Why is bunker cost calculated in the TCTO Estimate?

In the Veson IMOS Platform, if the TCTO estimates indicate bunker costs, it is essential to first verify the itinerary sequence of the estimate. The port itinerary sequence must align with the TCI Contract.

Once the delivery port specified in the TCI Contract is designated as the first port within the itinerary sequence of the estimate, the bunker expenses will be automatically excluded from the TCTO estimate.
