The United States International Trade Commission issued the final judgment on the third anti-dumping sunset review of industrial damage of magnesium metal.

On October 28, 2021, the United States International Trade Commission ((ITC)) voted to make the third anti-dumping review on magnesium imports from China. The sunset review of the final determination of industrial damage, USITC ruled that the lifting of the current anti-dumping duty on magnesium imports from China may lead to the continuation or recurrence of material damage within a reasonably foreseeable period of time. According to the final verdict, the current anti-dumping measures in this case continue to be effective. In the ruling, Chairman Jason E. Kearns, Vice Chairman Randolph J. Stayin and members David S. Johanson, Rhonda K. Schmidtlein and Amy A. Karpel voted in favour.
