This Order, made under s.269P of the Customs Act 1901, applies Schedule 4 item 50 to parts described as condensers for split‑system reverse‑cycle air‑conditioners (tariff classification 8415.90.00), effective 18 August 2006 until revoked. It lets importers claim the Schedule 4 concession for those parts; the Commonwealth foregoes the corresponding tariff revenue and customs administers eligibility. The Order may be revoked under ss.269SC/269SD and eligibility turns on tariff classification and customs assessment.
