This Tariff Concession Order declares that certain gate valves (water-cooled body, with or without actuators) under tariff heading 8481.80.90 are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 29 November 2011. It changes import duty treatment for those valves and therefore affects importers, local buyers and competitors by altering costs and compliance obligations. The declaration was made by a delegate under s.269P and can be revoked under ss.269SC or 269SD.
