DSI will forward at least one Indonesian coal exporter to the Trade or Finance Ministry for sanctions over a suspected price or volume mismatch by 30 June 2027, with significant publicity.

The Trade Ministry's new regulations require a surveyor's report on every coal shipment, plus an electronic report on each export whether or not it happens. Customs filings feed the state export company's database, which checks each price against global coal indices. As Indonesia sells many coal grades, often to related buyers, a system built to compare prices will produce outliers. With the government having designed it to catch under-invoicing, it will use a highly publicised case, whether merited or not, to demonstrate that the new state-controlled export model is successfully defending Indonesian coal prices. Coal exporters will have to brace for increased pricing scrutiny.
