This Order applies Part III, Schedule 4 Item 50 of the Customs Tariff Act 1995 to "ignition coils" classified at tariff heading 8511.30.00, effective 07.01.2010 until revoked. The instrument changes the tariff treatment that applies at import for those goods.
That matters to importers (who face the changed customs treatment), to customs administrators (who apply the classification and concession), and to businesses whose costs or pricing depend on the customs treatment of ignition coils (Order text; ss. 269SC/269SD referenced).
