The U.S. will impose ⁠a 25% tariff on most imports from Brazil starting July 22, the U.S. Trade Representative's office said on Wednesday, the first action under the Trump administration's new tariff strategy that could eventually ​affect dozens of countries.

The new program, launched after the U.S. Supreme ​Court tore ⁠down the centerpiece of Trump's tariff system earlier this year, is based on investigations into unfair trade practices under Section 301 of the U.S. Trade Act.

Close to 80 trade investigations have been opened by the USTR office and a new wave of tariffs could be imposed on dozens of countries, including China, the EU, India, Japan, South Korea and Mexico.

Wednesday's announcement follows a proposal by the Trump administration in June to impose a punitive tariff of 25% on many imports from Brazil after deciding its practices were unfair on a range of issues from digital trade to illegal deforestation.

"Extensive negotiations with Brazil over the past year have not resolved these issues, but we remain open to continuing negotiations with Brazil to bring about long-needed ⁠changes ⁠to the problems identified in this investigation," U.S. Trade Representative Jamieson Greer said in a statement.

Brazilian President Luiz Inacio Lula da Silva said the U.S. decision was without any justification.

Brazil would immediately begin proceedings to invoke instruments provided for under the "Reciprocity Law" and revisit the matter within the framework of the WTO dispute settlement mechanism, he said on X.

U.S. Secretary of State Marco Rubio, who was accused by Lula of being anti-Latin America when the U.S. tariffs were proposed in June, blamed the Brazilian president and said, "Lula and his government have not negotiated with the U.S. in good faith."

"For the ⁠past year, Lula has put his own ego ahead of making a deal for the welfare of the Brazilian people, and these tariffs are the price for that," Rubio said in a strongly worded post on X.

The tariffs would apply to thousands of Brazilian imports, including sugar, agricultural machinery, apparel, electrical machinery, paper and steel.

The ​U.S. said it would exempt all the products proposed for exemption in the June notice, except high-purity dissolving pulp and non-pharmaceutical applications of certain products.

The exemptions include beef, coffee, rare ⁠earths, energy products, aircraft ‌and aircraft ‌parts.

The U.S. also added organic honey, pig iron, unflavored instant coffee and ⁠some other products to the list of exemptions on Wednesday.

The investigation ‌into Brazil, opened last July, cited several alleged unfair practices, including illegal deforestation and Brazil's instant payment system, Pix, which the U.S. ​government argues disadvantages credit card companies.

Brazil ⁠vehemently rejected all the allegations.

Brazil has also been included in a separate ⁠Section 301 investigation by the USTR, due to conclude on July 24, into connections to forced labor in ⁠the supply chains of ​dozens of countries.

The probe is expected to result in an additional 12.5% tariff, bringing the total burden for Brazilian products to 37.5%.
