China imported 5.08 million tonnes of coal from top supplier Australia in January, down 47.3 percent from a year earlier, with shipments disrupted by quality inspections at Chinese ports as well as falling demand.

Imports from Indonesia, China’s second biggest supplier, fell 56.6 percent to 3.2 million tonnes, data from the General Administration of Customs showed on Friday.

Total imports, excluding lower quality lignite, fell 51 percent in January to 13.6 million tonnes, according to the data. Earlier figures, which included lignite, put total shipments at 16.78 million tonnes, down 38.4 percent on the month.
