Demystifying the UIIA: The Essential Guide to Intermodal Drayage and Insurance Compliance

Hauling intermodal containers is one of the most lucrative sectors in commercial transport, but entering port facilities and rail ramps requires clearing a critical regulatory hurdle: the Uniform Intermodal Interchange Facilities Agreement (UIIA).

Navigating intermodal drayage requires specific knowledge of hold-harmless agreements, equipment interchanges, and specialized endorsements. With over 35 years of hands-on experience helping truck drivers and motor carriers secure specialized commercial auto policies, our agency has seen firsthand how a single missing endorsement can halt an owner-operator at the port gate. This comprehensive guide breaks down what the UIIA is, why it matters, the strict insurance mandates involved, and how belonging to the program helps scale your trucking business.

The UIIA is a standard industry contract administered by the Intermodal Association of North America (IANA). It governs the interchange of intermodal equipment between equipment providers (ocean shipping lines, rail ramps, and chassis pools) and motor carriers.

To learn more about the organization directly, you can visit the Official Uniform Intermodal Interchange Facilities Agreement Website.

If you plan to haul ocean containers or piggyback trailers, you must belong to the UIIA. Marine terminal operators and railroad facilities require truckers to maintain an active, fully compliant UIIA registration before granting entry to their yards. Without UIIA compliance, your trucks cannot interchange equipment or pull containers off port properties or rail ramps.

While standard Federal Motor Carrier Safety Administration (FMCSA) rules mandate $750,000 in primary auto liability for general freight, the UIIA enforces higher limits and stricter policy conditions.

To review the complete framework, check out the Official UIIA Insurance Requirements Page.

Here is a detailed breakdown of what the UIIA and its participating providers require:

• Auto Liability ($1,000,000 Combined Single Limit): Must be written as “Any Auto” or include “Scheduled & Hired Autos”. Standard “Scheduled Auto Only” policies without hired auto coverage will be rejected by the UIIA system.

• Commercial General Liability ($1,000,000 Per Occurrence / $2,000,000 Aggregate): Protects against non-driving liabilities around terminals and yards, with no self-insured retention (SIR) allowed.

• Motor Truck Cargo Insurance: Most individual Equipment Providers require $100,000 in cargo coverage to safeguard the goods inside the container.

• Trailer Interchange Insurance: Physical damage coverage protecting non-owned trailers or chassis while in your care, custody, and control. Typical limits range from $30,000 to $65,000 per unit. Standard “Non-Owned Trailer Physical Damage” is frequently rejected because it only applies when attached to your power unit, whereas Trailer Interchange applies regardless of attachment.

• Workers’ Compensation & Employer’s Liability: Mandatory depending on state laws and specific equipment provider addenda.

One of the biggest tripping points for intermodal motor carriers is policy language. A standard commercial auto policy is not sufficient on its own. The UIIA explicitly mandates that your insurer attach the CA 23-17 endorsement (also known as the UIIE-1 or TE 23-17B form) to your auto liability coverage.

Review the exact legal document via the link to the Official CA 23-17 Endorsement Form Specimen.

The CA 23-17 form is a specialized hold-harmless and indemnity endorsement designed for intermodal transport. It legally modifies your auto liability policy so that:

1. It automatically grants additional insured status to any UIIA Equipment Provider whose equipment you interchange.
2. It mandates that your insurance policy will act as primary coverage in the event of an accident or loss involving interchanged equipment.
3. It confirms that the insurer will provide 30 days’ advance notice of cancellation directly to the UIIA clearinghouse.

Without this specific endorsement generated and filed electronically into the UIIA database by your insurance company, your account will remain inactive.

If you operate on the Gulf Coast or mid-state corridors, explore options on our commercial truck insurance Tampa page to verify that your endorsements match local port demands.

Signing up for the UIIA is only step one; you must also register with individual Equipment Providers (EPs) within the UIIA portal.

