Lula Reacts to Trump’s Tariff: Brazil Threatens Retaliation with Tariffs, Restrictions on Investments, and Even Intellectual Property under New Reciprocity Law
The Economic Reciprocity Law has emerged as Brazil’s main response to the 50% tariff imposed by Donald Trump on national exports.
Sanctioned in April and already invoked by President Luiz Inácio Lula da Silva, the measure authorizes Brazil to take countermeasures far beyond product taxation, directly affecting investments and even the intellectual property of U.S. companies.
According to information from O Globo, the decision was communicated by the Itamaraty to the Foreign Trade Chamber (Camex), which will have up to 30 days to define the first steps of retaliation.

China is about to get its hands on one of Brazil’s largest nickel sources, but the European Union has decided to hold up the $500 million deal and may even block the sale permanently in the coming months.
The message is clear: Brasília does not intend to passively accept Washington’s unilateral measures.
What the Economic Reciprocity Law Allows
The Economic Reciprocity Law is unprecedented in the Brazilian legal framework.
It provides that, in the face of trade barriers imposed against the country, the government may respond proportionally, including with suspension of trade concessions, patent blocking, and restrictions on foreign investments.
This means that American companies in the technology, pharmaceutical, and financial sectors could be directly impacted if the U.S. does not back down.
For analysts, this possibility changes the dynamics of trade disputes, as it targets strategic areas of the American economy.
Behind the Scenes of Lula’s Decision
Sources involved with the Planalto say that Lula decided to invoke the law after realizing that ministers such as Geraldo Alckmin (Industry and Trade), Fernando Haddad (Finance), and Mauro Vieira (Foreign Affairs) were not even consulted by Washington before the imposition of tariffs.
At the same time, Brazil opened a formal dispute at the World Trade Organization (WTO) and hired a law firm in the U.S. to bolster its defense on American soil.
The strategy, according to insiders, combines international legal pressure with a firm political message.
Impacts and Risks of Retaliation
If the law is fully applied, Brazil could impact the intellectual property of American multinationals, something unprecedented in the history of bilateral relations.
Moreover, direct investments from large companies may face regulatory restrictions.
For experts, this stance could increase Brazil’s bargaining power in future negotiations but also carries risks of escalation in the conflict.
If no agreement is reached, the impasse could turn into a trade war, with bilateral repercussions and within the WTO.
The Economic Reciprocity Law places Brazil on a new level of diplomatic confrontation, offering tools that were not previously available.
The measure signals that Brasília does not intend to accept unilaterally imposed tariffs without reaction.
And what do you think, should Brazil use the law to the fullest, including blocking patents and restricting American investments, or would you prefer a negotiated solution to avoid a larger conflict? Share your opinion in the comments — we want to hear from those who live this firsthand.
