Trump has rolled back many of his steepest tariffs over recent months, including a sky-high levy on China, the top source of U.S. imports. In recent days, however, Trump announced plans to slap tariffs as high as 50% on dozens of countries, including 25% tariffs on top U.S. trade partners such as Japan and South Korea.

With the Trump administration setting 15% as a floor for tariffs, companies and economists are warning of higher prices later this year.
