In international ocean freight, the Booking Confirmation is one of the most important documents you receive after booking space with a carrier or freight forwarder. It is the basis for planning your cargo loading, moving containers to the port, clearing customs, and preparing your export paperwork.
Yet many companies only skim the Booking Confirmation and overlook critical details such as the Closing Time, CY Cut-off, ETD, ETA, or container type. That oversight can lead to late container delivery, extra charges, and even a Roll Over (missed sailing).
So what is a Booking Confirmation? And how do you read and verify it correctly? This article walks you through it step by step.
What Is a Booking Confirmation?
A Booking Confirmation is the document issued by a carrier or freight forwarder confirming that they have accepted a customer's booking request.
A Booking Confirmation typically shows the vessel details, the shipping route, the port of loading, the port of discharge, the container type, the cut-off times, the number of containers, the booking number, and more. It is the reference point from which your entire export plan takes shape.

Why You Need to Check Your Booking Confirmation
Reviewing your Booking Confirmation carefully helps your business:
- Confirm you have booked the correct route.
- Have your containers ready on time.
- Avoid delivering cargo to the wrong port.
- Stay ahead on customs clearance.
- Reduce the risk of storage charges.
- Minimize the chance of a roll over.
Key Information on a Booking Confirmation
1. Booking Number
This is the booking reference issued by the carrier. The booking number is used to:
- Look up shipment details.
- Prepare the Shipping Instruction.
- Track shipment progress.
- Communicate with the carrier or forwarder.
Always verify the exact booking number to avoid mixing up shipments.
2. Shipper and Consignee
The booking will show:
- Shipper: the party sending the goods.
- Consignee: the party receiving the goods.
Be sure to check:
- Company name.
- Address.
- Contact details.
An incorrect company name can affect how the bill of lading is issued.
3. POL (Port of Loading)
The POL is the port of loading - for example, Cat Lai, Cai Mep, or Hai Phong. Confirm the exact port where your containers must be delivered.
4. POD (Port of Discharge)
The POD is the port of discharge. Getting the destination port wrong can mean very costly amendment fees.
5. Place of Delivery
Some shipments also specify an ICD, an inland depot, or a final delivery point. Check whether the cargo is delivered at the port or moved further inland.

6. Vessel / Voyage
This covers the vessel name and the voyage number.
For example:
- EVER ACE V.152E.
- CMA CGM XXX.
This information is essential for tracking the vessel's schedule.
7. ETD (Estimated Time of Departure)
This is the estimated departure date. The ETD directly affects your loading plan, customs declaration, document preparation, and contractual delivery commitments.
8. ETA (Estimated Time of Arrival)
The ETA is the estimated date the vessel arrives at the destination port. Buyers usually rely on the ETA to prepare to receive the goods.
9. CY Cut-off
This is the final deadline for your container to enter the port. Deliver after this time and your container may not be loaded, may be rolled over, or may be pushed to a later sailing.
10. SI Cut-off (Shipping Instruction Cut-off)
This is the deadline for submitting the Shipping Instruction to the carrier. Submit late and:
- The bill of lading may be issued late.
- Amending documents becomes difficult.
- International payment can be affected.
11. VGM Cut-off
The VGM (Verified Gross Mass) is the confirmed total weight of the container. You must submit the VGM on time. Otherwise:
- The container may not be loaded.
- Amendment charges may apply.

12. Container Type
The booking specifies the exact type: 20GP, 40GP, 40HC, Reefer, Open Top, Flat Rack, and so on. Verify that it matches the container type you ordered.
13. Quantity
This covers:
- The number of containers.
- The container type.
For example:
- 01 x 20GP.
- 02 x 40HC.
14. Commodity
This is the cargo description. Check that it matches both the actual goods and your contract.
15. Freight Term
The booking usually states Freight Prepaid or Freight Collect. This must align with the payment terms and Incoterms® in your international sales contract.
Key Deadlines to Keep in Mind
A Booking Confirmation carries several deadlines, and you should pay particular attention to the CY Cut-off, SI Cut-off, VGM Cut-off, ETD, and ETA. Missing any one of them can delay your export.

Common Mistakes When Checking a Booking
Companies frequently run into errors such as the wrong port of loading or discharge, the wrong container type, overlooking the CY Cut-off, missing the SI deadline, failing to declare the VGM, an incorrect shipper or consignee name, or not checking for schedule changes. These slip-ups can trigger extra costs and disrupt delivery timelines.
Best Practices for Checking a Booking Confirmation
To reduce risk, we recommend that you:
- Read the entire booking as soon as you receive it.
- Cross-check it against your sales contract.
- Verify the details with your freight forwarder.
- Monitor the vessel schedule ahead of the ETD.
- File the booking together with your export documents.
- Request amendments promptly if you spot an error.
The Role of a Freight Forwarder
A professional freight forwarder helps you check the booking, track the vessel schedule, remind you of cut-off deadlines, amend the booking when needed, handle roll-over situations, and coordinate with the carrier whenever changes arise. All of this lowers your risk and keeps deliveries on schedule.

Conclusion
The Booking Confirmation confirms your booking details and anchors your shipping plan. Reading it carefully - the booking number, ETD, ETA, POL, POD, CY Cut-off, SI Cut-off, VGM Cut-off, and container type - helps you avoid mistakes, prevent extra charges, and lower the risk of a roll over.
