President Donald Trump said the United States will impose a 25% tariff on all goods imported from Tunisia, effective Aug. 1. The measure was announced in a formal letter addressed to Tunisian President Kais Saied and published on Trump’s social-media account. The communication did not specify exemptions or the rationale for the new duty. The action adds Tunisia to the list of U.S. trading partners facing higher import levies under the administration’s ongoing tariff policy.
