With our mining operations based in East Kalimantan we are producing a NAR4700 coal as our standard quality. In addition, we can supply NAR4500 and NAR4200 as standard products on a long-term basis.

With all three products we can guarantee the coal to meet the Chinese standards with regard to all regulated chemical elements as set forth by the Chinese Inspection and Quarantine Department (CIQ) and the "Interim Measures for the Administration of Commercial Coal Quality".

 

For any other coal specification, please send us your detailed specifications and required quantities and we will let you know in due course whether we are able to supply.
