During his second term as President of the United States, Donald Trump enacted a series of steep tariffs affecting nearly all goods imported into the country. From January to April 2025, the overall average effective US tariff rate rose from 2.5% to an estimated 27%—the highest level in over a century. After changes and negotiations, the overall average effective tariff rate was 16.8% as of November 2025. US tariff revenue was $287 billion in 2025, a 192% increase from 2024.
Under Section 232 of the 1962 Trade Expansion Act, Trump raised steel, aluminum, and copper tariffs to 50%. He introduced a 25% tariff on imported cars from most countries and a 100% tariff on some pharmaceuticals.
