What this does: This document cancels a previous rule that allowed certain concrete mixing plants to be imported into Australia without paying customs duty (tariff).
Who it affects: Companies that import industrial "wet mix concrete mixing and batching plants" — specifically equipment that includes integrated storage bins, concrete mixers, weighing systems, and cement conveyor screws.
The practical effect: Before this revocation, importers could bring this machinery into Australia duty-free under Tariff Concession Order 0940167. Now, anyone importing this equipment must pay the standard customs duty that applies to goods classified under tariff code 8474.31.00.
Timing: The cancellation takes effect from 18 January 2010 (retrospective to that date), even though the document was signed on 4 March 2010.
