This Order (under section 269P of the Customs Act 1901) declares that a specific model of rotary twin‑screw air compressors (tariff classification 8414.80.19) is a good to which Part III, Schedule 4, item 50 of the Customs Tariff Act 1995 applies from 11 Jan 2007 until revoked. Mechanically, it changes which tariff item governs those imports, lowering the importer’s tariff burden where item 50 provides a concession, creates an incentive to import those compressors, and requires correct tariff classification and recordkeeping.
