US raises global tariffs to 15% effective immediately

US President Donald Trump announced a significant increase in tariffs on imported goods from 10 percent to 15 percent “effective immediately,” just hours after the Supreme Court had struck down his sweeping duties. The move came as part of a separate law called Section 122, which allows for up to 15 percent tariffs but requires congressional approval after 150 days.

After Friday’s decision by the Supreme Court that found Trump had overstepped his authority with these tariffs under an economic emergency law, Trump said he would now raise the import levies “to the fully allowed and legally tested 15 percent level.” He stated on his Truth Social platform that after a thorough review of the court’s decision, the administration was making this adjustment to continue its successful strategy to make America great again.

Trump’s tariff policies have been at the heart of the ongoing global trade war he started during his second term as president. These tariffs, which are taxes on imported goods, have not only hurt trading partners but also destabilized financial markets and caused significant economic uncertainty across the globe.

While Canada hailed the Supreme Court ruling for its finding that the levies were never justified, other US trading partners—particularly European nations—remained cautious in their response. The United Kingdom, Germany, and the EU noted they are closely analyzing the court’s decision with the Trump administration.

The tariffs have been a cornerstone of Trump’s economic and foreign policy strategy, expected to generate over $trillions in revenue for the US, which boasts the world’s largest economy. However, the administration has yet to provide tariff collection data since December 14, 2025.
