Cement firms across India have raised cement prices by Rs.10-40 per bag in October as input costs have inflated. According to cement dealers, the rise in prices is higher in Mumbai and Gujarat area, where the increase is Rs.40 per bag, while in North and South India, the surge in costs is about Rs.10-20 per bag. A cement bag weighs 50 kg, and the average cost of a cement bag is about Rs.375 across India. Analysts said that while the input price inflation is one of the reasons for the cement firms to raise costs in October, an increase in demand coming from the realty sector and the government's push on infrastructure is another reason.
