Commerce Slaps Duties on Korean Welded Pipes for Unfair Pricing
Published Date: 5/1/2026
Notice
Summary
The U.S. Department of Commerce found that SeAH Steel from Korea sold large diameter welded pipes in the U.S. at unfairly low prices from May 2023 to April 2024, while Hyundai Steel Pipe did not. Starting May 1, 2026, new duties will apply to SeAH’s pipes to level the playing field. This means importers might pay more, and Korean pipe makers will need to adjust their prices.
Analyzed Economic Effects
6 provisions identified: 1 benefits, 4 costs, 1 mixed.
Unknown-U.S.-Destination Entries May Face 7.08% Rate
For POR entries produced by HSP or SeAH where the producer did not know the merchandise was destined for the United States, Commerce will instruct CBP to liquidate those entries at the original all-others LTFV rate of 7.08 percent if there is no rate for the intermediate company(ies) involved.
Duties Applied to SeAH Imports
Commerce found SeAH Steel sold large diameter welded pipe in the U.S. at dumped prices for the period May 1, 2023 through April 30, 2024 and assigned SeAH a weighted-average dumping margin of 0.80 percent. As of May 1, 2026, antidumping duties tied to that 0.80 percent margin will apply to SeAH’s subject pipe entries.
No Duties for Hyundai Steel Pipe
Commerce determined Hyundai Steel Pipe Co., Ltd. (HSP) had a zero weighted-average dumping margin for May 1, 2023 through April 30, 2024. Commerce intends to instruct U.S. Customs and Border Protection to liquidate appropriate entries for HSP without regard to antidumping duties.
0.80% Rate for Listed Korean Exporters
Commerce assigned a review-specific dumping margin of 0.80 percent to the non-examined Korean producers/exporters listed in Appendix II (21 companies). Importers of pipe from those listed firms will face duties tied to that 0.80 percent rate.
Cash Deposit Rates Take Effect on Publication
For shipments entered or withdrawn for consumption on or after the publication date (May 1, 2026), cash deposit rates will equal the final review margins: HSP at 0.00 percent and SeAH at 0.80 percent. Other producers/exporters will continue to have either their most recently published company-specific rates or the all-others rate of 7.08 percent.
How and When Duties Will Be Assessed
Commerce will direct U.S. Customs and Border Protection to assess antidumping duties on appropriate entries using importer-specific ad valorem assessment rates calculated from dumping amounts and entered value, and will issue assessment instructions no earlier than 35 days after publication. Duties will be assessed only when the importer-specific rate is above the de minimis threshold of 0.50 percent.
