Import Coal Steaming — Buy in Bulk from Supplier in Indonesia

Coal steaming from Pt Seven Island International Gruop is a thermal fuel sourced from Indonesian mines, with a gross calorific value ranging between 5,000 and 5,800 kcal/kg based on the supplier's provided data. The moisture content is typically under 12%, and ash content does not exceed 18%, consistent with medium-grade bituminous coal used in industrial steam generation. This coal is delivered in lump and granular forms, sized for direct feed into boiler systems without requiring additional crushing.

The coal is classified as sub-bituminous to bituminous, with volatile matter content between 28% and 32%, supporting stable combustion in medium to high-capacity steam boilers. It contains low sulfur levels, generally under 1.5%, which reduces corrosion risks in boiler flues. While the supplier does not specify exact ASTM or ISO grade designations, the physical properties align with standard Indonesian thermal coal grades used in Southeast Asian power and manufacturing sectors. Packaging is in bulk or jumbo bags, suited for container or vessel shipment.

This coal is primarily purchased by industrial boiler operators in power plants, textile mills, and food processing facilities across Southeast Asia and the Middle East. Buyers require consistent calorific output and low slagging potential. Trade terms are typically FOB Tanjung Priok or CIF ports in the buyer's region. Minimum order quantities are not stated, but shipments commonly occur in containerized lots of 20 to 40 metric tons. Buyers should confirm ash fusion temperature and grindability index before procurement.
