President Donald Trump on Wednesday said the United States would impose sweeping new tariffs on countries that supply military weapons to Iran, linking the threat to enforcement of a newly announced two-week ceasefire between Washington and Tehran.
In a post on Truth Social, Trump stated: “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!”
The warning came one day after the United States and Iran reached a temporary truce. Trump described the talks behind the agreement as involving “very productive regime change” discussions and signaled that U.S. officials would engage directly with Iranian counterparts during the pause in hostilities, wrote CNBC.
In a separate Truth Social message, Trump emphasized that “there will be no enrichment of uranium” under the developing framework and said elements of a broader set of U.S. proposals had already been accepted. He added that the two sides would continue negotiations, including discussions over potential tariff and sanctions relief.
The tariff threat appears aimed at deterring third-party countries from continuing or initiating arms transfers to Iran while the ceasefire remains in effect. The administration indicated the penalties would apply broadly and without delay to any nation found in violation, raising the prospect of economic pressure on major exporters that maintain defense relationships with Tehran.
The ceasefire itself follows weeks of escalating tensions in the region, including concerns over stability in the Strait of Hormuz, a key corridor for global energy shipments. While the pause has been framed by the White House as an opening for broader diplomatic progress, officials have released few details about the full scope of the agreement.
The move reflects a familiar strategy from the administration: pairing a temporary reduction in military activity with the threat of expanded economic measures. Whether the tariff warning alters the behavior of other nations—or complicates ongoing negotiations—remains uncertain, as markets and U.S. allies monitor both enforcement and the durability of the truce.