An Equipment Provider is an ocean carrier (e.g., Maersk, MSC, CMA CGM), a railroad operator (e.g., CSX, Norfolk Southern, Union Pacific), or a chassis pool owner (e.g., TRAC Intermodal, DCLI) that owns or controls intermodal containers and chassis.

When you join the UIIA, you select the specific EPs you plan to haul for. Each EP maintains an “Addendum” to the standard UIIA agreement that may require specific additional insurance limits or customized cargo endorsements.

Carriers moving intermodal loads out of Georgia’s major ocean terminals can review regional requirements on our Savannah commercial truck insurance page and broader coverage details on our Georgia commercial truck insurance page.

Belonging to the UIIA transforms your motor carrier authority from a general dry-van operator into a versatile intermodal carrier.

• Streamlined Gate Access: The UIIA acts as a single centralized clearinghouse. Instead of executing dozens of individual contracts with every ocean line and railroad, one UIIA agreement gives you access to over 60 different equipment providers.

• Automated Insurance Tracking: Once your agent submits your insurance filings electronically, the UIIA automatically transmits proof of insurance (the 5C form) to all your selected EPs.

• Business Growth & High-Demand Freight: Intermodal container shipping offers steady freight volume year-round. Becoming UIIA-approved opens up high-paying drayage contracts, port pulls, rail ramps, and spot-market container moves that non-UIIA fleets cannot touch.

• Higher Broker Confidence: Freight brokers and freight forwarders value UIIA carriers because it proves high operational standards, proper insurance limits, and active legal compliance.

Getting registered with the UIIA requires having your operating credentials organized in advance. Follow these steps to apply:

1. Maintain Active FMCSA Authority: Ensure your USDOT and MC numbers are active and in good standing.
2. Obtain a SCAC Code: Before starting your UIIA application, you must possess a SCAC code.
3. Register Online with the UIIA: Visit the UIIA registration portal, enter your company details, EIN, SCAC code, and select your Equipment Providers. Pay the annual UIIA participation fee.
4. Bind Compliant Insurance: Secure your $1,000,000 auto liability, general liability, cargo, and trailer interchange policies.
5. Have Your Agent Submit Filings: Your insurance agency must electronically upload the certificate of insurance and the mandatory CA 23-17 endorsement into the UIIA system.

A Standard Carrier Alpha Code (SCAC) is a unique two-to-four-letter identification code used to identify transportation companies in computer systems and shipping documents. Issued by the National Motor Freight Traffic Association (NMFTA), a SCAC code is mandatory for intermodal tracking, customs documentation, and UIIA participation.

Carriers servicing industrial distribution corridors in the Midwest can review local insurance resources on our Cleveland commercial truck insurance page and our Ohio commercial truck insurance page.

Not all insurance companies write intermodal drayage policies, and many standard markets refuse to offer the mandatory CA 23-17 endorsement. Furthermore, captive insurance agents who work for a single insurance brand often lack access to carriers that accept UIIA filings.

The best way to secure UIIA-compliant coverage is by partnering with an independent insurance agent.

An experienced independent agent:

• Accesses multiple specialty trucking insurers who actively issue CA 23-17 endorsements.

• Understands how to structure “Scheduled and Hired Auto” clauses correctly to prevent registration rejections.

• Matches Trailer Interchange limits to the exact requirements of your chosen Equipment Providers so you don’t overpay for unneeded limits or get turned away for insufficient ones.

• Handles direct electronic filings with the UIIA clearinghouse to eliminate gate delays.

If your routes extend into major Gulf Coast freight corridors, discover options on our Houston commercial truck insurance page, our Brownsville commercial truck insurance page, or our comprehensive Texas commercial truck insurance page.

Entering the intermodal container sector can transform your trucking business, but success depends on having the right filings and insurance endorsements in place from day one. Don’t let policy misconfigurations or missing endorsements keep your trucks parked outside the port gates.
