Detroit’s automakers have appealed to the Biden administration for protection from impending tariffs, following a Supreme Court decision that has cleared the path for President Donald Trump to reimpose broad trade duties. The American Automotive Policy Council (AAPC), representing General Motors, Ford, and Stellantis, sent a letter to Trump’s trade team Friday requesting the preservation of a framework shielding them from multiple import taxes on vehicles, and parts.
The automakers’ plea comes as they brace for potentially billions of dollars in additional costs stemming from Trump’s tariffs on imported autos and auto components, as well as duties on steel and aluminum. These tariffs were originally implemented under the premise of national security concerns, granting the president authority to impose import taxes. While the Supreme Court recently invalidated Trump’s broader import taxes levied against many countries, the automotive tariffs remained unaffected by that ruling.
Last April, President Trump signed directives designed to mitigate the impact of his tariffs on the automotive sector, specifically preventing the stacking of multiple levies on the same goods. The AAPC is now seeking to ensure this framework remains in place. According to a source familiar with the communication, the White House has yet to respond to the letter, which was first reported by the Wall Street Journal.
The urgency of the automakers’ request is underscored by Trump’s recent announcement Friday that he intends to impose a flat 10% levy on all foreign goods in the coming days. He similarly signaled plans to initiate a series of trade investigations that could pave the way for more permanent tariff measures. This stance contrasts with a July 2025 statement from Commerce Secretary Howard Lutnick, who claimed U.S. Auto CEOs were “cool with” a trade deal that imposed a 15% tariff on cars exported to the U.S. From Japan, despite the potential for disadvantaging domestic manufacturers compared to those operating in Canada and Mexico.
The AAPC, which represents Ford Motor Company, General Motors Company, and Stellantis, has previously expressed concerns about trade policies that could create uneven playing fields. In March 2025, the organization applauded a one-month tariff exemption granted by the Trump administration, recognizing the importance of exempting vehicles and parts meeting high US and regional USMCA content requirements. At that time, shares of Ford, General Motors, and Stellantis all experienced significant gains following the announcement.
The current situation presents a renewed challenge for the automotive industry, which relies heavily on complex, integrated supply chains spanning North America and beyond. The AAPC has stated its willingness to collaborate with the Trump administration to achieve shared goals of increasing U.S. Automotive production and expanding exports, but the imposition of broad new tariffs threatens to disrupt those efforts.
