The National Motor Freight Classification (NMFC)® |
The NMFC Data update lifecycle occurs two times a year, beginning with a Proposal and culminating in the publication of a Supplement. The NMFC Book is then updated and republished every January to show the full updates from the previous years' Supplements. You can use the flowchart and table of definitions below to understand the timeline of how these data updates are created and adopted.
