In a petition filed on July 14, 2011, three firms with production in the United States (the Sweden-based ABB, Inc., as well as Delta Star, Inc. and Pennsylvania Transformer Technology, Inc.) charged that large power transformers imported from Korea are being dumped. This same product had been subject to AD orders during 1972-2000 when imported from France, Italy, and Japan.
The petitioners allege an average dumping margin of 60.2%. The public version of the petition does not indicate the total value of the imports that are at issue.
The first stage in the investigation was the U.S. International Trade Commission's preliminary injury determination. The commission determined on August 26, 2011 that there is a reasonable indication that a U.S. industry is materially injured by reason of these imports. In its preliminary dumping determination the U.S. Department of Commerce found rates of 21.79-38.07% ( In its final determination ( published on July 11, 2012 the department found rates ranging between 14.95% and 29.04%. Orders were issued in that amount.

On September 12, 2018 the U.S. International Trade Commission determined that revoking the existing antidumping duty order on imports of large power transformers from Korea would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time. As a result of the Commission’s affirmative determination, the existing antidumping duty order on imports of this product from Korea will remain in place.
