This Order, effective 26 Sept 2011, declares that certain portable jump starters (tariff classification 8507.10.90) that include at least two listed features qualify for Schedule 4 item 50 of the Customs Tariff Act 1995. Mechanically, that makes those imported goods eligible for the tariff concession set out in Schedule 4 — a change that directly affects importers (who may pay a lower duty), customs administration (who applies the concession), and competing suppliers. The concession continues until revoked under the cited revocation provisions.
