VGM in the shipping/logistics

VGM (Verified Gross Mass) refers to the total weight of a packed shipping container, including the cargo, packaging, and the container itself. It’s a legal requirement under the SOLAS (Safety of Life at Sea) Convention, which has been in effect since July 1, 2016. The main goal is to ensure safe stowage and handling of containers on ships.

Here’s what you need to know:

1️⃣ Why VGM Matters

• Overweight or incorrectly weighed containers can cause accidents, damage cargo, or lead to ship instability.
• Accurate VGM helps terminal operators, shipping lines, and port authorities plan safe loading and avoid fines.

2️⃣ Who Must Provide It

• The shipper of the cargo (the party named on the Bill of Lading) is legally responsible for providing the VGM to the carrier before the container is loaded onto the vessel.

3️⃣ How to Determine VGM

There are two approved methods under SOLAS:

Method 1 – Weighing the packed container (most common)

• Use a calibrated weighbridge or container scale.
• Includes the weight of the cargo, packaging, dunnage, and container.

Method 2 – Calculating from package weights

• Sum up the gross weight of all packages + tare weight of the container.
• Must be accurate and verifiable.
• Usually used when weighing the whole container is impractical.

4️⃣ When to Submit VGM

• Must be submitted to the shipping line or carrier before the vessel’s cargo cut-off.
• Typically provided via electronic submission or standard forms.

5️⃣ Consequences of Not Providing VGM

• Container may not be loaded onto the vessel.
• Potential delays, fines, or extra costs.
• Safety risks increase significantly.

💡 Tip for Shippers: Always double-check the tare weight (empty container weight) on the container’s door—it’s essential if using Method 2.
