This Tariff Concession Order, made under section 269P of the Customs Act 1901 by a delegate, declares a specific programmable stone‑cutting line (tariff classification 8464.10.00 with the listed components) to which Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 19 September 2007.
Mechanically, the order lets importers of that exact machine claim the Schedule 4 concession (reducing or exempting customs duty under item 50). The concession remains until revoked under sections 269SC or 269SD or any date shown, so importers must ensure imported goods match the description to qualify.
