The defence offset policy mandates the foreign suppliers to plough back a minimum of 30 per cent of the contractual value of projects worth Rs. 300 crores or above to the domestic defence industry. The offset route is intended to strengthen the domestic defence industrial base through a combination of technology transfer, investment in R&D and in production facilities, besides export business generation. From the national view point, the offset aims self-reliance and indigenous capability enhancement in the vital defence sector involving advanced technology.
