Trump’s new temporary global tariffs take effect

President Donald Trump’s revamped temporary global tariffs took effect on Tuesday, imposing a blanket 10% levy on most goods imported into the United States. To levy the new tariffs, Trump used a section of the Trade Act of 1974, which allows him to address international payment problems through surcharges and import restrictions.

How do these tariffs work? The new tariffs will only last for 150 days unless extended by Congress. The president on Monday said he didn’t intend to seek congressional approval, so his administration will likely need to use another law to institute tariffs after the new 150-day levies expire. Trump also said over the weekend that he intended to raise the new temporary tariffs to 15%, but he didn’t appear to have made that change by Tuesday morning.

The move came after the Supreme Court on Friday struck down most of Trump’s global tariffs under the International Emergency Economic Powers Act of 1977. The court said Trump didn’t have the authority to impose tariffs under that act without congressional approval, but he could legally use other legislation to levy tariffs.
