This Order designates "tube connectors" classified under tariff subheading 8205.59.00 as goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, changing their tariff treatment from 13 September 2005 until revoked (see s.269P; revocation ss.269SC–269SD). Importers using that tariff classification can claim the Schedule 4 concession (lowering customs duty); the CEO (or a delegate) controls grant and revocation, so correct classification and documentation are required to obtain the benefit.
