Indonesian Coal
Product Description
MA Associates supplies Indonesian Coal, a widely traded thermal (steam) coal sourced from the coal-producing regions of Indonesia, mainly Kalimantan and Sumatra. Indonesian thermal coal is available in a broad range of calorific value grades, making it a flexible fuel option for industrial and commercial buyers in Pakistan.
Indonesian Coal is generally known for its low sulphur content and, in many grades, low ash content. Lower-rank grades typically carry higher moisture, while higher-rank grades offer greater calorific value. Selecting the right grade depends on your boiler, furnace, or kiln design, fuel-handling system, and cost targets.
At MA Associates, we aim to help buyers choose a suitable Indonesian coal grade according to their technical requirements, intended application, order quantity, and delivery needs. Final specifications are agreed in the contract and verified through laboratory analysis and inspection documents.
Key Features of Indonesian Coal
- Wide Range of Grades: Thermal coal grades from roughly 3,400 to 6,500 kcal/kg GAR, so buyers can balance heating value against price.
- Low Sulphur: Typically lower sulphur levels than many coals from other origins, subject to the specific mine and grade.
- Low to Moderate Ash: Many grades are supplied with ash levels in the single digits, depending on the grade.
- Bulk Supply: Shipment arrangements for industrial buyers, wholesalers, and traders.
- Specification-Based Supply: Calorific value, moisture, ash, sulphur, and size agreed according to buyer requirements.
- Quality Verification: Laboratory analysis and independent inspection arrangements can be discussed as part of the order.
Indonesian Coal Specifications
Indonesian thermal coal is commonly traded by calorific value on a Gross As Received (GAR) basis. The table below shows indicative market specifications for the most commonly traded grades. Actual values depend on the mine and shipment and should be confirmed through a laboratory test report.

Figures shown are indicative market specifications for commonly traded Indonesian thermal coal grades and are not a guarantee of any shipment. Actual values vary by mine, seam, and cargo, and all terms must be confirmed in the contract and by a laboratory test report.
Applications of Indonesian Coal
Depending on the grade and the design of the combustion system, Indonesian Coal may be considered for:
- Cement plants and other kiln-based manufacturing
- Coal-fired power generation and captive power plants
- Industrial boilers for textile, paper, food, and chemical processing
- Brick kilns and other compatible kilns
- Furnaces and thermal processing units
Lower calorific grades usually contain more moisture and may need equipment designed for them, while higher calorific grades suit applications that need greater heat output. Buyers should confirm that the coal’s calorific value, moisture, ash, sulphur, and size are compatible with their equipment before purchase.
