In a significant ruling on Friday, the U.S. Supreme Court deemed President Donald Trump’s tariffs on Canada and various countries illegal, yet the decision does not mark the end of his controversial trade policies. The judgement specifically targets the tariffs implemented under emergency powers, including the contentious “reciprocal” tariffs and those connected to fentanyl imports from Canada. While this ruling curtails Trump’s authority to impose additional tariffs at will, it leaves intact numerous other tariffs that have been levied on key sectors such as steel and aluminium.
Tariffs Under Fire
The Supreme Court’s decision arose from lawsuits challenging Trump’s application of the International Emergency Economic Powers Act (IEEPA). This 1977 statute permits the president to regulate economic transactions in times of emergency. Trump had claimed the authority to impose tariffs in response to two emergencies he declared early last year: one concerning fentanyl trafficking from Canada, Mexico, and China, and another regarding significant trade deficits with multiple nations.
At the time of the ruling, Canadian products faced a substantial 35 per cent tariff under the fentanyl-related measures, while goods like energy and fertiliser were subject to a reduced rate of 10 per cent. However, many Canadian exports, approximately 85 per cent, were exempted from these tariffs due to provisions outlined in the Canada-U.S.-Mexico Agreement (CUSMA).
“The implications for domestic stakeholders are intriguing, as they lose that preferential access under the zero per cent rate,” noted Robert Glasgow, an international trade lawyer based in Toronto. “Yet, the compliance with the rules of origin necessary to retain that rate can be costly and complex, so these compliance costs are likely to decrease.”
Remaining Tariffs and Future Actions
Despite the Supreme Court’s ruling, several sector-specific tariffs imposed under Section 232 of the U.S. Trade Expansion Act remain in effect. This legislation allows the president to tackle excessive foreign imports that threaten national security. The tariffs currently in place include a staggering 50 per cent on steel and aluminium, and a 25 per cent duty on automobiles and certain auto parts that do not meet CUSMA requirements. Additionally, the softwood lumber sector faces a 10 per cent tariff, layered atop existing anti-dumping duties.
In light of the court’s decision, Trump announced his intent to enact a new 10 per cent global tariff using Section 122 of the U.S. Trade Act. This section allows the president to address trade deficits but limits the tariff to a maximum of 15 per cent for 150 days unless extended by Congress. Furthermore, Trump indicated that his administration would initiate several investigations under Section 301 of the Trade Act, which has previously targeted nations like China for perceived unfair trade practices.
Uncertainties and Refunds
One pressing question following the Supreme Court’s ruling concerns whether American businesses that paid the now-illegal tariffs will receive refunds. Trump remarked on the substantial revenue generated from these tariffs, stating, “We’ve taken in hundreds of billions of dollars. Wouldn’t you think they would have put one sentence in there saying (either) keep the money or don’t keep the money?”
The Penn-Wharton Budget Model estimated that the U.S. government collected approximately $164.7 billion from IEEPA tariffs, comprising over half of all customs duties since January. Businesses like Costco have already initiated lawsuits to secure refunds if the tariffs are invalidated.
Dan Anthony, executive director of We Pay the Tariffs, a coalition of small U.S. businesses involved in the Supreme Court case, emphasised the need for an efficient refund process. “Small businesses cannot afford to wait months or years while bureaucratic delays play out,” he stated. “They need their money back now.”
Why it Matters
The Supreme Court’s ruling introduces a complex new chapter in the ongoing saga of U.S. trade policy under Trump. While it curtails some of the president’s more aggressive tariff strategies, the persistence of other tariffs and the potential for new ones means that uncertainty will continue to loom over North American trade relations, particularly with Canada. As businesses grapple with the ramifications of the ruling, the broader implications for international trade dynamics and economic stability remain at the forefront of concerns for both policymakers and industry stakeholders alike.
