U.S. President Donald Trump has introduced sweeping trade measures against nations engaging in commerce with Iran, announcing a 25 per cent tariff on their dealings with America amid intensifying unrest in the Middle Eastern state.
The declaration arrived via a Monday post on Truth Social, where Trump specified that the levy applies to “any and all business being done with the United States of America” and takes effect immediately.
He underscored its binding nature by adding, “This Order is final and conclusive. Thank you for your attention to this matter!” White House spokespeople provided no further details when approached for comment on implementation or targeted countries. Such a policy risks disrupting fragile trade balances, particularly with China as Iran’s top oil customer.
This step unfolds against a backdrop of Tehran’s fierce suppression of widespread anti-government protests, the most significant since the 2022 upheaval, with reports confirming hundreds of deaths and numerous injuries.

Iran’s Foreign Minister Abbas Araghchi insisted the unrest remains under control, attributing it to foreign meddling while highlighting state-backed gatherings.
Trump has pledged military response to further fatalities and rallied behind the demonstrators, declaring on Saturday via social media, “Iran is looking at FREEDOM, perhaps like never before. The USA stands ready to help!!!”
The tariff move precedes a crucial Supreme Court judgement on the validity of Trump’s broader trade actions, such as the early April reciprocal duties and those tied to fentanyl flows, all authorised through the International Emergency Economic Powers Act.
Legal challenges argue this statute oversteps presidential bounds on tariffs, a power reserved for Congress. Questions linger over whether the Iran-specific tariffs draw on the same legal foundation, potentially reshaping international commerce.
