This Order (TC 0608075) states that certain imported "worm" wheels and parts (cone worm rims, cone worms, shafts) classified at tariff heading 8483.40.90 are to which the Part III item in Schedule 4 of the Customs Tariff Act 1995 applies. It takes effect from 8 May 2006 and remains until revoked under sections 269SC or 269SD. Mechanically, it alters the tariff treatment on import — importers are affected because the applicable duty treatment changes — and is made and revocable by a delegate of the CEO.
