This Order (made under s.269P of the Customs Act 1901) declares that "liners, alumina ceramic, whether or not in tile form" classified at tariff heading 6909.12.00 are goods to which Part III, Schedule 4, item 50 of the Customs Tariff Act 1995 applies, effective 17 July 2008. The delegate of the CEO made the decision; the Order remains in force until revoked under ss.269SC or 269SD. Importers are the primary parties affected because the Order changes which Schedule 4 treatment customs applies to these imports.
