Taiwan's Cheap Sheets Get Pricier: U.S. Trade Shield Activated
Published Date: 4/16/2026
Notice
Summary
The U.S. Department of Commerce found that a Taiwanese company sold aluminum sheets in the U.S. at unfairly low prices from April 2023 to March 2024. Because of this, they’re setting new antidumping duties starting April 16, 2026, which means importers might pay more to keep things fair. This decision affects businesses importing aluminum sheets from Taiwan and helps protect U.S. manufacturers.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
All-Others Rate Remains 17.50%
For exporters or manufacturers not covered by a company-specific rate, Commerce will continue to apply the all-others cash deposit and assessment rate of 17.50 percent for common alloy aluminum sheet from Taiwan. Commerce will also instruct U.S. Customs and Border Protection to liquidate certain unreviewed entries at the all-others rate where appropriate.
Cash Deposit Rules Effective April 16, 2026
Starting on the publication date (April 16, 2026), importers must make cash deposits for shipments of aluminum sheet from Taiwan according to the rates set in these final results: the company-specific rate for reviewed companies, the manufacturer-specific rate where applicable, or the 17.50% all-others rate for other firms. These cash deposit requirements will remain in effect until further notice.
Reimbursement Certificate and Double Duty Risk
Importers must file a certificate about reimbursement of antidumping duties before liquidation for entries in this review, per 19 CFR 351.402(f). If importers fail to file the required certificate, Commerce may presume reimbursement occurred and could assess double antidumping duties.
Decision Aims to Protect U.S. Manufacturers
Commerce's final determination that sales were made at less-than-fair-value is intended to enforce antidumping duties to help protect U.S. manufacturers from unfairly priced imports of common alloy aluminum sheet from Taiwan. The review covers the period April 1, 2023 through March 31, 2024 and the notice is applicable April 16, 2026.
Duty Applied to C.S. Aluminium: 0.71%
Commerce found that C.S. Aluminium Corporation sold common alloy aluminum sheet in the U.S. below normal value for the period April 1, 2023 through March 31, 2024 and assigned a weighted-average dumping margin of 0.71 percent. Because 0.71% is above the de minimis threshold of 0.5 percent, antidumping duties will be assessed for entries covered by this review.
