This Order applies Schedule 4 item 50 of the Customs Tariff Act 1995 to specific oven lamp assemblies classified at tariff heading 8516.90.00, effective 23 March 2010. It changes the tariff treatment at import for those goods, so importers of such high‑temperature oven lamp assemblies face a different duty outcome. The decision is made by a customs delegate under s.269P of the Customs Act 1901 and the concession remains until revoked under ss.269SC or 269SD, giving administrative discretion over duration.
