This order declares a specific type of valve — motor‑actuated, two‑stage globe pressure‑reducing valves (tariff heading 8481.10.00) — as eligible for Schedule 4 tariff concession item 50 from 6 April 2011, until revoked (made under s.269P; revocation under ss.269SC/269SD). The practical effect is to lower the customs duty payable by importers of those valves; the delegate of the CEO (Paul Mercer) issued the order. Importers must correctly classify goods to claim the concession and face regulatory and compliance risk if the order is later revoked.
