Pre-packaged and labelled food items like curd, lassi and buttermilk will get costlier from July 18 as they'll attract 5% GST. Jaggery, khandsari sugar, puffed rice will no longer be exempt from GST. Kitchen utensils like knives, spoons, forks, and stationery items like pencil sharpeners, maps, globes and electrical appliances such as LED lights and fixtures will also get costlier.
