A slew of countries will face steep levies, including a 50% tariff on imports from Brazil and a 30% tariff on the European Union.

Montana ranchers, farmers and the state’s tourism industry expressed deep concern with President Donald Trump’s tariffs during a press call on Thursday. Uncertainty is a major issue, they said, and the actions have set the United States up as an “unreliable trade partner” which is damaging to those who depend on markets outside the country.

The move injects fresh turmoil into a strained bilateral relationship as Prime Minister Mark Carney negotiates a new economic partnership with the United States.

President Donald Trump said he is considering rebates to US taxpayers from billions in tariff revenue flowing into the country.

President Trump’s new levies, which have pushed the country’s tariffs to their highest levels in decades, are typically paid by importers when goods reach U.S. ports. So there is little mystery about who makes that first payment.
