A bill of lading is a very important document used in the transport of freight. After all, very relevant information about your shipment. Firstly, is the obvious section for the shipper and consignee. However, an often misunderstood section is contained within the body of the bill of lading. The section for the required freight class and NMFC is arguably the most important part. If this section is not filed out correctly it can lead to very unpleasant surprises.
