This Tariff Concession Order lists specific parts for waste oil‑fuelled air heaters (tariff classification 7322.90.00) and declares they are goods to which Part III, Schedule 4, Item 50 of the Customs Tariff Act 1995 applies. It takes effect from 22 May 2006 and continues until revoked under sections 269SC or 269SD. Made under section 269P by a delegate of the CEO (Douglas Parker‑Barnes), it alters the tariff treatment that applies to the listed goods and therefore affects those importing or trading in those parts.
