WASHINGTON — President Donald Trump signed an executive order on Friday that establishes a framework for imposing additional tariffs on countries maintaining trade relations with Iran. The order follows a series of public statements regarding U.S. economic pressure on Tehran. Key Provisions of the Order The executive order provides the U.S. government with the authority to levy additional ad valorem duties on imports from any nation that “directly or indirectly purchases, imports, or otherwise acquires any goods or services from Iran.” Tariff Rate: While the order does not mandate a specific percentage, it cites 25% as a primary example for potential implementation. Administrative Oversight: The Secretaries of State and Commerce, along with the U.S. Trade Representative, are authorized to implement the system and issue specific guidance. Flexibility Clause: The President maintains the authority to modify or waive these duties based on changes in international circumstances or if a country aligns its policies with U.S. national security interests. Context and Objectives The White House characterized the measure as a response to an “unusual and extraordinary threat” to national security. The administration stated the goal is to hold the Iranian government accountable for its nuclear program, ballistic missile development, and regional activities. The signing comes as U.S. and Iranian officials engage in ongoing diplomatic discussions in Oman. During remarks from Air Force One on Friday evening, President Trump did not detail the order but reiterated his stance that Iran must not acquire nuclear weapons. Background The policy follows a January 12 post on Truth Social where the President first proposed a 25% tariff on any country doing business with the Islamic Republic. This action mirrors similar “maximum pressure” tactics used in early 2026 regarding trade with Cuba and Venezuela.
