NEW WEIGHT REGS FOR OCEAN SHIPMENTS
Effective July 1, a new international law passed by the International Maritime Organization will go into effect, as the SOLAS (Safety of Life at Sea) Act will require that shippers provide a verified gross weight for all containers in international trade.
Containers without this certified weight will not be accepted for ocean transport. The containers will then have to be weighed at the port and a charge for this may be passed on to the shipper. Fines for non-compliance will vary from country to country and could range from fines to imprisonment.
Most countries seem to be adopting a tolerance level of 5% allowance in the reported weight. The two commonly accepted methods to achieve the VGM (verified gross mass) are detailed on the attached link.
