This Order (effective 19 May 2009) declares that certain cast‑iron coupling nuts — defined by two size limits (internal diameter ≤50 mm; outside flange ≤91 mm) and classified at tariff heading 7318.16.00 — are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It was made by a delegate of the Chief Executive Officer under s.269P and remains in force until revoked under ss.269SC/269SD (or a specified expiry). The change alters tariff treatment for importers and creates a classification/compliance requirement for customs officials and traders.
