Just wanted to share something that happened to me.
I recently had a lithium battery that was being shipping back via FedEx Freight.
The NMFC number that was on Kia’s bill of lading was 60680-S1
When I tried to enter that number into FedEx’s program, it would not take it. It kept saying it was improperly formatted.
Safety Regulation Strategies, Inc helped me out. By calling FedEx they got the correct NMFC number. Turns out KIA’s number was either incorrect, or not properly formatted.
