In a landmark decision with profound implications for global trade, the US Supreme Court has invalidated former President Donald Trump’s authority to impose sweeping global tariffs under the International Emergency Economic Powers Act (IEEPA). The ruling has ignited a complex mixture of relief and apprehension within the American business community, particularly among import-dependent industries that have borne the brunt of these trade policies.
Jenelle Peterson, co-founder of Canadian toy manufacturer Wild Life Outdoor Adventures, exemplifies this cautious optimism. Her company, which produces goods in China, suffered a 25% profit reduction last year due to Trump’s tariffs. While contemplating increased imports and new product designs previously put on hold, Peterson remains wary about potential administrative workarounds. “I have a bit of reservation in too much celebration,” she acknowledged. “But for us, every percentage point matters.”
The court’s decision specifically targets tariffs implemented under the 1977 IEEPA statute, but leaves untouched other tariff authorities that the Trump administration could leverage. Within hours of the ruling, Trump announced plans to sign an executive order imposing a 10% global tariff under a separate statute allowing temporary import taxes of up to 15% for 150 days. “We have other ways – numerous other ways,” Trump declared at a White House briefing, anticipating prolonged legal battles.
Business reactions reflected this uncertainty. Rick Woldenberg, CEO of educational toy maker Learning Resources (which challenged the tariff policy), called the ruling a “major victory” while expressing skepticism about proposed alternatives: “If the government is bound and determined to try to harm us through excessive taxes, I’m sure they’ll find a way.”
Despite the judicial setback, protectionist measures remain substantial. Yale University’s Budget Lab calculates that even without IEEPA tariffs, consumers and businesses face an average effective tariff rate of 9.1%—the highest since 1946 excluding 2025. John Arensmeyer of Small Business Majority noted that while ending most tariffs “will undoubtedly benefit Main Street,” they have already caused “significant and irreparable harm to many small businesses.”
Financial markets responded favorably but moderately to the news. The S&P 500 rose 0.7% and the Nasdaq gained 0.9%, though analysts cautioned against expecting sustained reactions. Lauren Goodwin of New York Life Investments observed that “sector winners and losers from this news depend on whether and how rebates are processed, as well as the use of non-IEEPA tariffs from here.”
The ruling’s practical impact extends to consumer pricing. Peterson maintained stable prices for six months after Trump’s return to office before ultimately raising a knot-tying game from $14.99 to $19.99. She hopes the decision might eventually allow price reductions, praising the Court for sending “a really good message that we can’t have these insane fluctuations in tariff rates and economic policy, because it’s so damaging to small businesses.”
Trade associations representing larger companies welcomed the clarity while emphasizing the importance of seamless refund processes. David French of the National Retail Federation stated the decision “provides much-needed certainty for US businesses and manufacturers, enabling global supply chains to operate without ambiguity.”
Economic analyses consistently demonstrate that US consumers and businesses primarily absorb tariff costs rather than foreign exporters. Michael Pearce of Oxford Economics warned that even if the administration replicates overall tariff levels through alternative means, “the by-sector and by-country implications could end up looking quite different, which will create another bout of trade policy uncertainty for businesses, investors, and households.”
