Request the weight of an export container (SOLAS method I)

VGM: Method 1


Since July 1st 2016, every packed container to be loaded on board of a SOLAS ship needs to have its Verified Gross Mass determined. Determining the weight can be done through Method 1 (weighing the packed container using calibrated and certified weighing equipment) or through Method 2 (calculation: container tare weight + weight of the goods; which requires a special permission).

The shipper provides this information to the shipping agent, who passes it on to the carrier (who needs to balance the vessel), and to the terminal (who is not allowed to load the container without the information). Several other parties could also benefit from having the weight in their digital files, e.g. CMR documents.


By using our VGM - Method 1 API, the last known verified weight and additional measurement information for these export containers can now be accessed through a central datasource. This reduces the need for companies to share this data through the traditional means of communication (phone, email, pdf). The live version of the API allows you to look up the "Method 1" VGM of a container from the moment it is available.
