This Order declares that parts for concrete pumps — specifically truck or lorry‑mounted placing booms (tariff classification 8413.91.90) — are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It takes effect from 2 February 2010 and continues until revoked (s269P; revocation under ss269SC/269SD). Importers of those parts can claim the Schedule 4 concession; the Commonwealth forgoes the corresponding tariff revenue, and the declaration was made by a delegate of the CEO (dated 23 April 2010).
