The International Maritime Organization has amended
the Safety of Life at Sea Convention (SOLAS) to require that shippers
submit the verified weight of a packed container (the “verified
gross mass" or VGM) before the container can be loaded onto a
ship for export.
VGM of a container must be weighed, verified and
correctly declared prior to vessel loading
In a nutshell, VGM =
Cargo weight + Packing material weight + Container Tare Weight
These new container weight verification
requirements become effective
July 1, 2016and apply globally.
There are two acceptable methods for weighing the
1. Weighing the container after it has been packed
2. Weighing all cargo and contents of the container
and then adding the container’s tare weight
Each country will be responsible for stating how
they will implement and enforce the rule.
