This Order declares that bench-top laboratory block heaters with solid-state control, over-temperature protection, interchangeable or fixed sample blocks, and a colour touchscreen or push-button LCD (tariff code 8419.89.90) are goods to which Schedule 4, Part III, item 50 of the Customs Tariff Act 1995 applies, effective 7 May 2009 until revoked (made under s269P; revocation permitted under ss269SC/269SD). Mechanically, it changes the tariff treatment for importers of those specific heaters, requires importers to demonstrate the goods match the technical description, and vests application and revocation authority in a CEO delegate (Michael Perry).
