COAL - BEIJING. China's coal imports from Indonesia, its largest supplier, fell 30% year-on-year in June, customs data showed on Sunday, outpacing a decline in total coal imports as buyers shifted away from coal with lower heat content.

Indonesian imports were 11.62 million metric tons in June. For the first six months of the year, China imported 90.98 million tons of Indonesian coal, down 12% from the same period a year earlier, the data showed.

A global fall in coal prices has made higher-quality coal, which yields more energy per ton, more cost-competitive.

That has hurt demand for Indonesia's lower-heat supply. The shift to coal that yields more energy per ton, along with a ramp-up in domestic production in China, has reduced overall import tonnage.

In June, China's coal imports from all sources fell to 33.04 million tons, down 26% year-on-year and the lowest monthly level in more than two years, customs data showed earlier this month.

For the first half of 2025, China's total coal imports were down 11% year-on-year at 221.7 million tons.
