How do I measure my verified gross mass container weight?

The Verified Gross Mass (VGM) is the weight of the cargo including dunnage and bracing plus the tare weight of the container carrying this cargo. SOLAS requires the shipper to provide VGM in a “shipping document,” either as part of the shipping instruction or in a separate communication, before vessel loading.

The shipper is obliged to verify the gross mass of the containers carrying their cargo by either of two permissible weighing methods before these containers can be loaded on a vessel.

Method 1  Requires weighing the container after it has been packed.

Method 2  Requires weighing all the cargo and contents of the container and adding those weights to the container’s tare weight as indicated on the door end of the container.

This method will not be practical for shippers of bulk commodities like scrap, grain, etc., and it will be up to local authorities to grant permission to use this method.

To find the Tare weight of your container, please visit Maersk.com/tare.
