What is VGM in Shipping: A Complete Guide for Exporters

Quick Overview:

VGM (Verified Gross Mass) in shipping is the total verified weight of a packed shipping container before vessel loading. It includes the cargo weight, packaging materials, pallets or dunnage, and the container’s tare weight. Under SOLAS (Safety of Life at Sea) regulations introduced by the International Maritime Organization (IMO), VGM submission is mandatory for all packed export containers.

Here are the key things exporters should know about VGM:

The shipper on the Bill of Lading is responsible for VGM accuracy.
SOLAS allows two approved methods for VGM calculation.
Certified weighing equipment must be used for weight verification.
VGM must be submitted before the shipping line cut-off time.
An incorrect or late VGM submission can cause delays and extra charges.

Now that you have a quick understanding of VGM requirements, let’s understand how VGM works in shipping and why it is important for exporters.

What is VGM in Shipping?

VGM stands for Verified Gross Mass. It means the total verified weight of a packed shipping container before it is loaded onto a ship.

The VGM rule was introduced under the SOLAS (Safety of Life at Sea) regulation to improve safety in global shipping.

VGM includes four components:

Cargo weight: The actual goods being shipped
Packaging weight: Boxes, wrapping, strapping, etc.
Dunnage/pallet weight: Wooden pallets or any load-bearing material.
Container tare weight: the weight of the empty container itself.

Why is VGM Important in Shipping?

VGM is important because it helps ensure safe and smooth shipping operations. Incorrect container weight can create serious risks at ports and during sea transport.

Here’s why VGM matters:

Prevents overloading of ships.
Helps maintain vessel stability.
Reduces the risk of container collapse.
Improves safe cargo handling.
Supports proper stowage planning.

Wrong weight declarations can lead to accidents, cargo damage, and operational delays. In some cases, shipping lines may impose penalties or refuse to load the container.

Who is Responsible for VGM Submission?

The shipper named on the Bill of Lading is legally responsible for submitting accurate VGM. A CHA (Customs House Agent) or freight forwarder can submit on their behalf - but the liability stays with the shipper.

How to Calculate Verified Gross Mass?

SOLAS recognises two methods. Both are equally valid - the right choice depends on your cargo type and available equipment.

Method 1: Weigh the Packed Container

The entire packed and sealed container is weighed using certified weighbridge equipment. This is the most widely used method.

1. Pack and seal the container completely.
2. Take it to a certified weighbridge.
3. Record the gross weight reading.
4. Use this figure directly as the VGM.

Example: Packed container weighs 13,000 kg on the weighbridge → VGM = 13,000 Kg.

Method 2: Calculate by Adding All Weights

Each item inside the container is individually weighed and added to the container tare weight. The weighing must still use certified scales.

1. Weigh all cargo items individually.
2. Add packaging, wrapping, and strapping weight.
3. Add pallet or dunnage weight.
4. Add the container tare weight (printed on the container door).
5. Total = VGM.

Example: Cargo (10,000 kg) + Packaging (500 kg) + Pallets (300 kg) + Tare (2,200 kg) = VGM of 13,000 kg.

How to Submit VGM: Step-by-Step Process

After calculating the Verified Gross Mass, it must be submitted to the shipping line before the VGM cut-off time.

1. Calculate VGM using Method 1 or Method 2.

2. Log in to the shipping line's online portal.

3. Enter shipment details: container number, shipping bill number, VGM figure, calculation method, and shipper details.

4. Submit before the cut-off. Review everything, then confirm submission.

5. Download the confirmation receipt for your records.

6. Via CHA or EDI (optional): Your freight forwarder or CHA can submit through EDI on your behalf.

Intoglo helps exporters coordinate directly with shipping lines for accurate, on-time VGM submission before cut-off and provides tracking and documentation support to reduce delays or rejection risks.

What Happens if VGM is Not Submitted?

The rule is simple: No VGM, No Load. Your container will not be loaded onto the vessel. This triggers a chain of problems:

Shipment delays
Container rollover
Demurrage charges
Storage and re-handling costs

VGM Charges and Tolerance Limits

VGM is not always free. Charges may apply:

Weighbridge fees for certified weighing
Terminal handling charges for VGM processing
Correction charges if you need to update an incorrect VGM declaration

Most shipping lines allow a 2–5% variation between declared and actual weight. However, this tolerance is not universal - always check with your specific shipping line and port of loading.

Common Mistakes to Avoid in VGM

An incorrect VGM submission can lead to shipment delays, penalties, and loading issues. Here are some common mistakes exporters should avoid:

Declaring an incorrect container weight
Missing the VGM submission deadline
Using an incorrect VGM calculation method
Ignoring allowed VGM tolerance limits
Not following shipping line or country-specific VGM rules

Managing VGM compliance, shipping documentation, and cut-off timelines correctly is important in container shipping. Working with an experienced freight forwarder helps reduce documentation errors, avoid delays, and ensure smoother shipment execution.

Conclusion

VGM compliance is an essential part of international container shipping and directly impacts vessel loading and shipment timelines. For exporters, accurate weight declaration, timely submission, and the use of certified weighing methods are necessary to avoid delays, penalties, and additional shipping costs.

FAQs

Is a VGM submission mandatory for all export containers from India?

Yes, under SOLAS regulations, VGM submission is mandatory for all packed export containers worldwide, including all shipments from Indian ports. No exemptions apply based on cargo type or destination.

Can a freight forwarder submit VGM on my behalf?

Yes, your CHA or freight forwarder can submit VGM through the shipping line portal or EDI. However, the legal responsibility for the accuracy of the declared weight remains with the shipper on the Bill of Lading.

What is the allowed VGM tolerance limit?

Most carriers and ports allow a 2–5% variation between declared VGM and actual weight at the terminal. However, this tolerance differs by shipping line and country - always confirm with your carrier before submission.

What happens if I submit an incorrect VGM?

You may face correction charges, vessel loading refusal, or penalties from the shipping line. If the difference exceeds the permitted tolerance, your container could be offloaded or rolled to the next vessel.

Does the container tare weight count in VGM?

Yes, always. The tare weight of the empty container is a mandatory component of VGM under both calculation methods. It is printed on the container door panel and must be included in every VGM declaration.
