The U.S. Department of Commerce announced the results of a review about aluminum sheets coming from Taiwan. They found that a company sold aluminum sheets at prices lower than usual during 2023 and 2024.

Important Dates

The findings are effective from April 16, 2026.

Background

In August 2025, the Department asked for opinions on the matter. There were delays due to a government shutdown and technical issues. Because of these reasons, the final results were delayed until April 16, 2026.

Scope of the Review

The review looked at common alloy aluminum sheets from Taiwan to see if they were priced too low.

Findings

The review showed that C.S. Aluminium Corporation, a producer from Taiwan, had a dumping margin of 0.71 percent.

Next Steps

The Commerce Department will work with the U.S. Customs and Border Protection to apply duties on the aluminum sheets. These duties are based on how much the products were underpriced.

Cash Deposit Requirements

For future imports, a cash deposit based on these findings will be needed. If there is no specific rate for a company, a default rate of 17.50 percent will apply.

Notification to Importers

Importers need to follow rules about reimbursing antidumping duties to avoid penalties.

End Note

These results are official as of April 16, 2026, by the Department of Commerce, ensuring fair trade practices.
