This Tariff Concession Order declares that "filters and/or separators, zinc concentrate slurry" (tariff code 8421.21.90) are goods to which Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 22 October 2008 until revoked. It was made under section 269P by a delegate of the Chief Executive Officer.
Mechanically, it alters import treatment for those specific goods by attaching Schedule 4 item 50; importers must correctly classify the goods and claim the Schedule 4 treatment, and the CEO’s office can revoke the Order under sections 269SC or 269SD.
