The Union Food Ministry has suggested imposing a 5 percent GST on de-oiled rice bran to discourage use of the product for feed purpose, Food Secretary Sudhanshu Pandey said. "We have written to the Finance Ministry to impose 5 percent GST on de-oiled rice bran," Pandey said at a press conference.The issue will be decided in the GST Council, he added. Amid increased dependence on edible oil imports, the country needs to increase the domestic production of rice bran oil as now only 60 percent of the capacity is being utilised.
