This Order treats a specific product — "bearing housings, ball mill, weight not less than 350 kg" (tariff heading 8483.30.90) — as eligible for Schedule 4 item 50 concession under the Customs Tariff Act 1995, effective 3 December 2009. It affects importers of those heavy bearing housings by changing their tariff treatment, and it matters because importers must claim the concession and Customs can revoke it under ss.269SC–269SD, altering import costs, administrative steps and incentives for suppliers and buyers.
