US President Donald Trump has announced that countries supplying Iran with military weapons will face immediate 50% tariffs on all goods sold to the United States, with no exemptions. This move comes hours after Trump agreed to a two-week ceasefire with Tehran.In a social media post, Trump stated that 'A Country supplying Military Weapons to Iran will be immediately tariffed, on any and all goods sold to the United States of America, 50%, effective immediately. There will be no exclusions or exemptions!'However, experts have raised questions about the legal authority behind Trump's announcement, as the Supreme Court struck down his use of the International Emergency Economic Powers Act (IEEPA) to impose broad global tariffs in February. The IEEPA has been used extensively for decades to back financial sanctions against Iran, Russia, and North Korea.Rachel Ziemba, adjunct senior fellow at the Center for a New American Security, told Al Jazeera that 'it's a lot more complicated to do that after IEEPA was struck down. There's no immediate policy lever and authorisation that is available for the US to do that. So they need either an act of Congress or need to adapt some other trade tool.'Trump did not specify which countries could face punitive tariffs, but China and Russia have helped Iran build military capacity to counter US and Israeli pressure. The US imports from Russia have fallen sharply since the invasion of Ukraine in 2022 and the wave of financial sanctions imposed on Moscow.Josh Lipsky, vice president and chair of international economics at the Atlantic Council, said that 'this is a China-related threat, the way I read it. And China will read it that way.' However, he also noted that Trump was unlikely to follow through with new tariffs in the near term because that would derail his planned trip to Beijing to meet with Chinese President Xi Jinping in mid-May.
