Sea Freight from China to Siem Reap, Cambodia — Transit, Duty and Clearance
China → Siem Reap · via REP air / Sihanoukville sea · clearance by General Department of Customs and Excise (GDCE)
For buyers shipping into Siem Reap, the practical question is not the ocean or flight time but what happens after arrival. Siem Reap is tourism economy with hospitality supply demand; cargo enters through REP air / Sihanoukville sea, and allow +2 days for the inland leg on top of clearance.
Clearance itself is handled by General Department of Customs and Excise (GDCE), and typical dwell at the gateway runs 3–7 days.
How this lane actually runs
Sihanoukville takes direct South China calls, while Phnom Penh is reachable by river barge from Cai Mep in Vietnam — often the cheaper option for LCL. Land trucking through the Bavet crossing from Ho Chi Minh City is a practical third route for urgent cargo that does not justify air.
| Sea gateways used | Sihanoukville Autonomous Port, Phnom Penh Autonomous Port (river) |
|---|---|
| Sea transit, China to gateway | 6–10 calendar days |
| Gateway serving Siem Reap | REP air / Sihanoukville sea |
| Inland leg to Siem Reap | +2 days from the gateway |
| Typical clearance / dwell | 3–7 days |
| Peak season to plan around | Sep–Nov |
What you will pay on arrival in Cambodia
General Department of Customs and Excise (GDCE) assesses duty and tax on cargo arriving for Siem Reap consignees. Current regime: VAT 10%; duty 7–35%, with ACFTA and RCEP preference on a Form E, with a de-minimis position of No practical de-minimis for commercial cargo.
Conformity is the part most first-time importers underestimate: CamControl inspection for regulated goods; Form E for duty preference. Getting this wrong is expensive because it usually cannot be fixed after the cargo has landed.
Restrictions and known friction points for Cambodia: Garment and footwear inputs move under specific duty-exemption schemes tied to the factory licence, so the consignee's status changes the landed cost materially. Used goods and secondhand electronics face restrictions.
What to sort out before the cargo leaves China
- Photograph carton markings and seal numbers before departure — it makes any claim far easier to settle.
- Get the conformity paperwork moving early: CamControl inspection for regulated goods; Form E for duty preference.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Ask for the HS code in writing from your supplier and verify the Cambodia duty rate against it yourself.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
- Budget for the inland leg: +2 days beyond gateway clearance to reach Siem Reap.

Is sea freight cheaper than air freight into Siem Reap?
Per kilo, yes — usually by a wide margin. The trade-off is time: 6–10 calendar days by sea versus 3–5 business days by air to the Cambodia gateway, before clearance and the +2 days inland leg. The crossover point is normally somewhere between 100 and 300 kg depending on the density of your cargo.
Can you deliver door-to-door in Siem Reap?
Yes. Delivery to a Siem Reap address is quoted as one figure covering freight, duty and tax owed to General Department of Customs and Excise (GDCE), and the +2 days inland leg. Confirm whether your consignee wants the goods at a warehouse, a marketplace fulfilment centre or a shop front, because the last-mile requirement differs.

Cargo for Siem Reap is routed via REP air / Sihanoukville sea. Sea gateways for Cambodia are Sihanoukville Autonomous Port, Phnom Penh Autonomous Port (river); air gateways are PNH (Phnom Penh), REP (Siem Reap). We pick whichever gives the shortest total door time for your address.
