How GST and duty work in Australia
For most imports, Australia applies GST at 10% on the customs value plus freight and insurance. Import duty varies by HS code and can be reduced with the correct documentation and trade agreements.
Landed cost formula (simple)
Landed Cost = Customs Value + Freight + Insurance + Duty + GST + Local Charges
Use Wharvex’s calculators to estimate each component:
Common reasons costs change
- •Incorrect HS code classification
- •Missing certificate of origin for duty preference
- •Quarantine treatment or inspection charges
- •Port storage, demurrage, or detention fees
When to use DDP
If you want all taxes, clearance, and delivery bundled into one rate, DDP can reduce internal admin and surprise charges.
