The president on Thursday is expected to outline reciprocal tariffs on nations that have imposed levies on U.S. exports, the White House said.

William Reinsch, senior fellow at the Center for Strategic and International Studies, said Trump officials could opt for a more easily implemented flat 10% or 20% tariff rate, or a messier approach that would require separate tariff schedules matching U.S. tariffs to each other country's rates.

President Donald Trump’s desire to get even on countries by matching tariffs they have on American goods could come at a steep cost.
