This Tariff Concession Order (under s.269P of the Customs Act 1901) declares that halogen-light enclosures (mineral wool, fire‑rated) classified at 8547.90.00 are goods to which Item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies, effective 29 April 2009. Mechanically, it changes the tariff treatment applied to those imported goods. A delegate of the CEO made the decision; importers must correctly classify and describe the goods to rely on the concession, and the Order can be revoked under ss.269SC or 269SD.
