This Tariff Concession Order applies Item 50 of Part III of Schedule 4 of the Customs Tariff Act 1995 to a specific piece of equipment described as “rotating levellers” (tariff classification 8428.90.00) used in a solid-waste fuel‑processing silo, effective 22 February 2011 until revoked. It changes the customs/tariff treatment for importers and manufacturers of that equipment and alters the compliance and payment obligations administered by the customs authority while the order remains in force.
