Supply. Kolkata cement comes mainly from the Chhattisgarh (Baloda Bazar) and Jharkhand belts plus eastern-region grinding units; TMT is well-supplied from the SAIL/Bhilai and local eastern mills, and aggregate is railed in from Jharkhand and Odisha quarries since the Bengal delta has no hard rock. For bricks & blocks specifically, this places Kolkata on the favourable side of the national cost band — the page's table reflects 6 % below the 50-city national average.
What moves the local price. the alluvial Ganga-delta geology means zero local stone — all coarse aggregate bears a long rail/road haul, structurally lifting concrete cost; river sand from the Damodar and Rupnarayan is available but increasingly regulated.
Buyer takeaway. steel is a relative bargain here owing to the SAIL/Bhilai supply chain, but aggregate carries one of India's higher haulage premiums — staging stone at a Howrah/Dankuni rail siding is the standard cost-control move for big pours. Cross-check the bricks & blocks ranges in the table above against a live local quote before raising a purchase order — the spread between bulk-dealer and retail rates in Kolkata, West Bengal is wider than the table's midpoint suggests.
Masonry units in India follow IS 1077 (clay bricks), IS 2185 (concrete masonry), IS 13990 (fly-ash bricks), and IS 2572 (AAC blocks). Traditional red clay bricks (230×110×70 mm) have been the default for centuries but are being displaced by AAC (Autoclaved Aerated Concrete) blocks in urban multi-storey construction — AAC is 4-5× lighter (600-700 kg/m³ vs 1,800 for clay), improves thermal performance, and speeds up masonry work by 40-50 %. Fly-ash bricks (IS 12894) are the cheap alternative to clay in regions with thermal-power plants nearby. Hollow and solid concrete blocks serve for boundary walls, external leaf, and retaining walls.
Red-clay brick prices have risen ~10-15 % YoY since 2022 as many states restrict clay mining and force kilns to zigzag-technology upgrades. AAC block prices have stabilised after initial volatility, as capacity expanded with major brands adding plants in Gujarat, Tamil Nadu, and Telangana. 2026 pricing sees AAC 6 inch at ₹40-60 per piece in major metros, red clay at ₹8-12 per piece, and fly-ash at ₹5-8 per piece.
