The White House plans to begin levying the import penalties on June 10 and ratchet the penalties higher if the migrant flow isn’t halted. Trump said he would remove the tariffs only if all illegal migration across the border ceased, though other White House officials said they would be looking only for Mexico to take major action.
After the 5 percent tariffs are imposed on June 10, the White House said it would increase the penalties to 10 percent on July 1 and then an additional 5 percent on the first day of each month for three months. The tariffs would stay at 25 percent “until Mexico substantially stops the illegal inflow of aliens coming through its territory,” a statement by the president said.
