What Our Buyers Say
Calorific value on every cargo landed inside the contracted band. The COA matched our own lab results at discharge, which is rare.
Nguyen Van MinhFuel Procurement Manager · Power Plant
Their team kept the laycan even during the rainy season. For a cement kiln, that reliability matters more than a few dollars per ton.
Rajesh IyerHead of Sourcing · Cement Plant
Documents were complete on first submission and the bank accepted the L/C presentation without discrepancies. Smooth from LOI to B/L.
Kim Ji-hoTrading Director · Trading Company
We started with a trial cargo of GAR 4200 and moved to a twelve-month contract. Quality has stayed consistent shipment after shipment.
Maria SantosSupply Chain Lead · Power Plant
Transparent HBA-linked pricing and quick answers from the export desk. They are now our core Indonesian supplier.

FAQ
Questions Buyers Ask Before Contracting
Clear answers on volumes, payment, inspection and pricing. Need something specific for your plant or tender?
Contact Our Sales TeamWhat is the minimum order quantity?
Barge cargoes start from about 7,500 MT (FOB Barge). Mother vessel cargoes are typically 50,000–75,000 MT per shipment.
Which payment terms do you accept?
Irrevocable L/C at sight from a prime bank is preferred. SBLC and TT structures can be discussed for long-term contracts.
Who inspects the coal and how?
An independent surveyor such as SGS, Sucofindo, Carsurin or Geoservices samples at loading port and issues COA, COW and draft survey reports.
What laycan and loading time can you offer?
Laycan is agreed per contract, usually a 10-day window. Loading rate depends on anchorage and weather; priority slots go to term buyers.
Is pricing based on HBA or ICI?
Either. Export pricing respects the government HBA reference, and commercial formulas can be indexed to ICI with quality adjustments.
Can we start with a trial shipment?
Yes. Trial cargoes are available for new buyers so your plant can test performance before a term contract.
