How We Calculate Prices and the Standards Used

Prices between the reference grades are worked out in a straight line from our four reference prices: GAR 3,400 (US$46.64), GAR 4,100 (US$69.28), GAR 5,300 (US$97.85) and GAR 6,322 (US$125.60) per metric ton.

The price rises by a fixed amount for each extra kcal/kg in each range. Low range (3,400–4,100): US$0.0323 per kcal/kg, about US$3.23 per 100 kcal/kg. Mid range (4,100–5,300): US$0.0238 per kcal/kg, about US$2.38 per 100 kcal/kg. High range (5,300–6,322): US$0.0272 per kcal/kg, about US$2.72 per 100 kcal/kg.

Gross energy: ASTM D5865 / ISO 1928 Net energy: ISO 1928 Total and inherent moisture: ASTM D3302 / D3173 Ash, volatile matter, fixed carbon: ASTM D3174 / D3175 / D3172 Sulfur: ASTM D4239 Grindability: ASTM D409

This is an estimate of the FOB cargo value. The final contract amount is based on the weight actually measured and any price adjustment for energy content from the certified COA.

Contract Terms

Standard terms for international coal sales contracts

Price Basis and Delivery Terms

The prices shown are in US dollars per metric ton, Free on Board (FOB) Mother Vessel: coal loaded onto your ship at the Taboneo or Muara Berau anchorage in Kalimantan. Quotes for FOB Barge, CFR and CIF are adjusted for current shipping costs, tugboat and barge charter rates, and cargo insurance rates.

Price Adjustment for Energy Content

The final payment follows the price adjustment formula in the contract, based on the certified quality certificate (COA) issued at the loading port. If the tested energy content is different from the contract but within the allowed range: Adjusted Price = Contract Base Price × (Tested GAR ÷ Contract Base GAR).

Independent Quality Certificates

Cargo weight and quality are certified at the loading port by certified international independent inspectors (SGS, Sucofindo or Carsurin). The quality certificate (COA) and weight certificate (COW) they issue are the binding basis for payment under the Letter of Credit.

Payment and Security

Payment is secured by an Irrevocable Letter of Credit (L/C) at sight, issued or confirmed by a major international bank, or by bank transfers (T/T) made in stages at agreed milestones, under Indonesian coal export rules (PP No. 21/2026 DHE SDA).
