This Tariff Concession Order declares that plastic sponges (Customs Tariff classification 3924.90.00) are goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 12 November 2008. The declaration remains in force until revoked.
It directly affects importers and customs processing for those goods; the delegate exercised power under section 269P and revocation may occur under sections 269SC or 269SD, so administrative compliance and reliance on the Schedule item's legal treatment are the principal practical effects.
