What is VGM?

SOLAS Verified Gross Mass

Since July 2016, the International Maritime Organization (IMO) requires that every packed container must have its verified gross mass (VGM) declared before loading onto a vessel. This is mandated under the SOLAS Convention (Safety of Life at Sea) to prevent overweight containers from causing vessel instability and port accidents.

Two Approved Weighing Methods

Method 1
Weigh the packed, sealed container using calibrated equipment (weighbridge, crane scale, or other certified device).
Method 2
Weigh all packages and cargo items separately, add the tare weight of the container, and sum up to get the total gross mass.

Penalties for Non-Compliance

Containers without a valid VGM will not be loaded onto a vessel. This means your cargo gets rolled to the next available sailing, potentially adding 1-2 weeks to transit time. Additionally, most terminals charge a $100+ per container penalty for late VGM submissions, and re-booking fees can apply.

Cutoff Times Vary by Port

While the general rule is to submit VGM 24 hours before vessel ETD, some ports and terminals have stricter rules. Chinese ports typically require 48 hours, and specific terminal operators may have their own cutoff schedules. Always check with your local terminal for the exact cutoff.
