A proclamation signed by Donald Trump provides for removing some products imported from Canada from the goods subject to a 50% tariff.
The decision was made less than two weeks before the midterm elections scheduled for November 3 in the United States and will take effect on October 30. The White House fact sheet said the measure covers plywood sheets, certain paper products, specific machinery and refrigeration equipment, packing crates and certain types of boxes.
Under the same change, some valves, carpets, waste materials and certain other goods will be added to the tariff list. The White House said the measure aims to better serve the public interest and offset what it described as Canada's discriminatory treatment of U.S. trade.
Exception for nine product categories used by Maine producers
Republican Senator Susan Collins of Maine, where the reelection race is highly competitive, said in an announcement before the White House statement that an exception would be granted for nine product categories used by the state's blueberry, potato, apple and seaweed producers.

Collins said farmers and producers in Maine need specialized equipment, packaging materials and certain other products supplied by Canada. The senator said replacing these products with U.S. alternatives would be difficult or costly, adding that she had asked administration officials to reduce the tariffs and called for work toward a more comprehensive trade agreement with Canada.
Trump had previously said that Canada was making intensive efforts to reach a trade agreement with Washington.
