Australia has no FTA with South Africa, so MFN duty rates apply to all Chapter 84 machinery imports; the most critical compliance obligation for this combination is confirming that any motor-driven or electrical plant meets ACMA RCM requirements and that used machinery is declared accurately to DAFF for mandatory biosecurity inspection on arrival.
Import tip
Request the manufacturer's technical datasheet and confirm the correct 8-digit HS tariff subheading with your broker before the shipment leaves origin — reclassification of machinery at the border (e.g. between 8479, 8428 or chapter 73/94) is a common ABF audit trigger and can delay clearance by days while also affecting whether your FTA certificate covers the correct tariff line.
Calculate the total landed cost for Chapter 84 goods from South Africa — duty, GST, IPC, and biosecurity included.
