U.S. Launches Broad Trade Probe Into Brazil, Targeting Tariffs, Tech, and Environmental Policy

The United States government has launched a major trade investigation targeting Brazil, deepening economic and political tensions between the two largest countries in the Americas.

The move, ordered by President Donald Trump, follows his recent threat to impose a steep 50 percent tariff on imports from Brazil, a penalty scheduled to take effect August 1 — a move Brazilian officials are scrambling to avert.

What Is the Investigation About?

The Office of the United States Trade Representative (USTR) initiated the formal probe under Section 301 of the Trade Act of 1974 on July 15, 2025.

This rarely used but powerful U.S. law allows for retaliatory action against what the U.S. sees as unfair or discriminatory foreign trade practices. The USTR’s investigation is unusually broad. It will examine whether Brazilian government policies:

Discriminate against American tech firms

Citing alleged “attacks” on U.S. social media and digital service providers, potentially for not censoring political speech as Brazil’s government requests.

Impose unfair tariffs, especially on ethanol

U.S. ethanol exports to Brazil fell from a high of $761 million in 2018 to just $53 million in 2024, after Brazil imposed a series of escalating tariffs — reaching 18 percent by late 2024. This reversed a decade of largely tariff-free trade.

Favor rival exporters 

Preferential tariff policies toward other countries allegedly give U.S. competitors better market access, disadvantaging American products.

Fail at fighting corruption

Weak enforcement of anti-corruption laws allegedly creates unfair advantages for local and non-U.S. companies operating in Brazil.

Undermine intellectual property protection

Insufficient enforcement of IP rights may harm U.S. companies relying on innovation and creativity.

Allow illegal deforestation

Allegedly lax environmental enforcement enables widespread illegal logging and deforestation in the Amazon. In 2024, deforestation in Brazil reached an estimated 3,400 hectares per day, with as much as 91 percent of it classified as illegal.

The U.S. argues these practices reduce production costs for Brazilian exporters of agricultural and timber goods, harming American producers.

The Political Backdrop

The probe comes less than a week after Trump’s administration announced the 50 percent tariff hike — a measure believed to be driven in part by political considerations.

The move followed Trump’s public defense of Brazil’s former president Jair Bolsonaro, who is currently on trial for allegedly attempting to overturn Brazil’s 2022 election.

Calling the trial a “disgrace,” Trump sent a strongly worded letter to Brazilian officials calling for Bolsonaro’s acquittal.

President Luiz Inácio Lula da Silva has responded sharply, denouncing the tariff threats as “irresponsible” and accusing Washington of trying to interfere in Brazil’s sovereign legal affairs.

The dispute has cast a deep chill over U.S.-Brazil relations, which had recently shown signs of closer coordination under bilateral environmental and trade talks.

What Happens Next

• The USTR is accepting public comments until August 18 and will hold a hearing on September 3, 2025.
• The investigation could lead to formal U.S. trade sanctions or pressure on Brazil to make policy changes.
• The two countries, once strategic partners in hemispheric trade and climate diplomacy, are now at odds over both economic practices and democratic norms.

This confrontation goes far beyond tariffs. It is a deepening clash over governance, markets, and influence — one that could reshape economic alignments across Latin America and beyond.
