By Brazil Stock Guide – The US Department of Commerce has upheld an antidumping tariff on aluminum products made by Companhia Brasileira de Alumínio (CBAV3.SA), keeping in place a measure first imposed in 2021. According to Broadcast, a real-time news service of Grupo Estado, the latest review concluded that between 2022 and 2023 the company sold aluminum sheets at prices 18.74% below the “fair value” defined by US trade regulators.
The tariff applies to aluminum sheets with a thickness of 0.2 millimeters or less. Analysts consulted by Broadcast noted that such administrative reviews rarely lead to meaningful changes once duties are in force, underscoring the likelihood that the CBA measures will remain.
Limited impact on CBA’s business
Despite the continuation of the tariff, the impact on CBA’s financial performance is expected to be modest. Company data released in March 2024 showed that 88% of its revenue comes from domestic sales. Roughly 10% of its production is exported, with only 3% of that volume shipped to the United States.
The company did not comment on the Commerce Department’s decision.
Tariffs imposed in 2021 and the current outlook
The antidumping duties on Brazilian aluminum sheets were imposed in November 2021 after the Department of Commerce completed its investigation and the US International Trade Commission confirmed injury to the domestic industry. The same measure also targeted exporters from Armenia, Oman, Russia and Turkey.
Since then, the duties have gone through annual reviews. In June 2024, the Commerce Department released its final results for the 2021–2022 administrative review, maintaining the finding of below-value sales. In December 2024, preliminary results for the 2022–2023 period reached the same conclusion, ensuring continuity of the tariffs.
As of 2025, President Donald Trump’s administration has kept the measures in place, reaffirming the use of antidumping tools to shield US industries deemed strategic.
