In a notification, the Directorate General of Anti-Dumping and Allied Duties (DGAD) had said it has found prima facie evidence of dumping of aluminium from China.
"The authority hereby initiates an investigation into the alleged dumping, and consequent injury to the domestic industry... To determine the existence, degree and effect of any alleged dumping and to recommend the amount of anti-dumping duty, which if levied would be adequate to remove the injury to the domestic industry," the notification said.
The period of investigation is from April 2014 to March 2015.
