Washington, D.C., July 22: U.S. President Donald Trump has announced a new 50 per cent tariff on a broad range of Canadian exports by invoking a little-used provision of the U.S. Tariff Act of 1930, a law that has never before been used by any American president for this purpose.
The tariffs, scheduled to take effect on August 19, have intensified trade tensions between Canada and the United States and could face legal challenges from American importers required to pay the higher duties. However, trade law experts believe Trump may have stronger legal authority this time than in previous tariff disputes.
Unlike earlier tariffs that were successfully challenged in U.S. courts, the latest measures rely on Section 338 of the Tariff Act of 1930, commonly known as the Smoot-Hawley Tariff Act. The legislation specifically authorizes the U.S. President to impose tariffs of up to 50 per cent on goods from countries whose trade practices are deemed to discriminate against the United States.
In official proclamations released by the White House, the Trump administration argues that Canada has placed American commerce at a disadvantage through several policies, including:
- Provincial bans on the sale and distribution of U.S. alcoholic beverages.
- Restrictions on American dairy products under Canada’s supply management system.
- Limits on certain U.S. automobile exports to Canada.
According to Simon Lester, a trade law expert with Rice University’s Baker Institute for Public Policy, the wording of Section 338 provides the President with broad authority.
He noted that the law focuses on whether discrimination exists, regardless of whether a country believes its actions are justified. As a result, any legal challenge could face significant hurdles.
John Veroneau, a former Deputy U.S. Trade Representative, said the legislation contains fewer procedural limitations than other U.S. trade laws, making it more difficult to overturn in court. While he expects legal challenges if the tariffs take effect, he cautioned that their success is uncertain.
Despite the legal questions, many analysts believe the tariff announcement is primarily intended to strengthen Washington’s bargaining position in ongoing trade negotiations with Canada.
Prime Minister Mark Carney confirmed earlier this week that he and President Trump had agreed to intensify trade discussions in hopes of resolving the growing dispute before the August implementation date.
The latest measures follow escalating disagreements over Canadian alcohol policies, dairy market protections, and automotive trade, adding further strain to the economic relationship between the two neighbouring countries.
Business groups on both sides of the border have expressed concern that the proposed tariffs could increase costs for manufacturers, disrupt integrated North American supply chains, and negatively affect consumers and exporters in both countries.
Whether the tariffs ultimately take effect or become a negotiating tool remains uncertain. However, the use of Section 338 of the Tariff Act of 1930 marks one of the most unusual and legally significant trade actions undertaken by a U.S. president in decades.
