President Trump imposes new 30% tariffs on Mexican and EU imports effective August 1, warning that any retaliatory measures will be matched and added to the base rate

President Donald Trump on Saturday threatened duties of 30% on products from Mexico and the European Union, two of America’s biggest trading partners, in an ongoing tariff campaign that’s upended global trade since he retook office in January.

While Mexico was spared from Trump's so-called "Liberation Day" tariff rollout on April 2, the 30% rate for the E.U. is 10% higher than what the president said he would apply to America's largest trading partner in April.

The president posted letters to his EU and Mexican counterparts on his Truth Social account on Saturday morning.

In a letter to Mexico’s president, Claudia Sheinbaum, Mr. Trump said that Mexico was not doing enough to curb the flow of fentanyl into the United States and cited that as the reason for the tariffs. Mr. Trump added that Mexican companies were welcome to manufacture their products in the United States to avoid the tariffs.

Mexico did not face a new tariff on April 2, the day of Trump's so-called "Liberation Day" tariff rollout. There remains a 25% tariff on non-USMCA-compliant goods from Canada and Mexico, as well as a 50% tariff on steel, aluminum and derivative products.

Canada would bear the brunt of Trump's tariffs in terms of economic contraction, says The Budget Lab of Yale.

President Trump announced in a letter posted to social media on Saturday that he would place a 30 percent tariff on goods from the European Union, upending months of careful negotiations and further roiling what is one of the world’s most important economic relationships.
