Weight and volume
Air freight often uses chargeable weight, not actual kilograms alone. Large but light cartons can still price high by volume.
Use this Vietnam logistics quote desk to screen sea, air, express, customs-document, warehousing and door-to-door routes before you book. Enter weight, carton size, Vietnam destination or export route, and cargo details to get a working estimate. For bulky cargo or restricted goods, contact our logistics team for a manual review.

Enter weight, carton size, destination and cargo type. The tool returns a first-pass route screen, then VOSA confirms the exact lane when the cargo is ready.
Enter weight, carton size, destination, and cargo attributes to compare route options before requesting a final quote.
VOSA screens the full route: pickup, packing, landed-cost logic, customs-document needs, and final delivery handoff.
A quote is useful only when it reflects how carriers actually price freight. The largest variables are chargeable weight, restrictions, destination and service speed.
Air freight often uses chargeable weight, not actual kilograms alone. Large but light cartons can still price high by volume.
Air cost changes sharply when cartons are oversized, the lane is urgent, or cargo needs a special line for batteries, liquids or branded goods.
Remote areas, document handling, door delivery, warehouse handoff and export handoff all affect final cost.
The estimate removes obviously wrong lanes quickly. VOSA still checks carton density, shipment count and real delivery windows before suggesting a booking path.
| Shipment snapshot | Route read | VOSA checks next |
|---|---|---|
| 4 cartons, 21kg, 0.12 CBM, needed in 5 days | Screen air freight first | Verify chargeable weight and whether the standard lane can handle it. |
| 28 cartons, 310kg, 1.9 CBM, target 22-30 days | Screen sea freight first | Check whether consolidation and sea timing protect margin better. |
| 2 cargo lots, special labels, near battery category, under 10 days | Manual quote required | Review preparation, restrictions and whether a special lane is needed. |
Using reference logic from Freightos freight calculator and chargeable weight, volumetric weight and route urgency are two common reasons estimates change.
The estimator helps compare routes quickly, but some shipments need VOSA logistics review before final confirmation.
If you need full logistics support, start from the VOSA service desk while cargo data is still unclear; then use the quote desk after weight, carton size, destination and restrictions are known.
Request manual quoteIt is most useful when carton size, weight, destination and cargo simplicity are already known. For simple cargo under about 5 cartons with no restrictions, VOSA treats it as a strong first screen.
Because carriers may price by volumetric weight instead of actual kilograms. An 18kg shipment can rate heavier if cartons are too large.
Yes. If documents, repacking, consolidation, destination handling or special-cargo review is needed, VOSA should review it manually.
The main limitation of any shipping cost estimator is that it cannot see every operational trade-off on its own. If your cargo needs extra prep, comes from 2 or more handoff points, or must hit a strict warehouse cut-off in under 10 days, our team treats the estimate as a first-pass screen rather than the final booking answer.
