Why Surat, why now
India's chip, solar and diamond industries are being built here.
IESS brings the buyers and suppliers of electronics and semiconductor materials into one focused room, a short drive from the fabs, OSATs and solar lines now rising across Gujarat.
Semiconductor
6
approved semiconductor projects in Gujarat, worth about ₹1.24 lakh crore, from Tata's Dholera fab to OSATs by Micron, Kaynes, CG Semi and Suchi Semicon.
Solar
~45%
of India's 261.7 GW solar module capacity is in Gujarat, with 37% of cell capacity, as of June 2026.
Diamond
~90%
of the world's diamonds are cut and polished in Surat, whose growers are now moving into technical-grade diamond.
Three themes, one supply chain
