## How Singapore import charges work

| Value of the goods | What you pay |
| --- | --- |
| S$400 or less, by air or post | 9% GST charged by the overseas seller or marketplace at checkout (registered under the overseas vendor regime). |
| Over S$400, or by sea | 9% GST on the cost of the goods plus insurance and freight, collected at import, usually through the courier. |

Singapore charges customs duty only on liquor, tobacco, motor vehicles and petroleum, so clothes, electronics and most other goods pay no duty.
