What it does (mechanics): This Order declares that specific "rotators" used for precast concrete wall panels (precisely described by lifting capacity and components) are goods to which Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies, effective 3 May 2011. It therefore changes the tariff treatment for importers of those machines and can be revoked under sections 269SC/269SD. This creates a predictable tariff outcome for qualifying imports while requiring strict technical compliance and exposing importers to later administrative revocation.
