Under s.269P of the Customs Act 1901, this order treats electronic detonators (tariff heading 3603.00.00) as goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 2 Sept 2005. That makes importers of these detonators eligible for the tariff concession set out in Schedule 4 item 50.
The concession remains until revoked under ss.269SC or 269SD; the CEO (by delegate) controls application and revocation. Importers must correctly classify goods and meet any conditions to obtain the duty treatment, creating administrative compliance and revocation risk.
