This Order says that certain prefabricated operating or intensive‑care unit rooms (tariff heading 9406.00.00) that meet the listed technical features qualify for the Schedule 4, Part III, item 50 tariff concession under the Customs Tariff Act 1995, effective 30 August 2010 until revoked. It affects importers of those modular hospital units (who receive the concession and therefore pay lower customs duty) and requires goods to match the stated specifications (antibacterial powder‑coated walls or glass panels; x‑ray protection ≥ 0.4 mm lead; hygienic, hermetically sealed connections). The instrument was made by a delegate under s.269P; revocation follows ss.269SC–269SD.
