Did you know that U.S. Domestic Carriers offer a standard limit of liability on a per pound or per package basis for your shipment? GSM INTERNATIONAL has your peace of mid as our top priority. Shippers have the option to purchase Additional Cargo Liability that raises the limit of liability in the unlikely event of a lost or damaged shipment so that you receive full coverage. Our Additional Cargo Liability is based on an incremental rate per the dollar value that you request.
