The main suppliers of iron ore in India are MMTC, KMMI, MSPL, and NMDC. Among them, the export of Indian ore with a grade of more than 64% must be exported through MMTC. Major state-owned mines in India include: National Mining Development Corporation (NMDC), Steel India Administration (SAIL) and Kudremukh Iron Ore Company (KIOC). These companies are industry giants and control the production of iron ore. There are many companies in private mines, the most important of which is Tata Steel, a comprehensive steel company with an annual iron ore output of 6-7 million tons, mainly from the Noamunid and Joda East mines. All manufacturers have the ability to export, but they are relatively independent. Japan was originally the largest buyer of Indian iron ore, but its share has now dropped to about 33%. In addition, South Korea and Taiwan are the other two major buyers of Indian iron ore.
