Vietnam–Cambodia Transport: Transit by Truck, Sea and Air (2026)

Because direct capacity at Cambodian seaports remains limited, routing cargo through Vietnamese gateways is still the most efficient way to serve Cambodia in regional supply chains. Doing it well requires synchronized customs planning on both sides of the border. AlphaTrans operates an asset-backed transit network across all major bilateral border gates — with our own fleet of 65 container trucks, a transit customs clearance team, and offices at both the Bavet border and Phnom Penh.

1. Multi-Modal Routing Matrix

1.1 Transit cargo via Vietnam (cross-border integration)

Service type	Routing	Handling & customs legs	Destination hubs
LCL / Air	International origin → VN CFS/airport → Cambodia door	1) Transit clearance at HCMC CFS (Cat Lai) or SGN Airport 2) Import clearance at Bavet 3) Final delivery to door	Bavet SEZs (Taiseng 1 & 2, Manhattan, Shangdong, Giga…)
FCL (Import)	International origin → VN seaports → Cambodia	Option A (road): Cat Lai → Bavet SEZ. Option B (waterway): Cat Lai → Phnom Penh Port / PPSEZ via the sea–river channel. Includes port transit customs + cross-border clearance	Phnom Penh PPSEZ, Bavet SEZ, all provinces
FCL (Export)	Cambodia → VN seaports → global destinations	1) Export clearance at Bavet 2) Import transit clearance at the Vietnam entry gate 3) Port handling and ocean staging at Vietnamese terminals	Factory to Cat Lai / Cai Mep

1.2 Exporting directly from Vietnam to Cambodia

Sea freight — direct ocean freight bookings from major Vietnamese ports to Phnom Penh Port and Sihanoukville Autonomous Port (PAS), FCL or LCL.
Cross-border road freight — direct trucking from Vietnamese factories to all Cambodian provinces under EXW, FOB, DAP or DDP.

2. Required Documents and the Critical B/L Clause

To avoid border delays, documentation must strictly follow cross-border transport regulations. AlphaTrans manages and verifies the full folder:

OLA (independent transport declaration) and transit contract & shipping manifest
Commercial Invoice & Packing List; Letter of Authorization (LoA)
Detailed list of goods in transit (Form No. 09 under Circular 39)
Transit Bill of Lading & ocean line bookings

Critical B/L clause for transit cargo — the ocean B/L must explicitly read:

“CARGO TRANSIT VIA HO CHI MINH CITY SEA/AIRPORT – VIETNAM TO CAMBODIA BY TRUCK. CONSIGNEE WILL BE RESPONSIBLE FOR ON-CARRIAGE FROM HO CHI MINH CITY TO CAMBODIA. DESTINATION: CAMBODIA.”

3. Step-by-Step Handling and Transit Timelines

3.1 OLA transit procedure via HCMC ports (export direction)

Secure the ocean booking and position assets.
Pick up empty containers (FCL) and dispatch to the customer’s facility for stuffing.
Execute export customs at the Cambodian border station (Bavet).
Open the independent transport declaration (OLA) at the Vietnamese entry gate (Moc Bai).
Complete border inspections; apply customs seals (FCL) or official stamps (LCL).
Haul cargo from the border gate to the export terminal (Cat Lai / Cai Mep).
Liquidate and close the OLA declaration with Vietnam Customs at the port of departure.

3.2 Transit time commitments

Cambodia → global markets via Vietnam: 1–2 working days from completion of stuffing.
Global inbound via Vietnamese ports → Cambodia: 3–5 working days from vessel ETA at Cat Lai, Cai Mep or SGN.
Premium lumpsum service: 1 working day from cargo receipt at our hubs.

Actual intervals fluctuate with seasonal peaks and border congestion; the figures above are our standard operating baselines.

7. Frequently Asked Questions (FAQ)

Q1: When should I choose the sea/river barge route over cross-border trucking? Three situations: (1) heavy industrial cargo exceeding road axle-load limits; (2) high-volume batches (5–10+ TEUs) where budget beats speed — barge solutions typically cut logistics cost by 30–40% versus dedicated trucking; (3) peak seasons when land checkpoints such as Moc Bai/Bavet face severe congestion.

Q2: How does AlphaTrans handle CDC tax-exempt projects in Cambodia? Companies under Council for the Development of Cambodia (CDC) incentives qualify for 0% duty on approved materials and machinery. We review your CDC Master List before loading, match descriptions/HS codes/quantities across the B/L and invoice, and lodge files into Cambodia’s ASYCUDA system so no duty re-assessment occurs on arrival.

Q3: Can transit cargo from Europe/China pass through Vietnam without paying Vietnamese taxes? Yes. Under the OLA framework, international cargo arriving at Cai Mep or Cat Lai never enters the Vietnamese domestic market: the container stays under customs bond, transit documents are processed within 24 hours of discharge, and the cargo moves by bonded truck or barge to Phnom Penh without triggering Vietnamese import duty or VAT.
