An equipment interchange receipt, or EIR, is the document signed at a terminal gate that records a shipping container’s condition and the exact time custody passes between the terminal and the trucker. It exists to answer one question after the fact: who had the box, and what shape was it in, when liability moved? The Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) defines it as “a document confirming the interchange of Equipment between Parties to this Agreement, or their agents,” with condition described either in writing on the receipt or through “Recorded Images taken at the time of Interchange.”1Intermodal Association of North America. Uniform Intermodal Interchange and Facilities Access Agreement Everything else about the receipt flows from that single evidentiary job.
What the Receipt Records
Four pieces of information do the real work.
The container identification number comes first, formatted under the ISO 6346 standard: four letters followed by seven digits, with a check digit at the end used to verify transmission accuracy.2ISO (International Organization for Standardization). ISO 6346:2022 – Freight Containers – Coding, Identification and Marking Before accepting the unit, the driver should confirm the number painted on the container matches the booking or release documents.
The high-security seal number is next. Seals must meet ISO 17712 standards, and any mismatch between the number stamped on the seal and the number on the shipping documents should be flagged on the spot, because it can signal tampering, theft, or a loading error.3U.S. Customs and Border Protection. C-TPAT Bulletin – Compliance With ISOs 17712 Standards for High Security Seals
The condition section captures every visible defect through standardized damage codes on a diagram of the container’s front, back, sides, roof, and undercarriage. The clerk notes dents, holes, structural warps, gasket damage, and problems with corner castings, locking bars, or the floor. Anything not recorded before the driver signs becomes, for practical purposes, invisible in later disputes.
Finally, the EIR carries the exact date and time of interchange. That timestamp fixes when custody shifted and starts the clock on demurrage, detention, and chassis per diem charges.
What Happens at the Gate
At most modern terminals, a truck pulls into a dedicated lane where optical character recognition cameras scan the container number and tractor plates and photograph each side of the box for damage. If the system flags something, the vehicle is diverted to a manual inspection station where a gate clerk performs a walk-around.
The driver has their own federal inspection obligations before leaving the facility. Under 49 CFR 392.7, a driver accepting intermodal equipment must confirm that specific components are in working order:4eCFR. 49 CFR 392.7 – Equipment, Inspection and Use
- Service brake components visible without going under the vehicle, plus trailer brake connections
- All lamps, markers, and conspicuity marking material
- Rims, lugs, and tire condition
- Air line connections, hoses, and couplers
- King pin and upper coupling device
- Chassis rails, support frames, tie-down bolsters, and sliding frame locks
- Locking pins, clevises, clamps, and hooks
Intermodal equipment providers have matching duties. They must maintain space at their facilities for drivers to perform this pre-trip inspection, so a terminal cannot rush a driver through the gate without room to look the equipment over. If the driver or clerk finds a defect that could affect safety, the provider must repair or replace the equipment before departure, and the provider must certify on the driver’s report that repairs were completed before the unit returns to service.5GovInfo. 49 CFR 390.40T – Intermodal Equipment Provider Responsibilities6eCFR. 49 CFR 396.12 – Procedures for Intermodal Equipment Providers
Then the system prints or transmits the receipt. The driver reviews the listed defects, confirms they match what they see on the ground, and signs. That signature is the moment liability shifts. If the driver spots damage not on the receipt, the time to say so is before signing, not after the gate arm lifts.
How a Signed Receipt Shifts Liability
The UIIA is the standard contract between trucking companies and equipment providers (ocean carriers, railroads, and leasing companies), and it treats the EIR as the defining record of liability transfer.7Intermodal Association of North America. UIIA FAQ Both parties must execute an EIR at the time of interchange describing the equipment and any observable damage, excluding reasonable wear and tear.1Intermodal Association of North America. Uniform Intermodal Interchange and Facilities Access Agreement
A clean EIR, one with no damage noted, puts a heavy burden on the trucking company if the equipment comes back damaged. The last party to sign a clean receipt is typically held financially responsible for repairs, which can run from a couple hundred dollars for a patch to several thousand for structural work. Courts and arbitrators treat the EIR as the definitive evidence of condition at handoff, so without a noted exception, the trucker’s company usually loses the right to contest repair invoices from the container line.
When a Clean Receipt Doesn’t End the Argument
The clean-receipt presumption has limits. Some damage is simply not visible during a gate inspection. A floor can be structurally compromised while looking fine from underneath, and internal corrosion can weaken a panel in a way no walk-around catches. Under the Carriage of Goods by Sea Act, which governs the ocean leg, carriers are not liable for “latent defects not discoverable by due diligence,” along with acts of God, perils of the sea, and a list of other enumerated exceptions.8Office of the Law Revision Counsel. 46 USC 30701 – Definition The burden of proving an exception falls on whoever claims it.
COGSA’s “apparent good order and condition” standard technically applies to bills of lading between ocean carrier and shipper, not directly to the EIR between a terminal and a trucker. In practice, though, the EIR feeds into COGSA disputes as evidence. If an outbound receipt at the port showed no damage and the inbound receipt at the destination warehouse shows a hole, that paper trail helps establish when and where the damage occurred.
