The United States announced changes Friday that would exempt certain Canadian imports from 50% tariffs, a move intended to provide political support to Maine Republican Sen. Susan Collins and other GOP candidates ahead of the upcoming midterm elections.
According to documents published on the White House website, the administration will eliminate duties on selected agricultural equipment and related goods, including specific machinery, refrigeration equipment, packaging materials and plywood sheets. However, the government will simultaneously introduce 50% tariffs on additional Canadian imports, among them carpets, certain types of valves and waste materials.
The revised tariff measures are scheduled to take effect on Oct. 30.
Following initial reports of the policy adjustment by The Wall Street Journal, Collins released a statement welcoming the administration’s decision to provide relief from the import duties.
“I have asked for tariff relief for these important products and stressed the burdens additional costs impose on Maine businesses and families,” Collins said. “I will continue working directly with Administration officials to seek additional relief from tariffs and encourage a broader trade agreement with Canada, our neighbor, ally, and largest trading partner.”
Collins has publicly disagreed with President Donald Trump’s tariff policies while seeking another Senate term in Maine, where economic activity is closely connected to cross-border commerce with Canada. Her Democratic opponent, Troy Jackson, has placed Trump’s trade dispute with Canada at the center of his campaign. Polling indicates a closely contested race between the two candidates as Election Day approaches.
In late August, Trump introduced 50% duties on approximately $20 billion in Canadian imports, representing around 5% of Canada’s total exports to the United States, after negotiations between the neighboring countries collapsed shortly before a potential agreement. Canada responded by imposing retaliatory tariffs, prompting Trump to prohibit imports of certain Canadian products. He also warned that tariffs on Canadian automobiles could double in January unless the two governments reached a trade agreement.
The latest announcement marks the second adjustment to the administration’s 50% tariffs on Canadian products. Last month, Washington removed import duties on goods such as road salt and cement, a decision Collins highlighted during her reelection campaign as a result of her efforts. Jackson continued criticizing the administration’s trade policies despite those exemptions, arguing during a debate with Collins this month that Maine residents “can’t eat road salt.”
When the administration previously lifted tariffs on selected Canadian goods, it compensated by extending the 50% duties to other imports, maintaining the overall value of affected Canadian exports at approximately $20 billion. The newly announced tariffs on carpets, valves and waste products are expected to serve the same purpose, keeping the total value of Canadian goods subject to the higher duties close to $20 billion.
Although Collins had specifically requested the tariff adjustments, the changes could also offer political benefits to Republican candidates competing in other states with substantial commercial ties to Canada. In Michigan, former Rep. Mike Rogers, the Republican Senate nominee, has released campaign advertisements urging Trump to end the trade dispute with Canada, reversing his earlier support for the president’s policies. Similarly, former Sen. John Sununu has criticized the administration’s Canadian tariffs while campaigning in New Hampshire against Democratic candidate Chris Pappas.
Trump imposed the 50% tariffs using Section 338 of the Tariff Act of 1930, commonly associated with the Smoot-Hawley legislation, a trade provision that had never previously been invoked. This week, a food-importing company based in New Jersey challenged the tariffs in court, alleging that the administration had exceeded its statutory authority by imposing the duties.
