Trump imposes 10% tariffs on all countries after Supreme Court struck down earlier tariffs

President Trump signed a proclamation Friday evening that will impose 10 percent tariffs on most foreign imports into the United States, just hours after the vote. The Supreme Court overturned a series of drastic global tariffs which were issued under a different legal authority.

The new rates take effect Monday and will be in effect for 150 days, according to a White House fact sheet. Some foreign products are exempt from the 10% duty, including certain imports of food, critical minerals, electronics and cars. Goods from Canada and Mexico covered by a 2018 trade agreement are also not subject to tariffs.

“It is a great honor for me to have just signed, from the Oval Office, a global tariff of 10% on all countries, which will take effect almost immediately,” the president wrote in an article for Truth Social.

The move comes as Mr. Trump attempts to resurrect the global regime of high tariffs and trade deals that are a core part of his economic agenda. Most of its tariffs relied on a law called the International Emergency Economic Powers Act, or IEEPA, which the Supreme Court ruled Friday could not be used to impose tariffs.

Friday’s tariffs were issued under a different law: Section 122 of the Trade Act of 1974. This legal provision allows the president to impose duties of up to 15% for 150 days to address “significant and serious” balance of payments problems.

The new levies are similar to the 10% base tariff rate that Mr. Trump applied to goods from dozens of the United States’ trading partners. since last spring. He says broad tariffs are necessary to close trade deficits and revive U.S. manufacturing, but many economists warn that the costs of tariffs are largely borne by consumers.

Many trading partners faced higher rates under Mr. Trump’s previous tariffs, including a set of “reciprocal” tariffs on a litany of countries and levies on many products from China, Canada and Mexico linked to drug trafficking concerns. Some countries have negotiated lower rates as part of broader trade deals. But those measures relied on the Trump administration’s interpretation of IEEPA, which was struck down by the high court on Friday.

It is unclear whether the administration will attempt to reinstate these higher tariff rates. Asked if his trade deals were still in effect, Mr. Trump told reporters Friday: “Some of them are in effect. A lot of them are in effect. Some of them won’t be in effect, and they will be replaced by the other tariffs.”

Mr. Trump also ordered the office of the US Trade Representative, Jamieson Greer, to open investigations into “certain unreasonable and discriminatory acts, policies and practices that burden or restrict American commerce” under Section 301 of the Trade Act, the White House said. This law allows the government to impose tariffs and other measures to correct unfair trade practices.
