This Tariff Concession Order applies item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995 to nylon textured yarn (Tariff classification 5402.31.00) measuring not greater than 50 tex. It was declared under s 269P, takes effect from 30.09.2005 and remains in force until revoked under ss 269SC or 269SD. Mechanically, it changes which Schedule 4 item governs imports of that specific yarn, so importers must ensure their goods match the description and classification; the instrument does not itself state the resulting duty treatment.
