U.S. Customs and Border Protection has finalized a rule requiring advance electronic export manifests in the Automated Commercial Environment for all rail cargo departing the United States for Canada or Mexico.
The rule takes effect October 26, 2026. CBP will begin enforcement on October 26, 2027, providing the trade community one year to prepare for mandatory compliance.
The requirements affect more than rail carriers. Exporters, freight forwarders, NVOCCs, customs brokers, ABI filers, and other parties involved in cross-border rail shipments may transmit certain information and will need to coordinate how required data is collected, verified, and submitted.
What the Final Rule Requires
The new regulation replaces paper export manifests with an electronic export manifest, or EEM, transmitted through ACE.
It applies to all cargo transported by rail from the United States to Canada or Mexico, including shipments for which Electronic Export Information may not otherwise be required.
This is a significant expansion because EEI is generally required only when the value exceeds $2,500 per Schedule B number or when another filing requirement applies. Exports to Canada are also commonly exempt from EEI requirements unless they involve controlled goods or are being transshipped to another destination.
The new rail manifest is separate from EEI and is intended to provide CBP with advance information for every outbound rail shipment.
Initial Information Is Due 24 Hours Before Departure
Seven initial data elements must be transmitted as early as practicable, but no later than 24 hours before the train’s scheduled departure from the designated U.S. port of export:
- Bill of lading number
- Total quantity
- Total weight
- Cargo description
- Shipper name and address
- Consignee name and address
- Employer Identification Number, Internal Revenue Service number, or CBP-assigned number
An Automated Export System Internal Transaction Number or Foreign Trade Regulations exemption or exclusion code is a conditional element. It must be transmitted when applicable and as soon as it becomes available.
The deadline is tied to the train’s scheduled departure from the designated U.S. port of export. It is not based on departure from an inland rail yard or the moment the train physically crosses the border.
Remaining Information Is Generally Due Two Hours Before Departure
The remaining cargo and transportation data must generally be transmitted no later than two hours before the train departs the U.S. port of export.
The rule also establishes requirements for empty rail cars and containers, corrections, cancellations, split shipments, and responses to CBP instructions.
Cargo subject to a “do not load” or hold instruction cannot proceed contrary to that instruction. The party transmitting a particular set of data is also responsible for responding to questions, holds, or other directions resulting from CBP’s review of that information.
Who Is Responsible for Filing?
The outbound rail carrier is responsible for transmitting transportation data and empty-container information.
The carrier is also responsible for the initial filing and remaining cargo data if no other eligible party elects to transmit it.
Other parties eligible to transmit certain data include:
- The U.S. Principal Party in Interest
- The Foreign Principal Party in Interest
- Authorized agents
- Customs brokers
- ABI filers
- Freight forwarders
- NVOCCs
- Other parties with direct knowledge of the export information
CBP clarified that transmitting rail EEM data for purposes of complying with the rule does not itself constitute customs business.
However, the ability of multiple parties to file does not eliminate the need for clearly assigned responsibilities. If another party does not transmit the required information, the party arranging for or delivering the cargo to the outbound carrier must provide the necessary data to the carrier.
A Bond Will Be Required
The party transmitting rail export manifest information must have an applicable CBP bond.
Depending on the filer, that may include a basic custodial bond or an international carrier bond. Companies considering whether to transmit information directly should review their existing bond structure and determine whether changes will be needed before enforcement begins.
The Voluntary Rail Test Will End
CBP has operated an ACE Export Manifest for Rail Cargo Test since 2015. The test will end when the final rule becomes effective on October 26, 2026.
Although CBP will not begin enforcement until October 26, 2027, companies should not treat the intervening year as a reason to delay preparation. Participants will need time to update systems, map data sources, establish filing responsibilities, test transmissions, amend procedures, and train employees.
What Rail Exporters and Logistics Providers Should Do
Companies involved in U.S. rail exports should:
- Identify all shipments moving by rail to Canada or Mexico.
- Determine who will transmit the initial, cargo, transportation, and empty-container data.
- Document responsibilities among exporters, carriers, forwarders, brokers, and other service providers.
- Map the source of each required data element.
- Confirm that information can be provided before the 24-hour and two-hour deadlines.
- Review contracts and operating procedures for inaccurate or late data.
- Evaluate ACE connectivity and filing-system requirements.
- Review CBP bond coverage.
- Establish procedures for amendments, cancellations, split shipments, and empty rail cars.
- Assign personnel to monitor and respond to CBP holds and instructions.
- Test workflows well before enforcement begins on October 26, 2027.
The rule creates a longer planning window than many recent customs changes, but implementation will require coordination across multiple parties. Exporters should begin discussing the requirements with their rail carriers and logistics providers now.
