Import from Thailand to Singapore: GST, Permits and TradeNet (2026)
Singapore is close to a free port. Most goods carry no customs duty at all, which surprises buyers who arrive expecting a tariff exercise. The work sits elsewhere: permits, GST cash flow and controlled-goods clearances.
What you actually pay
| Charge | Rate | Notes |
|---|---|---|
| Customs duty | 0% on most goods | Duty applies only to intoxicating liquors, tobacco, motor vehicles and petroleum products |
| GST | 9% | On CIF value plus duty, at import |
| TradeNet permit | Small per-declaration fee | Filed by your declaring agent |
Because duty is zero on almost everything from Thailand, an ATIGA Form D is often unnecessary for Singapore consumption. It becomes essential again the moment the goods are re-exported to another ASEAN market.
The permit layer
Every import needs an IN permit filed through TradeNet, Singapore's single window. To file, the importer must be registered with ACRA, activated for customs accounts, and - for dutiable or controlled goods - hold the right inter-bank GIRO or security arrangement.
Steps for a first shipment:
- Register the entity and activate a Customs Account
- Appoint a declaring agent, or apply for your own TradeNet access
- Check whether the HS code is controlled by a Competent Authority
- Obtain any Competent Authority approval before the goods sail
- File the IN permit before arrival and present it with the transport document
Controlled goods that catch Thai shipments
| Category | Authority | Typical requirement |
|---|---|---|
| Processed food, meat, seafood, produce | SFA | Trader licence, facility listing, consignment approval |
| Medical devices, supplements, cosmetics | HSA | Product registration or notification before import |
| Telecom and radio equipment | IMDA | Equipment registration |
| Electrical appliances and adaptors | Enterprise Singapore CPS | Safety Mark for controlled goods |
| Chemicals, batteries | NEA | Hazardous substance licence where scheduled |
Food and medical categories account for most delays we see on Thailand-Singapore lanes. Register the product before the container leaves Laem Chabang, not after it arrives at PSA.
GST cash flow - the part finance cares about
At 9%, import GST on a large regional buying programme is real working capital. Three reliefs matter:
- Major Exporter Scheme (MES): suspends GST at import for qualifying traders who mainly re-export. This is the single most valuable scheme for a regional HQ holding stock in Singapore.
- Free Trade Zones: goods stored in an FTZ have GST and duty suspended until they enter local circulation. Re-export straight from the FTZ and neither is ever paid.
- Import GST deferment schemes for approved businesses, shifting the payment to the GST return.
Input GST on genuine imports for business use is recoverable, so for a GST-registered importer the cost is timing, not tax.
Freight and transit from Thailand
| Mode | Typical transit | Comment |
|---|---|---|
| Sea LCL/FCL, Laem Chabang to PSA | 3-5 days sailing, 7-10 days door to door | Cheapest, ample sailings |
| Cross-border truck via Malaysia | 4-6 days door to door | Good for urgent or oversized cargo |
| Air, BKK to SIN | 1-2 days | Sensible for samples, medical and electronics |
Singapore's clearance speed means the port is almost never your bottleneck. Thai-side documentation quality is.
If Singapore is a transit point, not the market
Keep the goods inside an FTZ, avoid any processing beyond unloading, reloading and preservation, and make sure the origin certificate for the onward destination carries the third-party invoicing declaration. Repacking in a local warehouse is the classic way a regional HQ accidentally destroys an ATIGA claim in the destination country.
How we work
We handle the Thai side end to end - factory selection, pre-production checks, inspection and export documentation - and quote a landed cost to Singapore or direct to your regional destination. You approve the number before production; our margin is inside it.

FAQ
Is there import duty on Thai goods entering Singapore? No for the vast majority of products. Duty is limited to liquor, tobacco, motor vehicles and petroleum products.
Do I need an ATIGA Form D for Singapore? Usually not, because duty is already zero. You do need one if the goods will be re-exported to another ASEAN market and preference will be claimed there.
How much is import GST and can I recover it? 9% on CIF plus duty. A GST-registered business recovers it as input tax; MES or FTZ storage avoids paying it at the border at all.
What is TradeNet? Singapore's single-window system for import, export and transhipment permits. Every consignment needs a permit filed before clearance.
Which Thai products need pre-approval? Food and beverage, meat and seafood, health supplements, cosmetics, medical devices, telecom equipment and controlled electrical goods. Register with the relevant authority before shipping.
