This Tariff Concession Order (TCO 0936044) declares that a specific import — rotors with arms for a "gluten disintegrator" (tariff code 8479.90.00) — is a good to which Item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies. It was made under s.269P of the Customs Act 1901 and took effect 24 September 2009.
Mechanically, the order changes the tariff treatment for importers of those parts; the decision was made by a delegate of the CEO (Michael Perry) and the order remains in force until revoked under ss.269SC–269SD. Importers must use correct classification and documentation to access the concession.
