Tariff Concession Order 0509821 declares that imported woven polypropylene lanyards (tariff code 6307.90.99) are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 26 July 2005. The Order was made by a delegate of the CEO under s.269P of the Customs Act 1901 and remains in force until revoked under ss.269SC or 269SD. Mechanically, it changes the tariff treatment of those imports, affecting importers' duty liability and related compliance (classification and documentation).
