Korean Oil Pipes Cleared in US Antidumping Check
Published Date: 3/16/2026
Notice
Summary
The U.S. Department of Commerce checked if certain oil pipes from South Korea were sold too cheaply in the U.S. during Sept 2023 to Aug 2024 and found they were not. This means no extra taxes (antidumping duties) will be added for now. Companies involved should keep an eye out because the review is still open for comments and final decisions are coming soon.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 3 costs, 1 mixed.
Preliminary Rates Set for Other Korean Firms
Commerce preliminarily assigned specific review-specific weighted-average dumping margins for non-examined Korean producers and exporters, including 1.18% for many firms (e.g., AJU Besteel, Dong-A Steel), 0.77% for HiSteel, and 11.70% for Kumkang Kind Co., Ltd., covering the September 1, 2023 to August 31, 2024 period. These preliminary rates will be used for assessment calculations unless changed in the final results.
Two Korean Exporters: No Preliminary Duties
Commerce preliminarily found that NEXTEEL Co., Ltd. and SeAH Steel Corporation had weighted-average dumping margins of 0.00% for the period September 1, 2023 through August 31, 2024. That means, for now, no antidumping duties will be assessed on entries attributable to those two companies while the review remains preliminary.
How Final Assessments Will Be Calculated
If, in the final results, an individually examined respondent's weighted-average dumping margin is at or above 0.50%, Commerce will calculate importer-specific ad valorem duty assessment rates and instruct U.S. Customs and Border Protection to assess those duties. If the final margin for an examined respondent is zero or de minimis (below 0.50%), Commerce will instruct CBP to liquidate the appropriate entries without regard to antidumping duties.
Cash Deposit Rules After Final Results
After publication of the final results, cash deposit requirements for shipments entered or withdrawn for consumption on or after that publication date will follow the final rates: company-specific final rates, but if a rate is less than 0.50% it will be treated as zero; and the all-others rate will remain 5.24%. These cash deposit requirements remain in effect until further notice.
Importer Certificate Requirement — Risk of Double Duties
Importers must file a certificate regarding reimbursement of antidumping duties prior to liquidation of the relevant entries for the September 1, 2023 through August 31, 2024 period. If an importer does not file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
