The official said investigations have been launched by the DGTR in response to dumping complaints filed by domestic producers including The Tinplate Company India Limited, a Tata Steel group company, and Vallabh Tinplate India Limited, and after the DGTR found prima facie evidence of dumping needing detailed investigations. While these two companies account for the bulk of domestic production of the products under investigations, state-run Steel Authority of India Limited (SAIL) also produced some volumes but has not joined the petitioners in lodging complaints of dumping, the official added. The DGTR has established a causal link between the alleged dumping and injury to domestic industry and has commenced investigations, the official said, quoting from the notification. The period between January 1, 2018 and December 31, 2018 will be taken into consideration for investigations and all stakeholders have been directed to submit their respective views and relevant information to the DGTR, the official added.
