What is VGM?

What is VGM?

VGM (Verified Gross Mass) is the verified total weight of a shipping container, including:

• Cargo weight
• Packaging and dunnage materials
• The tare weight of the empty container

It is a mandatory document in international maritime transport to ensure safety at sea.

According to the International Convention for the Safety of Life at Sea (SOLAS), the shipper or consignor must provide an accurate VGM before the container is loaded onto the vessel. This helps prevent incorrect weight declarations, avoid vessel imbalance, and protect the safety of crew members, cargo, and the vessel itself.

Why Businesses Should Care About VGM?

• Compliance with international law: Avoid cargo being refused for loading, shipment delays, or penalties.
• Ensure transport safety: Proper cargo distribution reduces the risk of maritime accidents.
• Prevent additional costs: Avoid reweighing fees, storage charges, or extra handling costs.
• Enhance business reputation: Maintain good relationships with carriers and international partners.

How to Determine VGM

How to Determine VGM

Businesses can determine Verified Gross Mass using one of the two SOLAS-approved methods:

1. Weighing the entire loaded container

• Weigh the packed container at a certified weighbridge.
• Highly accurate and quick to perform.

2. Calculating the sum of individual items plus container tare weight

• Weigh the cargo, packaging, and dunnage separately.
• Add the tare weight (printed on the container’s exterior).

Note: If the weight changes after the VGM has been declared, businesses must update and submit the revised VGM to the carrier before the cut-off deadline to avoid cargo rejection.
