On the news front, the United States had previously planned to impose a 25% tariff on Auto Parts starting May 3. In response to the impending Auto Parts tariffs, the six major organizations representing the American automotive industry have unusually joined forces to lobby the Trump administration against imposing this tariff. In a letter to officials in the Trump administration, they stated that the impending tariffs could jeopardize American automotive production. The letter pointed out that many automotive suppliers are already in "trouble" and cannot bear additional cost increases, leading to broader industry issues.
