This Tariff Concession Order applies a Schedule 4 tariff item to a narrow class of imported goods: plastic base plates with raised studs, classified at tariff heading 9503.00.70, effective from 23 October 2008 until revoked.
Mechanically, the order changes the customs tariff treatment that applies to importers of those parts (bringing them within the Schedule 4 item named in Column 2); the decision is made by a delegate of the Chief Executive Officer under s.269P and can be revoked under ss.269SC/269SD, so importers must correctly classify goods and manage revocation risk.
