Under s269P (Customs Act 1901), this Order applies Schedule 4 item 50 of the Customs Tariff Act 1995 to a listed set of glasshouse-structure parts (gutters, ridges, posts, plates, profiles, strips, roof/gable bars, supports, brackets, connectors, flashings, clamps, clips, vents, water collectors). Effective 28 June 2010 until revoked. It changes which imported goods qualify for the Schedule 4 tariff treatment, so importers and customs brokers face different duty outcomes and documentation requirements; the CEO's delegate decides entitlement and importers must demonstrate the goods match the descriptions.
