Under the GST regime, if a price of a product has increased the manufacturer/ importer/ packer will have to give an advertisement in two newspapers about the new MRP and put a revised sticker on the packaging.
Both the new and the old MRP must be shown on the packaging.
For products whose prices have come down under the new tax regime, no newspaper advertisements would need to be published.
However, a sticker mentioning the new MRP is a must, and the old price should show too on the packaging.
Packing material being costlier, so it has been allowed to be used in the existing stock upto September, by just putting a new MRP sticker.
The government has given time till september 2017 to reprint the revised MRP under the Packaged Commodities Rules !!
