The weight of the goods and VGM solve different tasks
The team has agreed on the invoice, but the terminal needs the verified gross mass of the entire loaded container.
If you send the weight of the grain without packaging and container instead, matching it with the invoice will not make the information correct.
According to IMO guidance, the shipper is responsible for providing the VGM in the sense of the applicable maritime transport documents.
The information is transmitted to the vessel representative and the terminal in advance for stowage planning.
VGM is a loading condition, but it is not a guarantee that the container will be loaded onto the selected voyage.
Let’s discuss VGM data and confirmation handover in your company
I can help you review VGM data and confirmation handover, connect documents and confirmations, and identify the participants and next steps.
We can also discuss similar difficulties and related foreign trade tasks in your company.
We will agree on the scope before work begins.
Agree on the method of confirmation and transfer
IMO describes two approaches: weighing the loaded container or determining the weight of all components with the addition of the container’s tare using a certified method approved by the competent authority of the packing state.
An arbitrary sum in a table does not replace such a method.
Before loading, find out who will organise the applicable procedure, who is authorised to sign and transfer the information, who will receive it, and in what format.
Clarify the deadline specifically for booking and the terminal.
A contract with a freight forwarder may allocate operations, but legal responsibility should not be derived solely from the internal job title.
VGM transfer register
This is an organisational control, not a formal document form.
| Stage | What to save | Control question |
|---|---|---|
| Preparation | Container ID and completeness | What actual loading is taken into account? |
| Weight confirmation | Document and applied method | Have the method requirements been met? |
| Signing | Authorised party | Who is responsible for the information? |
| Transfer | Recipient, date, and status | Were the data received via the required channel? |
| Change | New loading and decision | Is a repeat procedure needed? |
The ‘sent’ mark and receipt confirmation are different events.
Save both if the carrier’s system separates them.
Return the change for verification
A training situation: after receiving the weight document, two packages were added.
The coordinator records the change and passes the issue to the VGM responsible party.
The old value cannot continue to be used just because it has already been entered into the booking.
If there is a discrepancy with the commercial documents, first check the measurement boundary: VGM includes the entire loaded container.
In case of a real error, use the carrier and terminal correction procedure; do not create competing versions without cancelling the previous one.
Check the chain before the terminal deadline
For the manager, it is sufficient to see four confirmations: the procedure is defined, the information is prepared, the transfer has taken place, and there are no open changes.
Assign a backup contact in case of channel failure or the absence of the main employee.
For initial numbers, use net, packaging, and tare weight reconciliation.
For deadlines, use a separate booking calendar.
Do not substitute the readiness of the VGM for other conditions for accepting the container and loading it onto the vessel.
