This Order (made under s.269P of the Customs Act 1901) declares that vacuum calibrators for pipe-extrusion lines (single or twin chamber), tariff classification 8477.40.00, are subject to Schedule 4, Part III item 50 of the Customs Tariff Act 1995 from 28 June 2007 until revoked (s.269SC/s.269SD). Importers are the primary parties affected because the tariff treatment for these specific goods is altered; the instrument was issued by a delegate of the Chief Executive Officer (Michael Perry). Businesses can rely on the changed duty treatment for sourcing, pricing and customs clearance while the Order stands.
