Maximum retail price (MRP) is a manufacturer calculated price that is the highest price that can be charged for a product sold in India and Bangladesh. However, retailers may choose to sell products for less than the MRP. MRP differs from systems using a recommended retail price because in those systems the price calculated by the manufacturer is only a recommendation, not enforceable by law. In April 2015, it was reported that milk vendors in Mumbai were threatening a boycott after it was discovered they had been charging above MRP and the Maharashtra state government threatened to intervene.
