Declares that imports classified at tariff heading 8431.49.90 ("handlers, railway sleeper") are subject to the tariff treatment in Part III, Schedule 4 item 50, effective 31 January 2007. The Order was made by a delegate under s.269P of the Customs Act and continues until revoked under ss.269SC–269SD.
Who pays and what changes: importers of these goods must claim the Schedule 4 item to obtain its tariff treatment, so government revenue and importer costs turn on that Schedule entry. The Order is revocable, creating ongoing administrative discretion and a need for correct tariff classification and supporting documentation.
