The Trump administration imposed new tariffs on more than 80 countries' goods under Section 301 of the Trade Act of 1974, accusing those countries of failing to effectively eliminate forced labor practices. These tariffs impact trade partners representing 99.4% of U.S. trade and were introduced shortly after earlier tariffs expired due to a Supreme Court ruling that invalidated the broad "liberation day" tariffs Trump had previously enacted under the International Emergency Economic Powers Act (IEEPA). The new duties mark a shift, prompting debate among legal and trade experts due to the unprecedented scope and permanence of the tariffs.

Experts suggest that Trump’s invocation of Section 301 for these sweeping tariffs stretches beyond the original intent of the statute, which is typically used to challenge unfair trade practices rather than establish a comprehensive global tariff regime. Peter Harrell, a Georgetown University law scholar, noted that Section 301 was not designed to enable the president to rewrite the U.S. tariff schedule on a sweeping basis. This concern is echoed by the Liberty Justice Center, which acted swiftly to file a lawsuit hours after the tariffs took effect, arguing that the administration is trying to resurrect a tariff regime the Supreme Court has already ruled unauthorized.

The legal challenges highlight the tension between the administration's stated goal of combating forced labor internationally and the underlying trade policy ambitions. While the administration insists the tariffs truly address forced labor, critics argue this is a pretext to maintain expansive tariff barriers on global imports. Scholars like Kimberly Clausing from UCLA highlight the lack of clear evidence that these tariffs effectively target forced labor issues, cautioning that the administration's approach could face prolonged court battles and uncertainty.

Despite opposition, some legal experts suggest the administration’s process in imposing the tariffs under Section 301 gives it some flexibility, potentially making these duties more resilient in court compared to the invalidated IEEPA tariffs. From a business standpoint, this means companies should prepare for the tariffs to remain in effect in the near term, as the process to modify or overturn them through litigation could be lengthy. Meanwhile, Trump has also announced forthcoming investigations into European Union trade practices and additional tariff measures targeting Brazil and Canada, signaling continued emphasis on trade enforcement.
