This Order declares that "gravimetric coal feeders" classified at tariff code 8428.90.00 are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 6 December 2005 until revoked. Mechanically, it changes how those imported goods are treated under the tariff schedule. It affects importers, customs brokers and suppliers who must classify and document goods correctly to rely on the Schedule 4 treatment; the instrument was made by a delegate of the Chief Executive Officer and creates administrative compliance and duty‑outcome consequences.
