The container and chassis markets are separate and interdependent.
- Container market. Controlled by shipping lines and container leasing companies, which generally involves the movement of containers over long distances and across international boundaries.
- Chassis market. Controlled by Intermodal Equipment Providers (IEP), shipping lines, and motor carriers, which involves regional and local movement of containers by trucks. Chassis can also be used for terminal operations such as moving containers from loading areas to the yard and for yard storage.
