Freight broker C.H. Robinson said it would begin levying drayage surcharges in September due to worsening congestion at U.S. ports.

"As you are aware, the past year has brought about unprecedented challenges for the transportation industry. Recently, it has reached a breaking point," a Thursday client advisory read." As a result, international drayage carriers servicing several ports/ramps through the U.S. have implemented congestion/peak season surcharges."

C.H. Robinson (NASDAQ:CHRW) said the surcharges will carry through the end of the year "at which time we will reevaluate."

The service advisory pointed to increased import volumes and a lack of labor and equipment as some of the reasons for elevated dwell times and congestion.

"What the industry hoped would be a short-term challenge is now forecasted to last well into Quarter 1 2022," the notice continued. "Due to this situation that is beyond our control, this fee will apply on door moves to/from the terminals."

The company will also be implementing an origin congestion surcharge for Shenzhen, China, which will begin on Sept. 6. A "significant increase" in operational costs at the port in recent weeks was the explanation given.
