President Trump’s latest tariff strategy, announced June 2 under Section 301 of the Trade Act of 1974, uses forced labor allegations to achieve what the Supreme Court took away from him: a broad wall of tariffs around the American economy.
The Supreme Court ruled 6-3 on February 20 that the International Emergency Economic Powers Act does not authorize the president to impose sweeping tariffs. The decision struck down Trump’s “Liberation Day” tariffs and sent his trade team scrambling for a legal basis to continue what had become the centerpiece of his economic agenda. The question now is whether the forced labor workaround can survive the legal and diplomatic challenges that are already taking shape.
The Trump administration’s answer to the court was swift. Trump imposed a temporary 10 percent global tariff in March, set to expire July 24. But the real long-term play came on June 2, when the Office of the United States Trade Representative announced a new investigation under Section 301 targeting 60 economies, including the European Union, the United Kingdom, Canada, and Australia, over alleged failures to address forced labor in their supply chains. The proposed remedy: tariffs of up to 12.5 percent on imports from countries that do not pass laws banning forced labor imports.
At first glance, the strategy is clever. Section 301 gives the USTR broad authority to investigate and retaliate against foreign trade practices that are “unreasonable or discriminatory.” Forced labor has been a legitimate concern in global supply chains for years, and Congress has shown bipartisan support for action against it. By framing tariff policy as human rights enforcement, the administration hopes to ground its protectionism in statutory authority that the courts have consistently upheld.
But trade analysts and legal scholars are already raising serious questions. The investigation began in March and was fast-tracked specifically to provide legal cover for reimposing tariffs after the Supreme Court ruling. The target list includes countries that have no known forced labor crisis. It includes close US allies who have been cooperating with Washington on trade issues. This suggests the real purpose is not combating forced labor but maintaining Trump’s protectionist wall.
“Section 301 gives the president more latitude than IEEPA, but it is not a blank check,” said one trade law expert cited in recent coverage. “The countries targeted will challenge this at the World Trade Organization and likely in US courts. The forced labor rationale is thin for many of these economies, and a judge will eventually ask whether the administration is acting in good faith or simply trying to circumvent a Supreme Court ruling.”
The costs are already accumulating. The United States’ effective tariff rate now stands at roughly 10.5 percent, the highest since 1943 outside of the 2025 period. Trump’s original Liberation Day tariffs wiped out an estimated 89,000 manufacturing jobs, according to a cryptobriefing analysis. The new Section 301 strategy threatens to deepen that damage by drawing retaliation from dozens of countries simultaneously.
The diplomatic cost may be even steeper. The European Union, UK, Canada, and Australia are not accustomed to being treated as targets of US trade enforcement actions. All four diplomatic partners have signaled that they will respond with their own retaliatory tariffs if the United States follows through on the proposed 12.5 percent levy. Trade analysts predict this could accelerate the “reorientation” of global trade away from the United States, pushing America’s closest partners to deepen their own trade relationships with each other and with China.
The strategy also opens Trump to the charge of cynicism. By invoking forced labor, a genuine humanitarian concern, as a pretext for tariffs, the administration risks delegitimizing real efforts to address forced labor in global supply chains. Human rights groups have expressed concern that Trump’s trade war will taint legitimate enforcement with the stain of protectionist abuse.
So how long before the workaround fails? The WTO challenge will take years to resolve, but legal challenges in US courts could move faster. Plaintiffs will argue that the Section 301 process is being used in bad faith to circumvent a Supreme Court ruling. If a federal judge agrees, the tariffs could be blocked as early as late 2026 or early 2027. In the meantime, the temporary 10 percent tariff expires July 24, and the administration needs the Section 301 mechanism operational by then to avoid a gap in coverage.
The July 24 deadline creates a pressure cooker. The USTR must complete its forced labor investigation, secure findings against 60 countries, and implement tariff schedules in just over a month. That pace alone invites legal vulnerability. Procedural shortcuts meant to beat the July deadline will be the first thing litigators target.
For American consumers, the costs are immediate. Import prices are rising, retailers are passing on higher costs, and the Federal Reserve has noted that tariff uncertainty is contributing to persistent inflation. For American allies, the message is clear: Washington will use any tool it can find to keep tariffs in place, even at the expense of its relationships with partners.
The forced labor tariff strategy is a workaround, and like most workarounds, it is temporary. Whether it collapses in court, at the WTO, or under the weight of allied retaliation, the underlying question remains unanswered: can the United States maintain a protectionist trade policy without a sustainable legal basis? The Supreme Court said no in February. Trump is betting that a creative reading of Section 301 can change the answer. The evidence so far suggests otherwise.
