25 U.S. States File Suit to Block Trump’s July 24 Section 301 Tariffs

Washington’s tariff pendulum keeps swinging further from the post-1994 WTO consensus. The last time the United States tried across-the-board duties—the Smoot-Hawley Act of 1930—global trade shrank 66 % by 1934. Section 301 itself was a Reagan-era cudgel against Japan in the late-1980s and against China in 2018, but those were targeted; using it to tax nearly all imports revives a pre-GATT mentality and tests the constitutional line between Congress’s commerce power and an expansive presidency. The states’ revolt evokes the 1832 Nullification Crisis, hinting at sub-federal pushback when national trade policy hits local pocketbooks. Over a 100-year arc the episode signals a structural shift: the U.S. is normalising tariffs as a standing revenue/human-rights tool, eroding the rules-based system it once championed and inviting reciprocal barriers that could redraw supply chains and even the dollar-centric order.
