Starting July 5, 2021, FedEx Freight will assess a $30.00 per shipment peak surcharge on shipments governed by the FedEx Freight 100 Series Rules Tariff and destined to a limited list of ZIP codes in areas with the greatest capacity constraints in the FedEx Freight network.
A ZIP Code list will be available for customers on the updated fedex.com pages, I have also attached the list for you to review.
