Mechanically, this Order (under s.269P of the Customs Act 1901) makes safes for data storage classified at tariff heading 8303.00.00 subject to item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995, so the Schedule 4 tariff concession applies to those imports from 11 May 2009 until revoked. The declaration was made by a delegate of the Chief Executive Officer (Paul Mercer); affected importers receive the concession, and revocation can occur under ss.269SC or 269SD. Compliance depends on correct tariff classification and record-keeping.
