1 Calculated CSR = globalCOAL HCCA MV CSR formula:
425.4*MMR-150.2*(MMR)2+4.87*Log(MF)-12.35*MBI+2.58*MBI*Log(MF)-237.6

Log(MF) = Log10 (Maximum Fluidity). Log (MF) of >3.50 must be entered as 3.50
Modified Basicity Index (MBI) = ((Fe2O3+K2O+Na2O+CaO+MgO) / (SiO2+Al2O3)) x Ash (db) / (100-VM (db)) x 100

See our Met Coal Calculators to help calculate CSR and the final price of coal delivered.

The following brands are deliverable under the specification for HCCA Branded Transactions:
Goonyella, Moranbah North, Illawarra, Oaky Creek, North Goonyella
Each is a 'Branded Metallurgical Coal' as defined in the HCCA RSS.

HCCLV FOB Australia Metallurgical Coal

Unlike other globalCOAL specifications, the HCCLV RSS does not prescribe rejection limits. Instead, the Seller must deliver one of the allowable brands, for which typical specifications are widely available, and evidence the Brand on the shipping documentation.


HCCLV deliverable Brands, as of 9 October 2019:


Price adjustments will apply on the following parameters:

  Basis Price Adj +/- Per From Basis
Total Moisture (AR) 10.0% 1.0% 1.0% 10.0%
