UIIA
Certification
& Registration
The UIIA (Uniform Intermodal Interchange and Facilities Access Agreement) is an industry-standard agreement that governs the relationship between trucking companies, equipment providers, and intermodal facilities. It ensures that everyone involved in moving intermodal freight follows clear, consistent rules for equipment use and liability.
The standard for intermodal access
In simpler terms, the UIIA is the agreement that connects trucking companies with the equipment and facilities they need to move intermodal freight:
Trucking companies sign the UIIA to use containers, chassis, and other equipment
It defines who is responsible for repairs, insurance, and safety
It streamlines the process and reduces disputes between parties
Managed by IANA and widely used across the freight transportation industry
Why get UIIA certified?
Access intermodal equipment — containers, chassis at ports and rail yards
Clear liability rules — know who is responsible for repairs and insurance
Industry standard — recognized by steamship lines, railroads, and terminal operators
Streamlined operations — fewer disputes, faster processing at intermodal facilities
Any carrier accessing intermodal freight needs certification
In short, any trucking company or motor carrier that wants to haul intermodal freight or access ports, rail yards, or equipment needs to be UIIA-certified. This certification ensures they have the proper insurance and follow the rules set by equipment providers and facilities.
Trucking Companies (Motor Carriers)
To pick up and transport intermodal equipment such as containers and chassis from rail yards, ports, and intermodal facilities. Without a UIIA agreement, trucking companies cannot legally access or use this equipment.
Examples: Independent owner-operators, small trucking businesses, or larger fleets involved in intermodal transport.
Equipment Providers
To set the rules for how their equipment (containers, chassis) is used, returned, maintained, and insured by trucking companies.
Examples: Steamship lines, railroads, and leasing companies.
Facility Operators
To ensure that all parties using their facilities follow consistent safety, liability, and equipment handling rules.
Examples: Terminal operators and intermodal facility managers.
Freight Brokers & Logistics Providers
While they don't sign the UIIA themselves, brokers often work with trucking companies that must be UIIA-compliant to handle intermodal freight.
Brokers and logistics providers depend on UIIA-certified carriers to move intermodal loads.
