Brasilia didn’t wait long. On August 13, the Brazilian government formally opened a process that could trigger reciprocal measures against the United States. The move responds directly to 25% tariffs Washington slapped on select Brazilian goods last month. Officials called those duties unjustified and arbitrary.
Brazil’s Reciprocity Law Gains New Teeth
The process begins with a request for further diplomatic consultations. Yet it carries real weight. Brazil’s Reciprocity Law, passed unanimously by Congress, equips the government to go beyond simple import duties. It opens the door to countermeasures that hit American companies where they earn steady profits.
President Luiz Inacio Lula da Silva made the threat clear back in July. When the Trump administration announced the tariffs, he promised immediate steps to activate the law. “The U.S. tariffs are unjustified and arbitrary, and Brazil will continue to defend its position in all appropriate forums,” the government stated Thursday, according to Reuters.
Those words carry history. Relations have soured. Diplomatic spats, including the U.S. revocation of a visa for Brazil’s ambassador, have added fuel. But the core dispute sits in trade numbers and policy choices. The U.S. cited unfair practices. Brazil sees protectionism.
The July tariffs stemmed from a Section 301 investigation. U.S. Trade Representative Jamieson Greer pointed to issues ranging from digital trade barriers and ethanol market access to illegal deforestation. Tariffs took effect July 22. A separate 12.5% levy tied to forced labor concerns hit Brazil alongside dozens of other nations. Brazil rejected both as pretexts.
And the numbers matter. The U.S. runs a trade surplus with Brazil. It doubled to $14.4 billion in 2025. Yet two-thirds of Brazilian exports to the U.S. escaped the new duties thanks to exemptions. Those carve-outs, analysts say, expose the limits of broad tariff threats. They also highlight how intertwined the economies remain. Coffee, beef, aircraft parts. Many dodged the hit.
Brazil has options. In July, government sources told Reuters it was reviewing curbs on U.S. audiovisual companies and suspension of pharmaceutical and agricultural patents. Such steps avoid direct import taxes that could spike Brazilian consumer prices or snarl supply chains. They target revenue streams instead. Dividend and royalty remittances. Intellectual property protections in key sectors.
Those sectors matter. Agriculture seeds. Pharmaceuticals. Technology. American firms generate some of their most reliable Brazilian income there. Suspending IP obligations could sting. The Peterson Institute for International Economics laid it out plainly. “The Economic Reciprocity Law’s most potent instrument is the suspension of intellectual property obligations affecting sectors such as agriculture (seeds), pharmaceuticals, and technology—sectors where US companies earn their most reliable income from Brazil,” wrote senior fellow Monica de Bolle in a July 17 analysis for the Peterson Institute for International Economics.
De Bolle went further. She argued the U.S. demands during negotiations violated Brazil’s own trade laws and Mercosur commitments. Exclusive concessions to one partner? Not feasible. Negotiations collapsed. Tariffs followed. Exemptions came later in some cases, recalling earlier 2025 duties that courts later struck down.
So the strategy shows cracks. Brazil diversifies. China takes 37% of its exports now. Trade with India jumped over 50% recently. Tariffs, de Bolle noted, may simply accelerate that shift. Facilitate trade diversion. “One can only conclude that those responsible for putting egos ahead of making deals are not the people sitting in Brasília, but those based in Washington,” she wrote.
Brazil plans to revive a World Trade Organization dispute as well. It filed consultations earlier. The reciprocity process runs parallel. Lula’s team has signaled openness to talks. But it won’t accept unilateral pressure. Support measures for affected Brazilian exporters are expected by August’s end.
The stakes stretch beyond bilateral flows. Mercosur obligations constrain Brazil. It cannot easily grant one country what it denies others. That legal reality frustrated U.S. negotiators. It also arms Brazil’s defense. Retaliation, when it comes, will likely stay within those bounds. Targeted. Legal. Costly for specific U.S. industries.
Reactions in markets have been measured so far. Brazilian stocks dipped on the news but recovered quickly. Commodity traders watch soy, iron ore, coffee. Supply chains that cross the equator multiple times each year. A full-blown tariff war would raise costs everywhere. Inflation risks in Brazil. Higher input prices in the U.S.
Yet neither side seems eager for that outcome. Brazil notified the U.S. of the process and requested consultations. Diplomacy first. But the clock ticks. If talks stall, the reciprocity measures gain momentum.
Earlier this year the White House adjusted its Brazil tariff scope. It exempted more agricultural goods to ease domestic food prices and reflect negotiation progress. Those moves showed flexibility. They also revealed the tariffs’ original breadth exceeded practical limits. Courts. Allies. Domestic lobbies. All push back.
Now the ball sits in both courts. Brazil’s move formalizes its response. It buys time for analysis. Camex, the foreign trade board, will study impacts. Recommendations will flow to Lula. He decides. Sources close to the process say a tough reply remains likely unless concessions emerge.
This isn’t new territory. Trade spats between the two have flared before. But the current tools differ. The Reciprocity Law, approved in 2025, gives Brasilia novel leverage. IP suspension. Investment curbs. Services restrictions. Measures that bite without broad consumer pain.
U.S. officials have warned of further reviews if Brazil acts. The cycle risks escalation. And yet both economies need each other. American firms value Brazil’s market. Brazilian producers rely on U.S. demand for premium goods. Disruptions hurt both.
Observers point to the forced labor angle as particularly contentious. Brazil denies lax enforcement. It calls the tariff politically motivated. The link to broader Trump administration trade policy seems clear. Reciprocal tariffs. Section 301 revivals. Pressure on multiple fronts. China. India. Now deeper into Latin America.
Brazil’s October elections add another layer. Domestic politics could harden positions. Lula’s base favors strong defense of sovereignty. Opposition may criticize any perceived weakness. The reciprocity process gives the government a visible tool. It signals action.
Longer term, the dispute tests the WTO system. Both sides plan to use its mechanisms. Dispute settlement remains slow. Results uncertain. Yet it provides a rules-based venue. Better than unilateral action alone.
The August 13 announcement changes little immediately. Consultations begin. Analysis deepens. Markets price in uncertainty. But it marks a formal shift. From threat to structured process. From statements to potential implementation.
Brazil holds cards. Its market size. Commodity power. Diversified partners. The U.S. holds others. Technology edge. Investment flows. Consumer market. How each plays them will shape the outcome. For now, the reciprocity process unfolds. Watch the patent dossiers. The remittance rules. The quiet negotiations behind closed doors.
Because this fight won’t stay quiet for long. Global supply chains feel every tariff. Companies adjust. Governments respond. And the two largest economies in the Americas edge toward a new, uneasy balance.
