This Order (made under s269P of the Customs Act 1901) applies Schedule 4, Part III item 50 to a specific class of high‑pressure blasting guns (8424.20.00) from 14 September 2011 until revoked. It affects importers (who benefit from the tariff concession) and the Commonwealth’s tariff revenue. A delegate of the Chief Executive Officer declares the concession and revocation is governed by ss 269SC/269SD. Mechanically it changes tariff treatment on import declarations and imposes a classification and documentary compliance obligation.
