After attending several meetings with industry professionals discussing the new container weight requirement I found the challenge will be for the shipper, who will be responsible for getting that weight. Each terminal and carrier are allowed to choose how they will handle this new requirement. Some will turn containers away and some will not, but terminals who do not turn away containers will roll them over to the next vessel and charge fees in accordance with this service. Weighing services, for a fee, may also be available at some terminals but the trick is to know how each terminal operates and to find out in advance.
