Shares of MTAR Technologies, Larsen & Toubro (L&T) and Walchandnagar Industries rise following a government relief on duties for nuclear-related imports. The move comes after a notification from the Ministry of Finance stating that no customs duty is required for specified goods imported for nuclear energy generation during a defined period. The notification covers imports made between 1 April 2019 and 31 January 2026, providing the relief over several years rather than a short window. The announcements and subsequent market reaction reflect expectations that the duty waiver could reduce import-related costs for companies involved in supplying or supporting components used in nuclear energy projects. The reporting describes the rally as a direct response to the finance ministry’s notification on customs duty. Overall, the sources present the development as a policy change affecting nuclear energy generation imports, with investors reacting to potential impacts on expenses and project feasibility for businesses in the sector.
