The White House is reconstructing its tariff program through multiple trade laws after the Supreme Court invalidated the previous approach, senior adviser Peter Navarro said.
The White House is rebuilding its tariff regime through at least three separate trade-law investigations after the Supreme Court struck down the prior program, senior adviser Peter Navarro said Thursday, opening new fronts on forced labor, EU technology policies and foreign industrial overcapacity.
"These investigations give us the legal foundation to protect American workers and industries using statutes Congress has long provided," Navarro said in an interview. "The Supreme Court closed one door, but Congress left several others open."
The new approach relies on trade laws targeting forced labor in global supply chains, Section 301 authorities addressing the European Union's treatment of US technology companies and separate probes into foreign industrial overcapacity. Specific tariff rates, affected trade volumes and effective dates have not yet been disclosed.
The reconstruction effort threatens to escalate trade conflicts across multiple fronts simultaneously. New duties on EU tech companies could affect billions of dollars in transatlantic digital services trade, while overcapacity investigations may target sectors from steel to semiconductors — raising costs for multinational corporations and potentially reigniting inflation pressures.
The Supreme Court's decision earlier this year invalidated the administration's previous tariff framework, which had relied on a broad interpretation of executive authority under the International Emergency Economic Powers Act. The ruling forced the White House to return to statutory trade laws that require formal investigations, public comment periods and specific findings of injury or unfair practices. The previous tariff regime had covered roughly $380 billion in annual US imports before the court struck it down, according to Census Bureau data.
The forced-labor component targets supply chains where US Customs and Border Protection has identified potential violations. The administration is expected to issue withhold-release orders on specific products, though Navarro did not specify which goods or countries would be affected first. Similar forced-labor authorities have previously been applied to products from Xinjiang cotton to electronics components, affecting an estimated $5 billion in annual trade.
EU Tech Probe Targets Digital Services
The investigation into the European Union's treatment of US technology companies marks a significant escalation in transatlantic trade tensions. The EU has imposed digital services taxes on American firms including Apple Inc., Alphabet Inc.'s Google and Meta Platforms Inc., drawing threats of retaliatory tariffs from Washington for years. The Section 301 probe — the same statute used during the US-China trade war that imposed tariffs on $370 billion in Chinese goods — could lead to duties on European digital services, luxury goods or agricultural products. The US trade deficit in digital services with the EU stood at roughly $18 billion in 2025, according to Bureau of Economic Analysis data.
Overcapacity Investigations Broaden Scope
Separate probes into foreign industrial overcapacity could affect multiple sectors where global supply exceeds demand. The administration is examining whether state-subsidized production in countries such as China has depressed prices and harmed US manufacturers. Previous overcapacity actions have targeted steel and aluminum, where US tariffs of 25% have been in place since 2018, but the new investigations may extend to semiconductors, solar panels and electric vehicles. The previous US tariff on Chinese EVs added roughly $12,000 to the sticker price of a $48,000 vehicle, according to industry estimates.
For investors, the multi-front tariff strategy introduces uncertainty across supply chains, corporate margins and inflation expectations. Companies with exposure to EU digital services, Asian manufacturing and cross-border supply chains face the highest risk of cost increases. The next milestone will be the publication of formal investigation findings, which will trigger specific tariff proposals and public comment periods.
