How import tax works in Singapore
Importing goods into Singapore usually means two charges: customs duty on the value of the goods, then GST on the duty-inclusive amount.
Most goods are duty-free; 9% GST applies on imports above the relief threshold.
The calculator follows that order — duty first, then 9.00% GST on the customs value plus duty — to give your total landed cost.
Why the duty rate varies
Customs duty depends on the product's classification (HS code) and its country of origin, so there is no single rate. Trade agreements can reduce or remove it entirely.
Enter the specific duty rate for your product — your freight forwarder or the Singapore tariff schedule can provide it — for an accurate estimate.
Landed cost and thresholds
Landed cost is what the goods truly cost once duty, tax and shipping are included — essential for pricing if you resell. Many countries also waive charges below a low-value threshold.
This is a planning estimate. Confirm the duty rate, thresholds and any exemptions with Singapore customs or the Inland Revenue Authority of Singapore (iras.gov.sg).
