International merchandise trade exports data presented in this publication are based on information reported by exporters to the Department of Home Affairs (Home Affairs). At the time of initial reporting to Home Affairs, the final prices at which transactions take place are not known for some commodities. Final quantity and/or unit price information is updated progressively in international merchandise trade data as exporters revise the information provided to Home Affairs.
For commodities such as iron ore and coal, newly negotiated contract prices are not fully reflected in data first reported to Home Affairs. When additional information on quantity and/or unit price for these commodities is available, the ABS may adjust the data to reflect actual transaction values.
Iron ore adjustments are applied on an international merchandise trade basis at the Australian Harmonized Export Commodity Classification (AHECC) level. Coal, coke and briquettes are adjusted on a balance of payments basis in current price, original terms. When actual final transaction prices become available estimates are replaced with these data.
In most instances, transfer of ownership occurs when goods cross the customs frontier. In certain circumstances the ownership of large value capital expenditure items can occur prior to the items crossing the customs frontier. The ABS may adjust the relevant balance of payments series to record the timing when transfer of ownership was affected.
