This Order, effective 18 November 2009, declares that imports classified 8431.43.00 — shock and vibration absorbing tools for oil and gas wells with stacked disc springs and a splined mandrel — are subject to Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 under authority of s269P of the Customs Act 1901. It gives those imports a tariff concession until revoked under ss269SC/269SD. Importers lower their costs; the Commonwealth forgoes tariff revenue. Customs must verify the narrow product description, creating a limited compliance and administrative task.
