Tamil Nadu’s government bans the transport of certain “rough stones” and construction materials to other States for three months, according to reports from both outlets. The restriction covers materials listed as rough stones, including khandas and boulders, as well as construction-related inputs such as M-sand, metal jelly, ballasts, mill stones, hand chakais, and building and road construction stones. The stated objective is to ensure adequate availability of construction materials within Tamil Nadu during the restriction period. The measures are presented as a supply-management step rather than a change in production within the State. The ban applies to outbound transport from Tamil Nadu to other States, limiting movement of these listed materials outside the State for the duration of the order. The reports describe the action as time-bound, lasting three months, and grounded in the government’s aim to maintain sufficient construction-material supply for ongoing and planned work in Tamil Nadu.
