Oman Aluminum Faces Duty Slap: Fair Trade or Just Metal Mayhem?
Published Date: 4/16/2026
Notice
Summary
The U.S. Department of Commerce found that Oman Aluminium Rolling Company sold aluminum sheets in the U.S. at unfairly low prices from April 2023 to March 2024. Because of this, extra duties will apply to their imports starting April 16, 2026, helping U.S. aluminum makers compete fairly. This means companies importing from Oman should expect changes in costs and rules soon.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 6 costs, 0 mixed.
14.71% Antidumping Duty on Omani Sheet
If you import common alloy aluminum sheet produced or exported by Oman Aluminium Rolling Company SPC (OARC), a 14.71 percent antidumping duty applies based on Commerce’s final results for April 1, 2023 through March 31, 2024. This determination is applicable beginning April 16, 2026 and will increase the cost of those shipments.
Cash Deposit Rate Set at 14.71%
For shipments of the subject merchandise exported by OARC entered for consumption on or after the publication date, the cash deposit rate required at import will be equal to the 14.71 percent weighted-average dumping margin. These cash deposit requirements take effect on the date of publication of the final results and remain in effect until further notice.
File Reimbursement Certificate or Risk Double Duties
Importers must file a certificate about whether antidumping duties were reimbursed prior to liquidation of relevant entries. If you fail to file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
Automatic Assessment for Unreviewed Intermediary Shipments
Commerce will apply its automatic-assessment practice to entries produced by OARC where the producer did not know that merchandise it sold to an intermediary was destined for the United States; in those cases, CBP will be instructed to liquidate unreviewed entries at the all-others rate if there is no rate for the intermediary company.
All-Others Cash Deposit Rate Remains 5.29%
If you import common alloy aluminum sheet from producers or exporters not covered in this review, the cash deposit rate will continue to be 5.29 percent (the all-others rate). Company-specific rates for firms covered in prior completed segments continue to apply for those firms.
Timing of Duty Assessment and Liquidation Holds
Commerce will instruct U.S. Customs and Border Protection (CBP) to assess antidumping duties no earlier than 35 days after publication of the final results. If a timely summons is filed at the U.S. Court of International Trade, CBP will be instructed not to liquidate relevant entries until the time to request a statutory injunction has expired (within 90 days of publication).
