Brazil has turned to Baker McKenzie—the largest American law firm—to mount a legal defense as the United States Trade Representative (USTR) officially investigates Brazil’s trading practices.
The probe, which launched on July 15, 2025 under Section 301 of U.S. trade law, allows Washington to take swift action if it believes another country’s regulations unfairly block American products or services.
At stake are Brazilian policies covering digital trade, payments, intellectual property, ethanol, customs, and environmental controls. If U.S. officials rule against Brazil, retaliatory tariffs could reach 50% or more on Brazilian exports.
That would hit Brazilian jobs and revenues while raising prices and disrupting supply for American businesses and consumers. Earlier Section 301 actions, especially targeting China, have led to escalating tariffs and long-lasting trade disputes.
Brazil’s Foreign Ministry secured Baker McKenzie’s services through an official contract worth $275,000, extended through January 2026, with payment only for services delivered. Brazilian procurement rules govern the contract.


Baker McKenzie, with over 4,000 lawyers spread across 70 global offices, typically earns its revenue from multinational companies and governments.
Baker McKenzie Leads Brazil’s Legal Fight on Global Trade Front
For over a decade, legal industry records have named Baker McKenzie as the nation’s largest law firm by number of attorneys.
Baker McKenzie brings deep courtroom and negotiation experience from representing both governments and major corporations—such as Apple—before the World Trade Organization and in high-stakes intellectual property cases.
The firm’s client roster crosses political lines, and public filings confirm individual lawyers often donate to the U.S. Democratic Party, but the firm itself stays strictly nonpartisan.
The Brazilian government’s choice shows a clear intent to challenge any new trade barriers using top-tier American legal expertise.
As both countries prepare for public hearings and evidence gathering, the case not only tests Brazil’s resolve but will also shape the rules of global commerce for businesses around the world.
