Iran's government is considering imposing a tax of up to 40 percent on iron ore exports to benefit from the increase in iron ore sales to China, according to Reuters.
During the first quarter of the current year, Iran's iron ore exports to China improved by 48 percent year on year which translates into a revenue of $3 billion at current prices.
According to Reuters, Iran has become China's fourth largest iron ore supplier, since another major supplier India had to cut down iron ore exports to prevent illegal mining activities. Iran exported 5.68 million mt of iron ore to China in the first quarter, accounting for only three percent of China's total iron ore imports during the given period.
