This Tariff Concession Order (effective 18 Oct 2010) applies Schedule 4, Part III, item 50 of the Customs Tariff Act 1995 to specific carbon‑steel tube fittings (couplings, reducers, bends, T‑junctions, union connectors and adaptors) with internal and/or external zinc coating not greater than 8 micron, classified at 7307.99.00. Importers benefit from the applied Schedule 4 concession; the order was made by a CEO delegate under s269P and can be revoked under ss269SC or 269SD, so accurate classification and Customs compliance rest with importers and Customs.
