This order declares that a specific product—an “incremental bridge launching system” made up of hydraulic jacks, hydraulic drive units and control units (Tariff heading 8425.42.00)—is to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It takes effect from 02.10.2008 until revoked. The change mechanically alters how those imported goods are treated under the Customs Tariff (affecting import duty/tariff treatment and related compliance) and therefore matters to importers, customs officials and suppliers of that equipment.
