic manufacturing from foreign competition that benefits from lower wages, weaker environmental rules, or state subsidies. By raising the price of imports, tariffs can give U.S. producers room to invest, hire, and maintain capacity in industries seen as strategically important, such as steel, semiconductors, and autos. Proponents also point to revenue and leverage. The Tax Foundation estimated in 2025 that broad new U.S. tariffs would raise hundreds of billions of dollars over a decade. Backers say that revenue, combined with the threat of higher duties, has helped bring trading partners to the table, citing the U.S.–EU cap as an example of negotiated terms that might not have been reached without tariff pressure.
Critics say
The case against relying on tariffs
Critics argue tariffs function as a tax that is paid in the first instance by U.S. importers and often passed on to consumers and downstream businesses through higher prices. They contend that while some domestic producers benefit, industries that rely on imported inputs face higher costs, and households see reduced purchasing power. The same Tax Foundation analysis that projected significant revenue also estimated a drag on U.S. GDP growth, though estimates vary by model and assumptions. Opponents also warn of retaliation and uncertainty. Trading partners can impose counter-tariffs on U.S. exports, particularly agricultural goods, and frequent shifts in tariff rates can complicate business planning and investment. Some critics further argue that heavy reliance on executive tariff authority shifts trade policymaking away from Congress, the branch the Constitution assigns the taxing power.

Context
How tariffs fit into U.S. trade policy
The U.S. Constitution gives Congress the power to lay tariffs, but lawmakers have delegated broad authority to the president through statutes such as the Trade Act of 1974 and Section 232 of the Trade Expansion Act of 1962. Recent administrations have used that authority to impose or threaten duties on a range of imports, citing national security, unfair trade practices, and leverage in negotiations. The European Union remains the United States' largest combined trading partner, with bilateral goods and services trade exceeding $975 billion in 2024, according to the U.S. Trade Representative. A new U.S.–EU agreement caps tariffs on most EU exports to the United States at 15%, replacing earlier threats of higher rates and illustrating how tariffs are now being used both as a policy instrument and a bargaining tool.
Evidence
What the data show
Economic studies of recent tariff rounds generally find that most of the direct cost of U.S. tariffs has been borne by U.S. importers and consumers, though effects vary by sector and by how exchange rates and supply chains adjust. Analyses also document gains for some protected industries alongside losses in sectors exposed to retaliation or higher input costs. Revenue and growth projections depend heavily on assumptions about tariff levels, coverage, and behavioral responses. The Tax Foundation's 2025 estimates illustrate the trade-off frequently cited in the debate: meaningful new federal revenue paired with a projected reduction in long-run output. Other models, including those from think tanks and government agencies, produce different magnitudes but often describe a similar mix of fiscal gains and economic costs.
