On July 1, 2016, a new Safety of Life at Sea (SOLAS) convention of the International Maritime Organization (IMO) took effect, requiring shippers to verify the gross mass of a container carrying cargo.

To the side you may find a helpful infographic from the Journal of Commerce explaining how the expanded SOLAS requirements work, as well as an in-depth pdf guide (downloadable).
