Mechanically, this Order makes stainless‑steel delta‑blade mixers (tariff 8479.82.00) with capacity ≥1,950 litres eligible for Schedule 4 Item 50 tariff treatment from 9 June 2009 until revoked. It affects importers (who may pay lower or no customs duty when Item 50 applies), the customs administration (which applies and can revoke the concession under the Customs Act), and competing domestic suppliers. The change alters import price signals and leaves an administrative revocation pathway under sections 269SC/269SD of the Customs Act 1901.
