Tata Chemicals has announced that its Board of Directors, at a meeting held on May 4, 2026, approved an investment of ₹100 crore towards debottlenecking salt capacity at its Mithapur plant by 82,500 TPA. The investment specifically targets Iodised Vacuum Salt Dried (IVSD) — a vacuum-evaporated, iodine-enriched salt variant — and is driven by growing demand for this product. The board meeting commenced at 3:00 p.m. (IST) and concluded at 5:40 p.m. (IST), with the intimation filed under Regulations 30 and 51 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

Board-Approved Capacity Expansion

The Mithapur plant currently operates an existing IVSD salt capacity of 1.60 MTPA (million tonnes per annum) at a utilisation rate of 92%, indicating that the facility is running close to its operational ceiling. The approved capacity addition of 82,500 TPA is expected to be completed over the next 12 months and will be financed through various options, including internal accruals. The key details of the approved investment, as disclosed under Regulation 30 and Schedule III of the SEBI Listing Regulations, are outlined below:

Strategic Focus on Mithapur Operations

The Mithapur plant has long been central to Tata Chemicals' salt production activities. The high existing utilisation rate of 92% underscores the operational necessity of this capacity addition to sustain supply and meet incremental market demand. By channelling ₹100 crore into this facility, the company aims to meaningfully expand its IVSD manufacturing throughput. The addition of 82,500 TPA in capacity represents a structured step toward meeting production objectives at the site, with financing to be managed through internal accruals alongside other available options.
