Import Duty & GST Estimate

Estimate border taxes without hiding missing costs

Enter the customs value in NZD, international freight and insurance, and a duty rate you have confirmed for the goods. A default of zero is an input assumption, not a tariff classification.

Worked example

For $1,500 of goods and $100 freight at 0% duty, import GST is $240. If the confirmed duty rate were 5%, duty would be $75 and GST would be $251.25, giving $326.25 in these taxes.

How the result is built

Duty is applied to goods value. For the supported collected-tax scenario, GST is applied to goods plus freight/insurance plus duty.

Before you use the number

Customs/MPI levies, broker charges, excise and exchange-rate questions are excluded. Low-value goods may have supplier-collected GST even when this tool shows no border collection.