Split Container and Chassis Providers
Liability gets messier when the container and the chassis under it come from different providers. A trucking company might pick up a container owned by an ocean carrier riding on a chassis leased from a separate pool operator, and the driver may be signing two overlapping sets of terms at once. When chassis are leased to the terminal by a third-party provider that participates in the UIIA, the motor carrier must be a UIIA signatory in good standing to use them. A driver who documents container defects but not chassis defects can end up liable for damage to equipment they did not realize fell under a different agreement.
What the Timestamp Costs You
The receipt’s time field controls three different equipment charges that are easy to confuse. Demurrage accrues while a loaded container sits inside the terminal after the carrier’s free time expires. Detention starts once the container leaves the terminal and runs until it is returned empty. Per diem applies to chassis usage and runs on its own clock. All three reference the dates and times on the EIR.9Seaboard Marine. Demurrage and Detention
The Federal Maritime Commission has tightened the rules around how these charges can be billed. Under 46 CFR Part 541, a billing party must issue a demurrage or detention invoice within 30 calendar days of the date the charge was last incurred, or the billed party has no obligation to pay.10Federal Register. Demurrage and Detention Billing Requirements The invoice must also go to the correct party, either the person who contracted for the ocean transportation or the consignee, and an invoice missing required information eliminates the obligation to pay. This gives the EIR timestamp real teeth: if the billing party’s invoice does not line up with the interchange times on the receipt, that is grounds to challenge the charges.
Reefers and Hazmat
When the container is refrigerated, the EIR needs more than a damage sketch. The driver and clerk should confirm that the temperature setpoint matches the transport instructions, and ventilation, humidity, and controlled atmosphere settings should be recorded when they apply. A reefer taken out with the wrong setpoint can destroy a load of produce or pharmaceuticals in hours, and without those values on the receipt, the trucker’s company has no defense when the cargo claim arrives.
Hazmat moves add a placard check. Federal regulations require freight containers holding hazardous material to display the correct placards on each side and each end, and for the most dangerous categories (explosives, poison gas, radioactive) placarding is mandatory regardless of quantity. Less dangerous categories allow an exemption when the total weight falls below 454 kilograms, about 1,001 pounds.11eCFR. 49 CFR 172.504 – General Placarding Requirements The EIR should reflect that placards are in place and match the shipping documents, because a trucker who drives off with missing or incorrect placards is violating federal hazmat law from the moment the gate opens.
Disputing a Repair Invoice
Damage claims are where EIR accuracy either saves or costs the trucking company real money. Under the UIIA’s default dispute process, a motor carrier has 30 calendar days from receipt of a repair invoice to dispute it in writing. Miss that deadline and the carrier loses the right to dispute the invoice, pursue binding arbitration, or raise any other defense. Individual providers may set different timelines in their UIIA addenda, so the specific provider’s terms are worth checking before assuming 30 days.1Intermodal Association of North America. Uniform Intermodal Interchange and Facilities Access Agreement
The UIIA also caps how long a provider can wait to send a repair invoice at all. For standard manned-gate interchange, the provider must issue the invoice within 165 calendar days of the interchange date. When the gate uses recorded images instead of a manual inspection, that window drops to 120 days. If the equipment was repaired during the interchange period while the trucker still had it, the deadline is 90 days. Invoices arriving after those windows are worth challenging immediately.
A strong dispute almost always starts with the EIR itself. If the damage the provider is billing for was already noted on the outbound receipt, the trucker has clear grounds for rejection. Timestamped and geotagged photos taken at the gate serve as powerful supporting evidence, which is why experienced drivers photograph existing scratches and dents before signing even when the clerk has already coded them on the receipt.
Electronic Receipts and How Long to Keep Them
Most high-volume terminals now generate EIRs electronically rather than on carbon paper. The federal E-SIGN Act gives these digital records the same legal weight as paper ones: under 15 U.S.C. ยง 7001, a signature or record “may not be denied legal effect, validity, or enforceability solely because it is in electronic form.”12Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity For an electronic EIR to hold up, it has to accurately reflect the underlying transaction, remain accessible to everyone legally entitled to see it for the required retention period, and be reproducible later.
The UIIA also expressly allows recorded images taken at interchange to substitute for a written damage description. Terminals using automated gate imaging can generate an EIR entirely from camera footage, with damage visible in the photos replacing handwritten codes. One trade-off of the faster image-based process is the tighter invoicing window noted above: 120 days instead of 165.
Retention requirements depend on what moved. For hazardous waste shipments, shipping papers must be kept for three years from the date the initial carrier accepted the material; all other hazardous materials require two years.13eCFR. 49 CFR 172.201 – Preparation and Retention of Shipping Papers Intermodal equipment providers must keep driver defect reports and repair certifications for at least three months.6eCFR. 49 CFR 396.12 – Procedures for Intermodal Equipment Providers For non-hazmat interchange, the UIIA invoicing and dispute timelines effectively set a practical floor: since providers can invoice up to 165 days after interchange and motor carriers then have 30 days to dispute, keeping EIRs for at least seven months covers the full exposure window. Many carriers retain them for two to three years as internal policy, which is the safer approach given that contract claims can surface well after the UIIA deadlines pass.
