This Order applies a Schedule 4 tariff concession (item 50) to steel pipes classified 7304.19.00, making those imports eligible for that concession from 24 January 2007 (declared under s269P, Customs Act 1901; revocable under ss269SC–269SD). Practically, importers gain reduced duty only if the goods match the written description; the CEO or a delegate (named) decides qualification, so correct classification, documentary proof and the administrative risk of revocation are the key implementation points.
