What this does: This order cancels a previous import duty exemption (Tariff Concession Order 0839795) for specific industrial equipment.
The goods affected: Expansion joints used in steam generation boilers at alumina plants, classified under tariff code 8307.10.00.
Why it matters: Importers of these expansion joints must now pay customs duty on them. Under the Customs Act, tariff concessions are revoked when an Australian manufacturer starts producing equivalent goods locally—so this likely reflects new local manufacturing capability.
Timing: The revocation took effect on 17 December 2009, meaning the duty exemption stopped applying from that date.
