This Tariff Concession Order, made under s.269P of the Customs Act 1901, declares that parts described as blades for wind‑powered generators (tariff code 8503.00.00) are subject to item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 01.03.2010 until revoked. Mechanically, it applies the Schedule 4 concession to those imported goods. It affects importers and supply chains for wind‑turbine blades (who may face different customs charges under item 50); a CEO delegate issued it and revocation is governed by ss.269SC–269SD.
