Import Direct Steam Coal — Buy in Bulk from Supplier in Indonesia

Direct steam coal from Subayu Minerals Indonesia is a bituminous coal sourced from East Kalimantan mines, with a gross calorific value typically between 5,200 and 5,800 kcal/kg. It has an ash content of 12% to 18%, moisture content below 10%, and sulfur levels under 1.2%. The coal is delivered in lump and run-of-mine sizes, with minimal fines, and is suitable for direct combustion in industrial boilers without preprocessing.

This coal is classified as medium-volatile bituminous and meets ASTM D388 and ISO 11760 standards for coal classification. The carbon content averages 65% to 70%, with volatile matter between 28% and 32%. It is low in phosphorus and chlorine, making it suitable for cement kilns and power plants requiring reduced emissions. The coal is not washed, so trace impurities like rock and shale may be present at levels below 3%.

It is primarily purchased by power generation facilities in Southeast Asia, cement manufacturers in Vietnam and Thailand, and industrial boiler operators seeking cost-effective fuel. Buyers typically order in lots of 10,000 to 50,000 metric tons per shipment. Packaging is bulk-loaded into containers or vessel holds. Delivery terms are offered as FOB Kalimantan or CIF port of destination. Lead time is confirmed per contract and depends on vessel scheduling.
