This order declares that specific water‑injection skids for gas turbines (customs classification 8413.70.90) are goods to which Part III of Schedule 4, item 50, of the Customs Tariff Act 1995 applies. Effective 7 Jan 2009 until revoked, the declaration (made under s.269P) changes the tariff treatment applied at import. The decision reduces or alters import costs and creates classification and compliance obligations for importers, while relying on administrative revocation powers (ss.269SC/269SD).
