Air Freight from China to Tuas
China → Tuas · via SIN air / Tuas Port sea · clearance by Singapore Customs

We move air freight cargo from South China into Tuas through SIN air / Tuas Port sea. Tuas is the new mega-port district and heavy industry zone, which shapes the kind of cargo that moves on this lane and how it should be packed.
The clearing authority is Singapore Customs. Historical dwell on this gateway is around 1–3 days, and it lengthens in Sep–Nov.
How this lane actually runs
Singapore is a free port and the cleanest customs environment in the region — most cargo clears in under a day. It is also the natural consolidation point for onward moves into Indonesia, Malaysia and the wider ASEAN market, so many buyers use a Singapore DDP delivery as a staging step rather than a final destination.

Duty, tax and clearance into Tuas
Imports into Singapore are cleared by Singapore Customs. The headline position is: GST 9%; import duty 0% on almost everything except liquor, tobacco, petroleum and motor vehicles. The de-minimis threshold is GST applies to low-value goods via the Overseas Vendor Registration regime.
Conformity is the part most first-time importers underestimate: IMDA registration for radio equipment; Safety Mark for controlled electrical goods; HSA license for health products. Getting this wrong is expensive because it usually cannot be fixed after the cargo has landed.
Restrictions and known friction points for Singapore: Chewing gum, e-cigarettes and vaping devices are prohibited outright. Telecommunication and radio devices need IMDA equipment registration. GST is charged on the full landed value with no practical de-minimis for commercial cargo.

Before you book: Tuas checklist
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Plan around the China-side windows too: Chinese New Year and Golden Week both compress capacity on the Singapore lane.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- Use ISPM-15 treated pallets. Untreated wood is the most common reason otherwise-clean cargo gets held.
- Check the de-minimis position (GST applies to low-value goods via the Overseas Vendor Registration regime) against your invoice value before you decide how to split the shipment.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
Frequently asked questions
How long does shipping from China to Tuas take?
China to the Singapore gateway is 2–4 business days. On top of that, allow 1–3 days of clearance with Singapore Customs and a same-day inland leg to Tuas.
What duty and tax will I pay importing into Tuas?
Singapore Customs applies: GST 9%; import duty 0% on almost everything except liquor, tobacco, petroleum and motor vehicles. The de-minimis position is GST applies to low-value goods via the Overseas Vendor Registration regime. Under a DDP arrangement these are pre-paid, so nothing is collected on arrival in Tuas.
Is sea freight cheaper than air freight into Tuas?
Per kilo, yes — usually by a wide margin. The trade-off is time: 4–7 calendar days by sea versus 2–4 business days by air to the Singapore gateway, before clearance and the same-day inland leg. The crossover point is normally somewhere between 100 and 300 kg depending on the density of your cargo.
How is the chargeable weight calculated for Tuas?
We compare actual gross weight against volumetric weight — length × width × height in centimeters divided by 6000 for air — and bill the greater of the two, rounded up to the next kilogram. Light, bulky cargo is almost always billed on volume.
Can you deliver door-to-door in Tuas?
Yes. Delivery to a Tuas address is quoted as one figure covering freight, duty and tax owed to Singapore Customs, and the same-day inland leg. Confirm whether your consignee wants the goods at a warehouse, a marketplace fulfillment center or a shop front, because the last-mile requirement differs.
What certification do I need for Singapore?
For regulated goods, plan for: IMDA registration for radio equipment; Safety Mark for controlled electrical goods; HSA license for health products. Missing conformity paperwork is the single most common cause of a hold, and in most cases it cannot be remedied once the cargo has arrived.

Checking the Singapore duty position yourself
Every duty and tax figure quoted on this page is our working estimate for planning, not a ruling. The binding rate for your consignment is whatever Singapore Customs applies against your declared HS code on the day of entry, and their published guidance is the source to check before you commit stock.
Most landed-cost surprises trace back to classification rather than freight. the WCO Harmonized System defines the heading structure every customs administration builds on, and ITC Market Access Map will show you the duty a given heading attracts in this destination.
On the air side, anything with a cell or a battery in it, plus liquids, powders, magnets and aerosols, is governed by the IATA Dangerous Goods Regulations. Those articles are not refused outright, but they need to be declared at booking so the shipment is built correctly — declaring them late is the single most common cause of an air consignment being offloaded.
If this is your first shipment into Singapore, the Singapore Country Commercial Guide covers the practical import environment in more depth than a rate page reasonably can, and it is written by a party with no stake in your booking.
