The Brazilian government presented a request for consultations to the World Trade Organization (WTO) dispute settlement system on Monday night, October 27, targeting a series of new tariffs implemented by the administration of Donald Trump, according to the Ministry of Foreign Affairs.
The formal trade action responds to two separate measures enacted by Washington over recent weeks. According to an official statement from the Itamaraty, Brazil considers the American measures unjustified and incompatible with U.S. obligations under the General Agreement on Tariffs and Trade of 1994 (GATT 1994) and the WTO Understanding on Rules and Procedures Governing the Settlement of Disputes.
Timeline of U.S. Tariffs and Trade Investigation
On October 22, the United States applied a 25% tariff against specific Brazilian products. This move stemmed from an investigation that developed after Trump announced an initial 50% tariff against Brazil in July 2025. Earlier in June, the United States Trade Representative (USTR) proposed imposing this specific rate under Section 301 of the U.S. Trade Act, a trade policy tool that permits the U.S. to investigate and retaliate against other nations over commercial practices deemed unfair.
Despite public hearings where civil society voiced opposition to the tariff plan, the USTR determined that Brazilian government policies regarding digital commerce, preferential tariffs, anti-corruption efforts, patent processing and piracy, ethanol, and illegal deforestation create legal uncertainty and unfair competition for U.S. players.
Did You Know? The current WTO challenge follows an investigation that began after an initial 50% tariff was announced against Brazil in July 2025, eventually leading to a 25% tariff enacted on October 22 alongside a separate 12,5% duty on October 24.
Second Measure Targets Forced Labor Regulations
A second trade measure took effect on October 24, introducing a 12,5% tariff applied against countries deemed to have failed in adopting and enforcing prohibitions on importing products derived from forced labor, as stated by the USTR. Government calculations indicate that for certain products, these two distinct tariffs combine to create an aggregate rate of 37,5%. This cumulative rate applies to 16,5% of the total Brazilian export agenda directed to the United States.
