On Sept. 8, President Trump signed an executive order to outright ban some Canadian dairy products from entering the U.S.
Section 338 of the Tariff Acts of 1930 grants the president this authority.
Additional executive orders, which comes into effect Sept. 29, include motorcycles and alcohol.
This collection of moves is in response to Canada's latest round of tariffs against the U.S., which took effect at midnight on Sept. 8.
