This Order applies a Schedule 4 tariff concession (Item 50, Part III of the Customs Tariff Act 1995) to specified crane spreaders classified at 8431.49.90 — separating twin‑lift spreaders that are either rail‑mounted gantries or ship‑to‑shore. It takes effect from 23.05.06. Declared by a delegate under s269P of the Customs Act 1901 and operable until revoked under ss269SC or 269SD, it changes the tariff treatment importers face for these specific goods and relies on customs administration to apply and enforce the concession.
