Federal courts have struck down key elements of President Trump’s reciprocal tariffs on numerous U.S. trading partners, citing the lack of valid legal emergency justification. The ruling disrupts tariffs that had generated hundreds of billions in tariff revenue and supported a series of trade deals with global partners like the EU and Japan. While some tariffs remain in place pending appeals, the decision threatens significant government income streams and complicates ongoing trade enforcement policies. Meanwhile, the expiration of the de minimis tariff exemption now subjects low-value overseas e-commerce imports to tariffs, impacting major retailers and shoppers observably.
