<h1>Reciprocal tariffs address foreign non tariff barriers, imposing responsive levies where market access is restricted to domestic firms.</h1> The administration declares a national emergency and implements reciprocal tariffs to counter foreign trade practices restricting US market access. It singles out non tariff barriers-including duplicative testing and certification for chemicals, telecom products, and medical devices-as impediments that make it costly for US firms to sell abroad, and cites tariff asymmetries and higher average MFN rates among trading partners as justification for responsive levies designed to strengthen US economic and national security.
