The PDS procures staple foods like rice and wheat and distributes them through a network of over 462,000 fair price shops to millions of Indian families with ration cards. It describes the key entities involved, including central and state governments, traders who operate fair price shops, and consumers. It then outlines the logistical processes of procurement, storage, transportation, bulk allocation, distribution to shops, and purchases by consumers at subsidized prices. The goal of the PDS is to ensure food security for the people of India.
