This Tariff Concession Order (0506769) applies Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 to specified centrifugal-pump parts (casings; impellers; mag capsules; foot plates; rings; flanges), effective 6 June 2005 and continuing until revoked (made under s.269P of the Customs Act 1901). Mechanically, it changes tariff treatment at import — benefiting importers, potentially affecting competition and prices in downstream markets, and reducing Commonwealth tariff receipts; the delegate (Wendy Knowles) made the decision; compliance requires correct classification and documentation and revocation follows ss.269SC/269SD.
