Exporting a used vehicle from the US runs on two clocks
One is the title going to Customs and Border Protection. The other is the export filing reaching the carrier before the ship loads. Miss either and the unit rolls off the booking, not onto the vessel.
The two deadlines, and what each one is for
The first clock is the vehicle itself. Under 19 CFR 192.2, a used self-propelled vehicle leaving the United States by vessel has to be presented to CBP, together with its documentation, at least 72 hours before export. Where a US jurisdiction issued a Certificate of Title or a Salvage Title that is still in force, that documentation means the original title or a certified copy, plus two complete copies of it.
The second clock is the paperwork. Under 15 CFR 30.4, for vessel cargo the Electronic Export Information is filed and the filing citation given to the exporting carrier 24 hours before the cargo is loaded at the US port of lading. The Internal Transaction Number is what AES returns to confirm the filing was accepted.
They are separate obligations with separate clocks, and the one that catches people is the first. A booking can be perfectly filed and still sit on the quay because a title is in an envelope on somebody's desk. That is why the title belongs on the shipment record from the quotation onward, rather than in a folder somebody has to go and find.
Where each step sits in the shipment
The VIN arrives, and the vehicle describes itself
Vehicle attributes resolve from the VIN rather than being retyped, so make, model, dimensions, weight and the customs line come from the number itself. The same attributes decide how the unit is rated and how it is stowed.
The title is captured on the record, not in a folder
Title number and issuing state sit on the quotation and carry through to the booking, and they are searchable. A used vehicle without them is visible as a problem while there is still time to chase it, rather than 72 hours before a sailing.
The declaration will not validate without it
The AES filing carries a used-vehicle block. Where the serial type is a VIN, the filing requires the title number and the issuing state before it validates. The rule is enforced by the system rather than remembered by a person.
The ITN comes back to the unit
AES returns the Internal Transaction Number against the booking and against the individual unit. On a consignment carrying fifteen cars, that means fifteen answers rather than one, which matters when only fourteen of them cleared.
The carrier gets the citation before loading
The filing citation goes to the exporting carrier ahead of the 24-hour deadline, from the same shipment record that produced the booking, so the number the carrier receives is the number on file.
What tends to go wrong, and where it is caught
The missing title
The most common reason a used unit does not sail. It is not a filing failure, it is a documents failure, and it happens weeks earlier than anyone notices. Holding the title number and issuing state on the record from the quotation makes the gap visible while it is still cheap.
The retyped VIN
A VIN transcribed by hand into a customs form is a VIN that can be wrong on a document Customs will read. Attributes that resolve from the number itself remove the transcription step rather than double-checking it.
The consignment that half-cleared
One booking, fifteen cars, and three of them held. If the ITN attaches to the shipment rather than the unit, nobody can say which three without opening a spreadsheet. Per-unit filing records answer it directly.
The salvage unit
A salvage title still in force carries the same documentary obligation as a clean one. Treating salvage as an exception handled off-system is how a unit ends up at the port without its paperwork.
About this page
Sources and scope: The deadlines described here come from 19 CFR 192.2 (presentation of a used self-propelled vehicle and its documentation to CBP for export by vessel) and 15 CFR 30.4 (EEI filing deadlines, vessel cargo), checked on 29 August 2026. This is a description of how the requirements map onto a shipment record, not legal or customs advice, and it does not cover every case: land border crossings, temporary exports and vehicles never titled in the United States all follow different paths. Regulations change. Verify your own obligations against the current text and with your customs counsel before relying on any of it.
