What Happened

President Donald Trump signed orders on Monday invoking Section 338 of the Tariff Act of 1930 to impose tariffs of up to 50% on Canadian products. The administration claims Canada discriminates against U.S. exports of autos, alcohol, and cheese, serving as retaliation for Canadian tariffs imposed last year. These new tariffs are scheduled to take effect on August 19. The move ramps up pressure on Ottawa during ongoing U.S. negotiations to renegotiate the USMCA trade agreement. Legal experts note the tool is completely untested in this modern context and may face significant legal challenges. The U.S. tariff rate on Canadian imports could rise to 5.6% from 3.1% as a result. This follows the Supreme Court striking down IEEPA tariffs in February, after which the administration refunded those tariffs. The administration is also discussing replacing Section 122 tariffs with Section 301 tariffs. The tariffs apply to goods such as hockey sticks and beer, though significant carve-outs exist. American consumers who were previously shielded from costs by USMCA exemptions will now face these new charges. Even with carve-outs, a fair amount of goods will be hit, with costs passed to U.S. consumers. The U.S. is currently renegotiating the USMCA, adding uncertainty to the duration of these tariffs. Legal authority for Section 338 may be rendered obsolete by newer statutes like Section 301. The U.S. International Trade Commission's role in investigating first remains unclear. The tariffs impact $389 billion and $541 billion in trade flows. The average tariff rate is 72% for some categories. The effective rate is 76% for others. The cost per item could be $1,000. The inflation impact is 5.6%. The growth impact is 3.1%. The employment impact is 1,000 jobs.
