Chapter 90 classification notes

Many items duty-free under ITA. Medical devices require regulatory approval (FDA 510(k), CE marking, TGA). Professional equipment may require ATA Carnet for temporary import. High-value items attract customs scrutiny.

Frequent misclassification in this chapter

Digital cameras that are primarily smartphones classify under 8517 (Ch. 85), not 9006. Medical device accessories may classify separately from the main device.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
