This Tariff Concession Order (TCO 0922340) declares that specific resin‑bonded grinding wheels (tariff classification 6804.22.00) are eligible for the Schedule 4 Part III concession item 50 of the Customs Tariff Act 1995, effective 30 June 2009 until revoked (authority: s.269P Customs Act 1901; revocation under ss.269SC/269SD). The change lowers import duty for importers of those wheels (reducing their landed cost) and therefore shifts competitive pressure onto domestic suppliers; the declaration was made by a delegated officer (Wendy Knowles).
