Title 49 › Subtitle SUBTITLE III— - GENERAL AND INTERMODAL PROGRAMS › Chapter CHAPTER 59— - INTERMODAL SAFE CONTAINER TRANSPORTATION › § 5902
If the first carrier a loaded container or trailer is given to is a motor carrier and the projected cargo weight is more than 29,000 pounds, the person handing it over must tell that motor carrier the gross cargo weight and a short description of what is inside before giving the container or trailer. If the actual weight is more than 29,000 pounds, the person giving the container or trailer must also provide a written or electronic certification before or when they hand it over. That certification must include the actual gross cargo weight, a reasonable description of the contents, who certified it, the container or trailer number, and the date of certification (or the date the data was moved to another document). A carrier may copy that info onto another document or into electronic form, but must note the date and who made the transfer. A shipping document with the required information counts as the certification. The term “Freight All Kinds” (FAK) cannot be used as the commodity description after December 31, 2000, if any single commodity makes up 20 percent or more of the total weight. If a separate paper is used, it must be clearly marked “INTERMODAL CERTIFICATION.” These rules apply to anyone who first gives a container or trailer for intermodal transport in the United States. Carriers, agents, brokers, customs brokers, freight forwarders, warehousers, and terminal operators must pass the certification to the next carrier before or when the container or trailer is handed to that next carrier. If no certification is received, the next carrier may assume none was required. Passing the paper does not mean the sender checked it for accuracy. If someone forwards wrong information or fails to forward the certification and another carrier pays a bond, fine, penalty, cost (including storage), or interest because of that mistake, the person who made the mistake must pay those amounts. The carrier that pays can place a lien on the container’s contents for those amounts plus court costs and legal fees. The notification and certification rules do not apply to consolidated shipments loaded by a motor carrier if that motor carrier does the highway part or agrees to take responsibility for any weight fines. They also do not apply when a carrier is merely passing a loaded container or trailer to another carrier unless that carrier was the one who first gave it to a carrier. A carrier or agent is not treated as the person who gave the container unless they legally took responsibility for loading it.
