We supply thermal coal, arrange independent quality testing, and ship from mine to port under one contract with one accountable partner.
PT Intan Nusantara Indonesia supplies Indonesian steam coal directly to international power utilities and industrial consumers. We coordinate concession loading, independent analysis and marine logistics ourselves, without intermediary brokers.
We ship Indonesian steam coal straight from Kalimantan concessions in 8 grades, from GAR 3,400 to 6,300+ kcal/kg. Spot shipments and term contracts both run under Incoterms® 2020: FOB Barge, FOB Vessel, CFR or CIF.
Our trade desk advises international buyers, power utilities and industrial consumers. We cover pricing intelligence (ICI 1 to ICI 5), mine due diligence through Know-Your-Supplier (KYS) audits, boiler spec matching and contract review.
