The intermodal drayage industry continues to face systemic equipment mismatches that generate millions in unbilled driver dwell time, excess fuel consumption, and unrecoverable chassis per diem charges. When an ocean carrier directs a motor carrier to retrieve a bare chassis from an off-dock depot located several miles from the marine terminal, the resulting split mission creates significant operational friction that most TMS platforms fail to capture automatically.
Strong Tower Consulting has developed proven dispute defense architectures that allow intermodal carriers running Truckmate, McLeod, TMW, or Profit Tools to both recover legitimate chassis split accessorials and systematically defeat unlawful per diem and demurrage invoices issued by ocean carriers and marine terminal operators.
The Intermodal Equipment Mismatch Nightmare
Ocean carriers and terminal operators routinely require drayage drivers to perform separate pickups for containers and chassis. A driver may be dispatched to a terminal for a loaded container only to discover the assigned chassis is located at a distant bare-chassis depot. The resulting deadhead miles, additional gate transactions, and extended driver hours are rarely captured in standard EDI 214 status messages or driver settlement routines.
This pattern repeats daily at major port complexes. The financial impact compounds when ocean carriers then issue per diem invoices for chassis that were unavailable for dual missions or when terminals were closed or congested. Federal Maritime Commission interpretive rules under the Ocean Shipping Reform Act (OSRA) provide powerful leverage to challenge these charges when supported by immutable evidence.
Chassis Split & Per Diem Accounting Matrix
The following operational matrix summarizes the five most common dispute scenarios, the governing UIIA provisions, typical carrier tariff recovery amounts, ocean carrier rejection probability, and required evidentiary package components.
| Dispute Scenario | UIIA Provision | Typical Split Fee | Rejection Probability | Key Evidence Required |
|---|---|---|---|---|
| Terminal Dual Mission Failure | Section 6 - Equipment Availability | $225 | Low (18%) | TIR, GPS geofence, terminal refusal log |
| Bare Chassis Depot Repositioning | Section 7 - Chassis Split | $275-$350 | Medium (34%) | Depot & terminal GPS breadcrumbs, dispatch record |
| Bad Order Container Chassis Re-Mount | Section 9 - Equipment Condition | $195 | Very Low (9%) | Bad order tag photo, inspection report, second TIR |
| Ocean Carrier Free Time Clock Dispute | Section 4 - Free Time | Full per diem reversal | Medium-High (47%) | Appointment confirmation, gate log, OSRA citation |
| Marine Terminal Congestion Lockout | FMC Interpretive Rule | Full demurrage reversal | Low (22%) | Terminal congestion notice, GPS dwell report, 214 EDI |
Defeating Unlawful Ocean Carrier Per Diem Invoices
The Ocean Shipping Reform Act of 2022 and subsequent FMC interpretive rules on demurrage and detention provide clear standards for reasonableness. Charges assessed when a marine terminal is closed, refuses dual transactions, or experiences documented congestion are frequently deemed unreasonable.
Successful defense requires systematic capture of gate timestamps, GPS breadcrumb trails, terminal appointment confirmations, and EDI 214 status updates. When these records are assembled into standardized dispute packets and submitted through the UIIA portal, recovery rates routinely exceed 70% for well-documented claims.
Automating Chassis Split Invoicing in TMS Dispatch
Modern drayage operations running McLeod, Truckmate, or TMW can implement workflow rules that automatically detect split dispatch legs. By comparing GPS geofence events at container terminals versus chassis depots, the system can generate corresponding accessorial billing line items on the EDI 210 invoice to the ocean carrier or shipper.
These rules typically reference SQL views that join dispatch, move, and equipment tables. When a move sequence contains both a bare-chassis pickup and a separate container retrieval within a defined radius and time window, the TMS automatically adds the tariff-based split fee to the freight bill. This automation eliminates reliance on manual driver notes or post-trip settlements.
Managing UIIA Dispute Submissions
Winning formal UIIA arbitrations requires immutable evidentiary packets. The most effective packages contain:
- In-gate and out-gate interchange receipts (TIR)
- GPS breadcrumb reports with precise latitude/longitude and timestamps
- Terminal gate appointment screenshots and confirmation numbers
- Bad-order equipment inspection photographs and reports
- Internal TMS dispatch records showing planned versus actual sequence
- EDI 214 status messages with exception codes

Frequently Asked Questions
What is a chassis split in intermodal container drayage?
A chassis split occurs when an ocean carrier requires a drayage trucker to pick up or terminate a bare chassis at an off-dock equipment yard miles away from the container marine terminal, adding uncompensated driving time, chassis repositioning, and gate dwell.
How much can motor carriers legally charge for a chassis split accessorial?
Carriers typically bill between $150 and $350 per occurrence under their filed accessorial rules tariff, depending on distance between the terminal and off-dock chassis depot, plus hourly driver detention if terminal wait exceeds contractual free time.
How does the Ocean Shipping Reform Act of 2022 protect carriers against unlawful per diem?
OSRA 2022 prohibits ocean carriers from assessing demurrage and detention charges when equipment cannot be returned due to marine terminal closures, appointment unavailability, or terminal refusal of dual transactions, making such per diem invoices illegal.
What evidentiary records are required to win formal UIIA per diem disputes?
Carriers must present an immutable dispute packet: in-gate interchange receipts (TIR), date/time-stamped GPS breadcrumb logs confirming terminal arrival, appointment cancellation or refusal screenshots, and internal TMS dispatch records.
