The document summarizes new regulations from the International Maritime Organization (IMO) requiring shippers to provide the verified gross mass (VGM) of cargo containers before loading onto vessels. Beginning July 1, 2016, shippers must provide the VGM to ocean carriers and terminal operators, and containers without a VGM cannot be loaded onto ships. Shippers may use two methods to determine VGM and are responsible for any costs incurred if the VGM is not provided in time. Procedures for providing and submitting the VGM will vary by country.
