President Donald Trump has maintained a consistent focus on imposing tariffs on the United States’ trading partners, both allies and adversaries, with the goal of reducing trade deficits and revitalizing manufacturing. However, the outcomes have not met these objectives, as manufacturing job losses persisted for the third consecutive year, according to the Bureau of Labor Statistics.

While the economic impact remains, the legal basis for these tariffs has evolved. After the Supreme Court struck down the use of reciprocal tariffs under the International Emergency Economic Powers Act, Trump introduced a broad 10 percent global tariff relying mainly on Section 122 of the Trade Act of 1974. This tariff is set to expire soon, prompting the administration to propose new duties of 10 to 12.5 percent on imports from 60 countries linked to goods produced with forced labor.

The Office of the U.S. Trade Representative plans to invoke Section 301 of the Trade Act of 1974, which permits investigations and retaliations against trade practices that violate agreements or harm U.S. commerce. This section was previously used in Trump’s first term to impose tariffs on China and the European Union, withstanding multiple court challenges.

Tariff rates increased notably during the period when the International Emergency Economic Powers Act tariffs were active, rising from an average of 2.4 percent in 2024 to 7.7 percent in 2025. Overall, U.S. tariff policy has undergone more than 50 changes since April 2, as reported by the Tax Foundation.

Despite accusations of a short attention span, Trump has demonstrated unwavering commitment to his tariff strategy, though the legal justifications have shifted over time.
