This Order declares that imported "drop bolts, bifold door" (Customs Tariff heading 8301.40.00) are subject to a Schedule 4 tariff concession (item 50), effective 18 November 2008. Made under section 269P of the Customs Act 1901 and revocable under ss 269SC/269SD, it lets importers claim reduced or exempt customs duty for the listed goods. The delegate of the CEO decided the concession; the government forgoes the equivalent duty revenue and importers must meet the administrative steps to claim it.
