Verified Gross Mass (VGM)

What is Verified Gross Mass?

Verified Gross Mass (VGM) is a term used in the shipping industry to refer to the total weight of a packed container, including its contents and packaging materials. It is a crucial requirement mandated by the International Maritime Organization (IMO) under the Safety of Life at Sea (SOLAS) convention to enhance safety in maritime transportation. The VGM ensures that the weight of containers declared by shippers is accurate and helps prevent accidents, such as container overloading, which can pose risks to vessel stability and crew safety.

What is a Verified Gross Mass certificate?

A Verified Gross Mass Certificate is an official logistics document issued by the shipper or an authorized party, providing the accurate weight of a packed container as per the SOLAS requirements. The certificate contains essential information such as the container number, seal number, VGM, date of weighing, and the signature of the authorized person responsible for verifying the gross mass. It serves as proof of compliance with SOLAS regulations and must accompany the shipment documentation to facilitate smooth cargo handling and clearance at ports. Failure to provide a valid VGM certificate may result in delays or refusal of container loading onto vessels.\

How to determine Verified Gross Mass

Verified Gross Mass (VGM) can be determined through various methods. Firstly, the container can be directly weighed on a certified scale, providing an accurate total weight including cargo, packaging, and securing materials. Alternatively, items can be individually weighed and summed with the container's tare weight. Another approach involves calculating based on container dimensions and cargo density. Each method requires precision to ensure compliance with SOLAS regulations, preventing accidents and optimizing vessel stability. Choosing the appropriate method depends on factors like equipment availability, cargo characteristics, and regulatory requirements, ensuring safe and efficient maritime transport.
