This Order declares that certain vehicle‑mounted concrete boom-placing pumps — specified by weight (>45,000 kg), axle count (not less than 6) and boom reach (>50 m), and classified 8705.90.00 — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It takes effect from 25 July 2007 until revoked. The declaration changes how these imported machines are treated under that Schedule and therefore affects importers who must match shipments to the description to rely on the Schedule 4 item.
