Haulier is a term used to describe a company, individual or vehicle that specializes in transporting goods and materials. Hauliers often work together with shippers and carriers to provide efficient, cost-effective transport for their clients. Transporting goods by truck can be a difficult, time-consuming and expensive process, which is why hauling companies are in high demand.

Hauliers are often involved in the supply chain, helping to move goods from the producer to the consumer. They may also work with container terminals, railroads and other carriers to ensure that the goods get to their destination as quickly and cost-effectively as possible.
