The US antidumping duty order on magnesium metal from Russia will officially be revoked April 15, following a sunset review vote from the US International Trade Commission in February, according to a Department of Commerce notice published in Thursday's Federal Register. April 15 is the fifth anniversary of the publication date of the antidumping duty order.

On March 1, 2010, Commerce and the ITC instituted the sunset review, which is required by trade law after five years to determine if the antidumping duty order is still needed to prevent dumping of the imports or injury to the US industry.

Despite the planned revocation, Commerce will complete the pending fifth administrative review of the Russian antidumping duty order for the period April 1, 2009, to March 31, 2010, because the period of review preceded the April 15 effective date of revocation, according to a source.

Commerce also published notice this week that it had extended the time to complete that review, which was originally expected to be finished by March 16. Commerce said it needed more time and extended the deadline for issuing preliminary results by 45 days to April 30. Any dumping margin found for shipments during that period would be applied retroactively to those imports.
