Verified Gross Mass


The International Maritime Organisation (IMO) has adopted amendments to the Safety of Life At Sea (SOLAS) convention, which require shipper’s to declare Verified Gross Mass (VGM) of all containers before loading on board a vessel. Verified gross mass means that container weights cannot be estimated. The regulation is compulsory and applies worldwide as of 1st July 2016.

The responsibility for obtaining and providing the VGM (Verified Gross Mass) lies with the shippers.
There are 2 methods by which shipper may obtain the VGM of a packed container:

Method 1 : Weighing of the packed container
Method 2 : Weighing all packages and cargo items including pallets and dunnage and adding container tare weight.

Please note in some countries national authorities require “ Method 2” shippers to register for auditing purposes.

This requirement is in place in the UK as all “Method 2” shippers must register with the UK Maritime and Coastguard Agency (MCA).
