US imposes new 50% tariffs on $20 billion worth of Canadian products

Overview of the US-Canada Tariff Dispute
July 20 (Reuters) - President Donald Trump unveiled 50% tariffs on a wide range of imports from Canada on Monday in response to what the U.S. administration called its discriminatory treatment of American-made cars, alcohol and dairy goods, threatening a new front in a global trade war.
Details of the New Tariffs
In slapping import taxes on goods ranging from wine to cement and ice hockey gear, Trump invoked Section 338 of the Tariff Act of 1930, which permits a president to impose punitive tariffs of up to 50% against trading partners deemed to have discriminated against U.S. goods. That marked the law's first known usage in nearly a century of existence.
The new tariffs, set to take effect in 30 days, would also apply to dairy products, swimming pools, furniture, fishing rods, seeds, clothing and wigs, among other items.
The U.S. Trade Representative's office said that the tariffs would apply to nearly $20 billion of imports from Canada. That's about 5.2% of the $382 billion worth of goods that the U.S. imported from Canada in 2025, according to U.S. Census Bureau data.
US Administration's Justification
"While the Administration continues to secure fair and reciprocal trade deals with our trading partners, Canada, unlike other partners and allies, continues to retaliate against the United States for its efforts to rebalance trade and protect U.S. industry in national-security sensitive sectors," U.S. Trade Representative Jamieson Greer said in a statement.
Canadian Response
Canadian Prime Minister Mark Carney said in a statement that his government has made comprehensive proposals to resolve trade disputes with Washington, asserting that Trump's past tariffs violated the North American trade pact.
"This trade dispute has raised costs for families, particularly in the U.S.," he said. "Canada stands ready to engage intensively to address outstanding issues with the U.S. to the mutual benefit of our citizens."
Background and Ongoing Negotiations
The Trump administration has long complained that Canada and China implemented retaliatory measures in response to the barrage of tariffs Trump has tried to impose since returning to the White House last year.
Greer has pointedly left Canada out of negotiations under way with Mexico on changes the U.S. wants in the U.S.-Mexico-Canada Agreement on trade. He holds bilateral talks on USMCA in Mexico City this week.
Recent High-Level Meetings
When Trump and Carney met at the FIFA World Cup Final in New Jersey on Sunday, Trump demanded that Carney take action to contain wildfires that have sent smoke billowing across swaths of the U.S. The U.S. president last week threatened to add the "incalculable cost" of dealing with the pollution to existing tariffs on Canadian goods.
Historical Context and Legal Basis
First Usage of Section 338
FIRST USAGE
The Tariff Act of 1930 and its Section 338 are better known for massive U.S. tariff increases and subsequent retaliation that economic historians say worsened the Great Depression of the 1930s.
Section 338 was intended to ensure countries apply tariffs equally and don't give preferential rates to some countries at the expense of U.S. exports, said John Veroneau, a U.S. trade official in President George W. Bush's administration who has extensively researched the statute.
He said that some presidents, including Franklin D. Roosevelt, considered imposing tariffs under Section 338, but no record could be found of any president taking such action until Trump's proclamations on Monday.
Expert Commentary
"It is ironic, to say the least, to use this authority to impose tariffs to retaliate against tariffs that were imposed in response to actions taken by the U.S.," said Veroneau, senior counsel with the Covington and Burling law firm.
"These tariffs may be lawful under Section 338, but they at a minimum violate the spirit of Section 338, which was to create a world where countries apply the same tariffs on the same goods to all countries," he said, adding Trump has moved away from this principle "in a maximalist way."
Post-War Trade Systems
After World War Two, major countries created the "most-favored-nation" tariff system through the General Agreement on Tariffs and Trade to try to prevent a return to the pre-war "beggar-thy-neighbor" economic policies marked by competitive trade restrictions and currency devaluations.
Implications and Exemptions
Tariff Implementation and Exemptions
Trump's new levies are set to take effect on August 19 and apply regardless of whether goods qualify for tariff exemptions under USMCA, although Trump exempted a range of key goods including energy, potash, fish, critical minerals and products already covered by Section 232 tariffs.
Key Issues Cited by the White House
Among grounds for the tariffs, the White House cited Canada's "protectionist" dairy supply management system as well as tariffs and quotas on cars imported to Canada from the U.S. but not from other countries. Carney said that Canada "as is its right, merely matched" U.S. tariffs on the auto sector that were in violation of the USMCA.
Washington also highlighted that most Canadian provinces have halted the sale of U.S. alcohol, which they did in response to prior U.S. tariffs.
The White House said Canadian imports of U.S. motor vehicles dropped by 22% and of U.S. alcoholic beverages by 81% over the past year.
Provincial Authority in Canada
Diamond Isinger, a former senior adviser to ex-Prime Minister Justin Trudeau on U.S.-Canada relations, said Carney would have limited ability to compel provinces to start selling American alcohol again.
“Unless there are some sort of extraordinary measures invoked here, the premiers of those provinces are the ones who decide whether to restock alcohol,” Isinger said.
