CIT sustains Commerce scope ruling that IPG heat sinks fall within aluminum extrusions orders
The U.S. Court of International Trade, in Slip Op. 26-117, Court No. 25-00212, denied IPG Photonics Corporation's motion for judgment on the agency record and sustained Commerce's final scope ruling that IPG's four heat sink models do not meet the finished heat sink exclusion and are covered by the antidumping and countervailing duty orders on aluminum extrusions from China, Case Nos. A-570-967 and C-570-968. The court held that Commerce's interpretation of the exclusion and its consideration of IPG's evidence were supported by substantial evidence and in accordance with law. The opinion is dated September 23, 2026.
