Verified Gross Mass

Last updated: February 11, 2026

Verified Gross Mass (VGM) refers to the total confirmed weight of a packed shipping container, including the cargo, packaging, dunnage, and the container’s tare weight. Under international maritime safety regulations, this weight must be accurately declared before a container is loaded onto a vessel. The requirement was introduced to improve ship stability and prevent accidents caused by misdeclared container weights.

VGM must be obtained using approved methods, such as weighing the packed container on a certified scale or calculating the weight of all contents and adding the container’s tare weight. The verified figure is then submitted to the carrier and terminal before the vessel’s cut-off time. Without a valid VGM, containers may be refused for loading, causing delays and additional costs.

The VGM rule enhances safety across the shipping industry by ensuring vessels are loaded correctly. Accurate weight data helps carriers plan stowage, balance ships properly, and reduce risks during sea transport. It also supports compliance with port and terminal safety procedures.

Overall, Verified Gross Mass is a critical requirement in container shipping. It improves operational safety, reduces incidents at sea, and ensures transparency in cargo weight declaration. Proper VGM compliance helps keep global shipping efficient and secure.
