Under s.269P of the Customs Act 1901 a delegate declared that a specific machine — “edgers, plastic prescription lens, multi-function, computer numerical controlled” (tariff classification 8465.92.00) — is covered by Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 10 September 2009. The Order stays in force until revoked under ss.269SC or 269SD. Mechanically, this changes the tariff treatment applying to importers of the listed goods: importers face the duty outcome set by Schedule 4 rather than the default tariff.
