The new container weight rules, which are nicknamed within the industry as VGM (Verified Gross Mass) but technically known as SOLAS (Safety of Lie at Sea) amendments, are set to start July 1, 2016. The VGM/SOLAS rules are mandatory for all packed containers received for transport (gate-in or off-rail) and state that the Shipper is responsible for providing the VGM to the carrier. The VGM must be received by the carrier before the container can be lifted onto a vessel at the port of loading. Failure to provide VGM will mean the ship’s master is required, by law, to refuse the container for carriage. Verified Gross Mass is calculated by adding the tare weight of the container and weight of cargo.
