This Order declares that a specific part — non-ceramic lamp-mounting rails for fluorescent lamp fittings (tariff heading 9405.99.00) — is covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995. It takes effect from 17 March 2010 and continues until revoked under sections 269SC or 269SD of the Customs Act 1901. Importers of these parts must classify their goods to claim the Schedule 4 treatment; the concession changes the tariff treatment and thus affects import costs and pricing.
