COMMODITY PRICES ADJUSTMENT
International merchandise trade exports data (on a recorded trade basis) presented in tables 12-15 of this publication are based on information provided by exporters to the Australian Customs and Border Protection Service (Customs and Border Protection). At the time of initial reporting to Customs and Border Protection the final prices may not be known for some commodities. New contract prices that have been recently negotiated, or are still being negotiated, for commodities like iron ore and coal may not be fully reflected in the Customs and Border Protection source data. Final prices are updated progressively in recorded trade data as exporters revise the information provided to Customs and Border Protection.
A negative $80m adjustment has been applied to the value of 'metal ores and minerals' in the balance of payments series for November 2010 to take into account additional information on the unit price of iron ore exports. No adjustment has been applied to the 'coal, coke and briquettes' component. All price adjustments previously applied to these components have been removed.
In the unadjusted recorded trade series, the unit price of metal ores and minerals increased 3% between October and November 2010. In the equivalent adjusted balance of payments series, the unit price of metal ores and minerals increased 2%.
