The Trade Import and Export Classification (TRIEC), has been developed by the Department of Foreign Affairs and Trade (DFAT) as a means of classifying Australia's and international merchandise imports and exports by level of processing.

TRIEC is made up of three broad categories:

• Primary products - classified as either Unprocessed or Processed
• Manufactured products - classified as either Simply transformed (STM) or Elaborately transformed (ETM), and
• Other goods - mainly Non-monetary gold and Confidential trade.

TRIEC is a hierarchical classification, with the broadest classes of goods defined at the 1-digit level, with progressively finer disaggregation down to a 4-digit level.

DFAT publishes merchandise trade data on a TRIEC basis in the Composition of Trade, Australia publication and related pivot tables on a financial year and calendar year basis.
