Intermodal carriers operate at the intersection of rail, ocean, and highway networks. The Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) governs the majority of equipment transactions between motor carriers, railroads, and ocean carriers. When combined with the Surface Transportation Board’s EP-743 ruling on demurrage and detention, these frameworks create both compliance obligations and opportunities for operational automation.
UIIA Insurance Certificate Automation
Most UIIA participants require current certificates of insurance on file before equipment can be interchanged. Manual certificate uploads lead to delays and rejected transactions. Modern TMS platforms (Truckmate, McLeod, TMW) can be configured to monitor expiration dates and automatically transmit updated ACORD 25 certificates via the UIIA API. SQL-based monitoring queries that join the carrier’s insurance table with the UIIA equipment log table can trigger renewal workflows 45 days before expiration, eliminating last-minute rejections at terminal gates.
Electronic Interchange Receipt (EIR) Validation
Accurate capture of equipment condition at interchange is critical for dispute defense. EDI 214 status messages and API callbacks from rail and ocean carriers can be parsed in real time. A well-designed integration layer validates the returned EIR against the driver’s ELD GPS timestamp and the load’s EDI 204 pickup window. Discrepancies are flagged before the driver leaves the terminal, protecting the carrier from unwarranted per-diem or demurrage charges.
| Data Element | Source | Typical Latency | Dispute Value |
|---|---|---|---|
| Gate In / Gate Out Timestamp | Rail / Ocean API | 2-8 minutes | Primary evidence for free-time calculation |
| Equipment Condition at Interchange | EIR via UIIA API | Real-time | Prevents false damage claims |
| Insurance Certificate Status | Internal SQL + UIIA | Instant | Avoids equipment hold fees |
| Driver ELD GPS Snapshot | Telematics feed | < 60 seconds | Corroborates arrival time for EP-743 defense |
EP-743 Demurrage Dispute Automation
The STB’s EP-743 ruling requires railroads and ocean carriers to provide reasonable free time and clear notice of charges. Carriers that compile structured evidence packages (timestamped EIRs, GPS records, EDI 214 sequences, and insurance status) can submit disputes through each carrier’s API portal with minimal manual effort. SQL views that aggregate these records into a single dispute packet have been shown to reduce average resolution time from 28 days to under 7 days.
Independent by design
Strong Tower Consulting, LLC and Exspeedite LLC are separately organized sister companies under common ownership (separate EINs; liability firewall). We provide process and integration guidance only. Carriers retain full control of their chosen TMS (Truckmate, McLeod, TMW) and never have to buy our software.
Implementation Roadmap
A typical engagement begins with a review of the carrier’s current SQL schema for insurance, equipment, and settlement tables. From there we map required EDI 204/214/210 transaction fields to UIIA and ocean carrier API endpoints. The resulting architecture supports automated certificate filing, real-time EIR validation, and one-click EP-743 dispute packages while preserving the carrier’s existing driver settlement and fuel surcharge processes.

Frequently Asked Questions
What is the most common reason for UIIA equipment hold?
An expired or missing certificate of insurance on file with the UIIA repository. Automated daily SQL queries that compare internal insurance records against the UIIA response can prevent 90 percent of these holds.
How does EP-743 change demurrage dispute strategy?
The ruling requires carriers to receive clear notice and reasonable free time. Structured evidence packages that combine GPS, EIR, and EDI timestamps satisfy the “reasonable effort” standard and dramatically improve dispute success rates.
Can existing TMS platforms support UIIA API automation?
Yes. Truckmate, McLeod, and TMW all support custom scripting or API extensions. The key is mapping the correct SQL tables (insurance, equipment status, driver settlement) to the UIIA and ocean carrier endpoints.
Do I need to replace my current TMS to implement these automations?
No. Our approach focuses on integration and process optimization around your existing system. Strong Tower Consulting never requires you to purchase additional software.
