The South Carolina Ports Authority has filed a rule in our Marine Terminal Operating Schedule (Port Tariff) outlining the process for adherence to SOLAS / VGM regulations at the Port of Charleston. They feel this is a reasonable and efficient solution that will provide clarity for exporters on this long-standing concern. Summary: All export containers will be weighed on calibrated and certified truck scales on arrival at the Port of Charleston. The gross weight of the cargo and container will be provided to the respective ocean carrier as the VGM via EDI 322 message and will be made available to the stevedores stowing cargo in the port on a real time basis so that ships can be efficiently and safely stowed. No further written or electronic authorization is required of the shipper.
