A federal appeals court just ruled that most of President Trump’s “reciprocal tariffs” are illegal because he went beyond his legal power as president. These tariffs were huge. They covered almost 70% of U.S. imports and charged other countries, like Mexico, Canada, China, India, and Brazil, up to 50% on goods. The court said only Congress can create taxes like tariffs, not the president. For now, the tariffs will stay in place until mid-October while Trump appeals to the Supreme Court. If the Court agrees with the ruling, Trump can still put tariffs in place but only in smaller amounts and for shorter time periods using a different law.
Some of Trump’s tariffs are still safe. His taxes on steel and aluminum (called Section 232 tariffs) are not affected by the ruling and were recently expanded to cover more products. These tariffs are likely to stay even if the Supreme Court removes the bigger ones. Other tariffs that started during Trump’s first term on China also remain, along with a new rule that removes the $800 “free pass” for small imports, meaning even cheap goods from overseas now face extra costs. This all means Trump might shift to using more focused, industry-specific tariffs instead of taxing almost all imports.

This case shows how economic policy is shaped by the balance of power between the president, Congress, and the courts and how trade policy can have big effects on global markets and domestic businesses.
