The main purpose of the "No Tariffs on Groceries Act of 2025" is to restrict the President's ability to impose tariffs or duties on food items. This legislation aims to protect consumers from potential price increases on food products that could result from such tariffs. Key provisions of the Act include a requirement that the President must request Congress's approval before imposing any new duties or tariffs on food articles. This request must be accompanied by a specific joint resolution that Congress must enact to allow the imposition of the duty.
