Mechanically, this Tariff Concession Order (TCO 0703434) declares that thermoelectric wine coolers (Customs Tariff 8418.29.00) with capacity not greater than 140 litres are to be treated under Item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995, effective 2 March 2007 until revoked under ss 269SC/269SD. It therefore changes the tariff classification that applies on import. This affects importers (who face the altered tariff treatment), customs officers (who apply and can revoke the concession), and businesses whose import costs and compliance obligations depend on that classification.
