All About Tonnage

On November 19th, 2019, IRPT hosted a webinar titled "All about Tonnage", presented by Inland Rivers, Ports & Terminals, Inc. and the Institute of Water Resources and Waterborne Commerce Statistics Center.

Over the past year since the signing of our Memorandum of Common Purpose, IRPT, IWR and WCSC has been working together to ensure all ports within the United States are recognized and their tonnage is properly assigned to each statistical boundary.

To check if your port's boundary is identified correctly by WCSC, please view the map here:

On the webinar, we covered how we have accomplished this, what is still to be done and our next steps: Properly recognizing and updating operating docks within port boundaries. To learn more about tonnage, please visit:
