WASHINGTON D.C January 12, 2026 – U.S. President Donald J. Trump announced on Monday that the United States will impose a 25% tariff on any country conducting business with the Islamic Republic of Iran, effective immediately. The move aims to increase economic pressure on Tehran amid a violent crackdown on widespread anti-government protests.
In a statement posted on social media and shared by the official White House account on X (formerly Twitter), Trump declared: “Effective immediately, any Country doing business with the Islamic Republic of Iran will pay a Tariff of 25% on any and all business being done with the United States of America. This Order is final and conclusive. Thank you for your attention to this matter!” The announcement was signed “PRESIDENT DONALD J. TRUMP.”
The policy represents a form of secondary sanctions, targeting third-party nations that trade with Iran rather than Iran directly. Major trading partners such as China, which remains one of Iran’s largest buyers of oil, could be significantly impacted. Other countries with economic ties to Iran, including India and Turkey, may also face the tariffs.
The announcement comes as Iran grapples with escalating protests that have entered their third week, with reports of hundreds of deaths during the government’s response. Activists and international observers have described the demonstrations as among the most significant challenges to the regime in recent years.
White House officials have not yet provided additional details on implementation, enforcement mechanisms, or specific exemptions. Requests for comment from the administration went unanswered as of early Tuesday.
The tariffs align with Trump’s long-standing “maximum pressure” approach toward Iran, echoing policies from his first term aimed at curbing Tehran’s nuclear ambitions, ballistic missile program, and regional influence.
Global markets reacted cautiously in early trading, with analysts noting potential ripple effects on energy prices and international trade relations. Further developments are expected as affected countries respond.
