Tariff Concession Order 1006744 (under s.269P of the Customs Act 1901) declares electronic fire/heat detectors (tariff classification 8531.90.90) to be goods to which item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies, effective 8 Feb 2010. Made by a delegate of the CEO (David Mulcair), it changes the tariff treatment that applies to importers of those detectors until revoked (ss.269SC/269SD), altering importer costs, sourcing incentives and the requirement to comply with customs classification and concession rules.
