In the "event of revocation or cessation of anti-dumping duties, dumping of subject goods from subject country (China) and injury to domestic market is likely to continue or intensify," it had observed.
In case of mulberry raw silk, DGAD had stated "the material injury has been caused by the dumped imports of the subject goods" from China and "recommended imposition of definitive anti-dumping duty on imports" in order to "remove injury to the domestic industry."
India had imposed the restrictive duty on melamine for the first time in November 2004. In 2008, DGAD initiated the sunset review in the matter of continuation of anti-dumping duty on imports and in 2010 the duty was imposed.
After the complaint of the domestic industry, the authority initiated the second sunset review investigation in December 2014 to review the need for continued imposition of the duties.
Melamine imports from China have increased from 17,580 tonnes in 2010-11 to 30,780 tonnes during April 2013 to June 2014.
