The anti-dumping duty has been imposed following the findings of designated authority which concluded that imports of Vitamin-C have caused injury to the domestic industry.
"The anti-dumping duty...Shall be applicable to all synonyms of Vitamin-C, including...Ascorbic Acid, L-Xyloascorbic Acid, 3-Oxo-L-gulofuranolactone (enol form), L-3-Ketothreohexuronic Acid Lactone, etc," the Central Board of Excise and Customs (CBEC) said in a notification.
It further said that the anti dumping duty of USD 3.74 per kg will continue for five years unless revoked earlier.
Following a review of the anti-dumping duty in June 2015, the designated authority concluded that "should the present anti-dumping duties cease, dumping of the subject goods from the subject country is likely to get intensified causing consequent injury to the domestic industry".
It also said that "dumped imports have caused injury to domestic industry in the period of investigation".
Overall Vitamin-C imports in powder form amounted to USD 2.3 million in 2014-15. While the figure for Vitamin-C in tablet form stood at USD 1.3 million.
