Drayage is the retrieval of shipping containers from ports and hauling them to inland locations such as rail heads, distribution centers, or stores. Ports in the US struggle to position chassis efficiently, and chassis shortages are a key contributor to port congestion. The issue of chassis maintenance and repair is also a sticking point in employer negotiations with longshore labor unions.
US importers shipping through various ports are often concerned about such challenges as congested marine terminals, lengthy truck turn times, equipment shortages, and distribution warehouses stuffed beyond capacity for weeks or longer. Major gateways also experience various degrees of equipment shortages, and delays in the return of empty containers. Some ports in Asia could also risk experiencing a shortage of empty containers.
