This Tariff Concession Order (made under s269P of the Customs Act 1901) declares that goods classified 8428.90.00 — “SYSTEMS, POSITIONING, TIMBER SAWLINE” — are goods to which the item in Part III of Schedule 4 (Item 50) applies, effective 26.04.07 until revoked (ss269SC/269SD or date in Column 2). Mechanically, it alters customs tariff treatment for importers of those sawline systems (affecting who pays duties and claims the concession); the declaration was made by a CEO delegate (Michael Perry) and administrative discretion to revoke or modify the order remains under the Act (ss269SC/269SD).
