The Verified Gross Mass (VGM) of a container – its total weight including cargo, packaging, and the container’s tare – is more than just a number. It’s a safety-critical requirement governed by the SOLAS (Safety of Life at Sea) Convention, mandatory for all containers loaded on ships in international traffic since July 1, 2016.

What Is VGM and Why Does It Matter?

Shippers are responsible for submitting the VGM to the shipping line and terminal before loading, using one of two approved methods:
– Weighing the packed container using certified equipment
– Calculating total weight by adding cargo, packaging, and tare weight

An accurate VGM ensures proper load distribution, vessel stability, and safe crane operations during loading and unloading. Inaccurate or late declarations can result in:
– Container stacking failures
– Damage to ship structures and port equipment
– Accidents, delays, or denied loading
– Fines and reputational damage

Recent Incidents That Reinforced the Need for VGM

Despite regulations, VGM remains a weak point in shipping compliance. Some major incidents tied to incorrect or absent weight declarations include:

– Fremantle Highway (2023): A fire aboard this car carrier raised safety concerns related to misdeclared cargo and improper weight distribution.

– Maersk Essen (2021): More than 750 containers fell overboard during heavy rolling in the Pacific. Investigators cited possible weight declaration errors as a contributing factor.

These incidents underscore how critical proper VGM practices are - not just for compliance, but for human safety and global trade continuity.

Best Practices for Shippers and Forwarders

– Use calibrated weighing equipment and keep certification up to date
– Train operations staff on documentation accuracy and submission timing
– Double-check weights before the container is released for transport
– Align with carriers and terminals on cut-off times and preferred formats
– Build internal SOPs that include VGM checks as part of every export flow

Conclusion

VGM isn’t just another field to fill out – it’s a frontline defense against costly and dangerous consequences. By maintaining strict weight declaration standards, shippers and freight forwarders help ensure a safer, more reliable maritime supply chain.
