This Tariff Concession Order treats air‑conditioning condensate pumps (tariff classification 8413.50.90) as goods covered by Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 8 Dec 2010 until revoked. A delegate of the CEO made the declaration under s.269P of the Customs Act 1901. Mechanically, importers can rely on the Schedule 4 concession (reducing or removing customs duty) so the Commonwealth foregoes that tariff revenue; compliance requires correct classification and revocation can occur under ss.269SC/269SD.
