President Donald Trump signed an executive order Wednesday to impose his threatened 50% tariffs on Brazil, setting a legal rationale that Brazil’s policies and criminal prosecution of former President Jair Bolsonaro constitute an economic emergency under a 1977 law.

Trump had threatened the tariffs July 9 in a letter to President Luiz Inacio Lula da Silva. But the legal basis of that threat was an earlier executive order premised on trade imbalances being a threat to the U.S. economy. But America ran a $6.8 billion trade surplus last year with Brazil, according to the U.S. Census Bureau.

A statement by the White House said Brazil’s judiciary had tried to coerce social media companies and block their users, though it did not name the companies involved, X and Rumble.

Trump appears to identify with Bolsonaro, who attempted to overturn the results of his 2022 loss to Lula. Similarly, Trump was indicted in 2023 for his efforts to overturn the results of the 2020 U.S. presidential election.

Lula left an event about animal rights early on Wednesday after Trump’s move, saying he needed to defend “the sovereignty of the Brazilian people in light of the measures announced by the President of the United States.”

The order would apply an additional 40% tariff on the baseline 10% tariff already being levied by Trump. But not all goods imported from Brazil would face the 40% tariff: Civil aircraft and parts, aluminum, tin, wood pulp, energy products and fertilizers are among the products being excluded.

The order said the tariffs would go into effect seven days after its signing on Wednesday.

Also Wednesday, Trump’s Treasury Department announced sanctions on Brazilian Supreme Court Justice Alexandre de Moraes over alleged suppression of freedom of expression and Bolsonaro’s ongoing trial.

De Moraes oversees the criminal case against Bolsonaro, who is accused of masterminding a plot to stay in power despite his 2022 defeat.

On July 18, the State Department announced visa restrictions on Brazilian judicial officials, including de Moraes.
