U.S. Department of Commerce Finds No Antidumping in Large Diameter Welded Pipe from Korea
Estimated reading time: 3–5 minutes
On July 30, 2026, the U.S. Department of Commerce published the preliminary results of its review concerning large diameter welded pipe imported from the Republic of Korea. The review covers the period from May 1, 2024, through April 30, 2025. This review was administered by the International Trade Administration, a part of the Department of Commerce focusing on enforcing trade laws and agreements.
In its findings, the Department of Commerce established that the major producers and exporters of the pipe from Korea did not sell the merchandise at prices less than the normal value in the United States during the period under review. The reviewed companies, Hyundai Steel Pipe Co., Ltd. (HSP), and SeAH Steel Corporation, were examined separately, and both received results showing a zero percent dumping margin.
The Department’s methodology in such reviews involves examining whether products were sold at less than their fair value, which can be detrimental to local manufacturers. If dumping is discovered, additional duties could be imposed. However, since the dumping margin for the two companies was calculated to be zero, no duties for improper pricing will be collected against them.
The review process is detailed and includes many steps to ensure accuracy and fairness. Initially initiated on June 25, 2025, the review process experienced some delays due to the Federal Government’s shutdown around that time, but it eventually concluded with preliminary results.
Moreover, the Department of Commerce also mentioned rescinding the review concerning 15 companies because there were no suspended entries during the review period. When there are no shipments recorded, specific reviews can be terminated following the regulations of the Department of Commerce.
The current review also addresses the duty rates for non-individually examined companies. Since HSP and SeAH both received a zero percent margin, other companies not individually reviewed are assigned an earlier established duty rate of 0.80 percent from a previous period.
Public comments on the preliminary results of this review are welcomed until the completion of the process, with specific instructions provided to ensure they follow the review’s procedural regulations. Additionally, a verification process of the information used is intended before the final results are published.
Lastly, following the preliminary outcome, adjustments to cash deposits required by U.S. importers have been set to mirror the findings of this review, stipulating zero duties when no dumping margin is detected while maintaining existing duty levels where necessary. These results highlight compliance with U.S. antidumping policies by Korean manufacturers during the period reviewed.
