According to shipping data compiled by Argus Energy, Port Waratah Coal Services (PWCS) shipped 1.5 million metric tons (mt) to China, and Newcastle Infrastructure Group (NCIG) exported 1.8 million mt in April. By comparison both firms shipped around 1 million mt of coal to China in March, up from around 600,000 mt in February as Beijing’s informal ban on Australian coal imports ended, according to the shipping data. The vessel queue of ships has grown to 15 from nine at the end of March, according to Argus Energy, from a three-year low of seven at the end of February, but is still lower than the average of 28 ships in 2022.
