Under section 269P of the Customs Act 1901, this Order treats specified fibreglass‑reinforced phenolic resin gratings (floor panels and stair treads) as goods to which tariff concession Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 17 October 2005. Importers of those goods are affected because the concession changes their customs duty treatment; the Order remains in force until revoked under sections 269SC or 269SD, so importers must claim the concession and meet customs classification and compliance rules.
