New York, Feb 21 (AP) The nation's highest court struck down some of US President Donald Trump's most sweeping tariffs on Friday, in a 6-3 decision that he overstepped his authority when using an emergency powers law to justify new taxes on goods from nearly every country in the world.

Trump has launched a barrage of new tariffs over the last year. Despite Friday's ruling, many sectoral levies remain in place — and the president has already said that he'll turn to other options for more import taxes, including plans to impose a new 10 per cent tariff globally. But the Supreme Court decision upends a core set of tariffs that Trump rolled out using the 1977 International Emergency Economic Powers Act, or IEEPA.

IEEPA authorizes the president to broadly regulate commerce after declaring a national emergency. Over the years, presidents have turned to this law dozens of times, often to place sanctions on other countries. But Trump was the first to use it to implement tariffs.

Here's a look at the now-overturned tariffs Trump imposed using IEEPA — and other levies that still stand today.

Liberation Day' tariffs ----------------------- Trump used IEEPA to slap import taxes on nearly every country in the world last spring. On April 2, which Trump called Liberation Day, he imposed “reciprocal” tariffs of up to 50% on goods from dozens of countries — and a baseline 10 per cent tariff on just about everyone else.

The 10 per cent tax kicked in early April. But the bulk of Liberation Day's higher levies got delayed by several months, and many rates were revised over time (in some cases after new “framework” agreements). Most went into effect Aug. 7.

The national emergency underlying these tariffs, Trump argued at the time, was the long-running gap between what the US sells and what it buys from the rest of the world. Still, goods from countries with which the US runs a trade surplus also faced taxes.

Major trading partners impacted by Liberation Day tariffs include South Korea, Japan and the European Union — which combined export a range of products to the US, like electronics, cars and car parts and pharmaceuticals. Following trade talks, Trump's rates on most goods stood at 15 per cent for the EU, Japan and South Korea ahead of Friday. But just last month, Trump threatened to hike levies on certain South Korean products to 25 per cent — and countries worldwide still face sector-specific, non-IEEPA tariffs.

Trafficking tariffs' on Canada, China and Mexico ------------------------------------------------- At the start of his second term, Trump used IEEPA to impose new tariffs on America's three biggest trading partners: Mexico, Canada and China.

To justify these tariffs, Trump declared a national emergency ostensibly over undocumented immigration and the trafficking of drugs like fentanyl and the chemicals made to use it. The levies were first announced at the start of February 2025, but went into effect over time — and were at times delayed, reduced or heightened through further retaliation.

Ahead of Friday's decision, “trafficking tariffs” on Canadian and Mexican imports were 35 per cent and 25 per cent, respectively, for goods that don't comply with the 2020 United States-Mexico-Canada Agreement. China, meanwhile, faced a 10% fentanyl-related tariff. That's down from 20 per cent imposed by Trump earlier last year. Chinese goods also once saw sky-high levies after Liberation Day, but rates had since come down during trade talks.

Top US imports from China include mobile phones and other electronics, as well as clothing, toys and household appliances. Meanwhile, Canada and Mexico are both major sources of cars and auto parts. Canada is also the US's largest supplier of crude oil. And Mexico is a key exporter of fresh produce, beverages and more.

Tariffs on Brazil over Bolsonaro trial -------------------------------------- Trump also used IEEPA to slap steep import taxes on Brazilian imports over the summer, citing the country's policies and criminal prosecution of former President Jair Bolsonaro.

Brazil already faced Trump's 10 per cent baseline Liberation Day rate. The Bolsonaro-related duties added another 40%, bringing total levies to 50 per cent on many products ahead of Friday.

The U.S. has actually run a consistent trade surplus with Brazil over the years. But top exports from the country include manufactured products, crude oil and agricultural products like soybeans and sugar.

Tariffs on India linked to Russian oil ------------------------------------- India has faced additional IEEPA tariffs, too. After Liberation Day, Trump slapped a 25% levy on Indian imports — and later added another 25 per cent for the country's purchases of Russian oil, while also citing the emergency powers law, bringing the total to 50 per cent.

But earlier this month, the US and India reached a trade framework deal. Trump said Prime Minister Narendra Modi agreed to stop buying Russian oil, and that he planned to lower U.S. tariffs on its ally to 18 per cent. Meanwhile, India said it would “eliminate or reduce tariffs” on all US industrial goods and a range of agricultural products.
