We've curated a list of standard heavy equipment shipped and have made blank bill of lading template downloads available. This draft standard for trial use contains the format and establishes the data contents of the motor carrier bill of lading transaction set (211) for use within the context of an electronic data interchange (edi) environment. Simply find the equipment you're transporting and download the right bol to fill out. Pro numbers are 9 or 10 (with a check digit) numbers. The surrender of the original straight bill of lading, properly endorsed, is required by transportation lines upon delivery of the freight, in accordance with the terms of the bill of lading.
