TOPLINE: The Trump administration recently announced new tariff investigations on 16 countries and the European Union. If these investigations replicate the tariffs struck down by the Supreme Court, it will result in a $438 billion annual tax hike.
• U.S. consumers imported $2.6 trillion from those countries in 2025. • Investigations are intended to replace tariffs eliminated by the Supreme Court decision on International Emergency Economic Powers Act (IEEPA). • Average tariffs on those countries were 16.8% before SCOTUS’ IEEPA ruling. • Over ten years, these tariffs would result in a tax increase of $4.4 trillion.
