Mechanically, this Order (s269P) declares ceramic electric power-transmission insulators (Tariff 8546.20.00) are goods to which item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies, effective 6 Aug 2007 and continuing until revoked (ss269SC/269SD). It changes tariff treatment on import: importers and suppliers bear any duty consequences; the decision was taken by a Chief Executive Officer delegate (Wendy Knowles). Importers must classify and declare these goods under the Order; Customs enforces compliance.
