Please find an interesting explanation concerning VGM & Booked weight!
What is Verified Gross Mass (VGM)?
Verified Gross Mass is the shipper declared total gross mass of a packed container as obtained by one of the methods described below. This Verified Gross Weight must include all packages and cargo items, all additional loading equipment (e.g. packing materials) and the container tare weight. Please refer to Chapter 2.1 of the SOLAS guideline. VGM should not be confused with the weight declared when a booking is made nor should it be confused with the weight a shipper declares on the Bill of Lading sent via shipping instructions.
Does this mean the Verified Gross Mass weight (VGM) can be different than the booked weight or the Bill of Lading weight?
Yes. For many shippers the VGM may be different than the weight presented to carriers when cargo is originally booked and what they may list on the BOL. The weight declared on the Bill of Lading is most commonly the cargo gross weight and because of that fact it must differ from the verified gross mass (VGM) weight by definition. The intent of obtaining a VGM from the shipper per SOLAS guideline is for operational purposes. The BOL weight is commercial in nature and may be be different than the VGM depending on the shipper. Currently, there is no guiding information on what role the VGM will play as it pertains to documentation. At this time, there is no scenario where we will be required to report a shipper’s VGM submission to any authority unless this becomes a requirement of national legislation in the exporting country of origin. VGM is an internal data point and the shipping line will not be validating the VGM against the Bill of Lading weight, nor will we be printing the submitted VGM on the Bill of Lading.
