Importing goods into Singapore: duty and GST on the landed cost

Published April 22, 2026 · 3 min read

How import duty and 9% GST stack up on shipments into Singapore, with a worked landed-cost example.

The customs value

Duty is usually charged on the customs value of the goods, which in many countries includes the price paid plus shipping and insurance to the border. Some countries use the value at the point of export instead, so check the valuation basis that applies in Singapore.

Worked example

Here is the calculation with sample figures. Change any number in the Singapore Import Duty Calculator to run your own.

Duty rates depend on the product code

Every product has a tariff classification code, and the duty rate is set per code. Two similar products can carry very different rates. Trade agreements, quotas and anti-dumping measures can change the rate again, so the 5% used in the example below is only an illustration.

GST is charged on top of duty

Import GST in Singapore is normally charged on the customs value plus the duty, which means you pay tax on the duty itself. Registered businesses can often reclaim import GST as input tax, but the duty is a real cost.

Quick reference at 9%

Common amounts in Singapore, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.

How Singapore compares

Standard rates on file for other countries. A difference of a few points matters most on high-value purchases and on cross-border sales.

Using the calculator step by step

1. Open the Singapore Import Duty Calculator.
2. Type your figures into the numbered lines. Results update as you type.
3. Check the rate field. It starts at 9%; change it if a reduced rate, local surcharge or exemption applies to you.
