Corner Stone exports Indonesian steam coal, a non‑coking thermal grade sourced from South Kalimantan. The product is offered in two calorific bands: GAR coal ranging from 3 800 to 6 800 kcal kg⁻¹ and NAR coal from 3 400 to 6 400 kcal kg⁻¹, as measured on an air‑refined basis. The supplier states a monthly supply capability of 50 000 to 300 000 tonnes and a minimum contract of 50 000 tonnes per year.
Typical steam coal from Indonesia contains moisture between 5‑12 % and ash content of 10‑20 %, values that align with the figures commonly accepted for power‑plant fuel. The coal is generally sized below 50 mm and has a bulk density around 0.9‑1.1 t m⁻³. Washing is standard practice to reduce surface impurities, although the listing does not detail a specific washing process.
Primary users include utility generators, independent power producers and large‑scale industrial boilers that require a steady heat input. Corner Stone arranges shipment via the port of South Kalimantan and offers inspection by SGS or CCIC, with payment typically through US‑L/C. Prospective buyers should discuss incoterm preferences, vessel size and any required certifications during the negotiation stage.

Importers should first verify Corner Stone’s corporate registration and request a recent assay report confirming calorific value, moisture and ash levels. Checking the harbour trust tier and confirming the supplier’s banking references can further reduce transaction risk. It is also advisable to obtain a copy of the washing process description to ensure consistency across shipments.
Logistics for Indonesian steam coal usually involve loading at the South Kalimantan port; buyers need to confirm the exact berth, vessel size and expected loading window. Discuss lead‑time expectations, preferred Incoterms such as FOB or CIF, and any freight forwarder arrangements. Payment via US‑L/C should be aligned with the agreed documentary requirements and credit period.
Quality control typically includes third‑party inspection by SGS or CCIC before loading. Arrange sampling according to ISO 18287 and request a Certificate of Analysis covering moisture, ash, sulphur and calorific value. Retain all inspection certificates, shipping documents and laboratory reports to satisfy customs authorities and future quality audits.
