This Order applies item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 to a specific class of air compressors: volumetric rotary‑vane compressors with operating pressure not greater than 700 kPa and free air delivery not greater than 3 m3/min. It takes effect 25 February 2011 and remains until revoked under the Customs Act 1901.
Importers and buyers of these compressors are affected because qualifying imports receive the Schedule 4 tariff treatment; importers must confirm the precise technical limits to qualify.
