Making Changes to ACI eManifests
A guide to updating, correcting, and removing shipments from submitted manifests before arrival.
Overview
This guide explains how to make changes or corrections to an already-submitted ACI eManifest using BorderConnect.
This assumes that:
- The eManifest has already been transmitted to CBSA.
- The driver has not yet arrived at the border.
- The manifest is currently "On File with CBSA."
Important: Once the driver arrives at the border, most changes are no longer permitted electronically. Always complete updates before arrival.
How Changes are Processed
The method used to update an ACI eManifest depends on what information is being changed.
| Type of Change | Action Required |
|---|---|
| Trip Details (Port, ETA, Trip #) | Edit -> Sync with CBSA |
| Truck / Trailer / Seals | Edit -> Sync with CBSA |
| Shipper / Consignee | Edit -> Sync with CBSA (or Change Shipment Request) |
| Cargo Control Number (CCN) | Edit -> Sync with CBSA |
| Add/Remove Shipments | Sync (plus Cancel Request for removed cargo) |
Step-by-Step: Syncing Changes
Most updates are transmitted using Sync with CBSA, which automatically resubmits the affected data for acceptance.
1 Make the Change
Make all required edits first. If multiple changes are needed, complete all edits before syncing.

- Port/ETA: Click Edit (top-left), update the details, and Save. Select Yes to update all attached shipments.
- Truck/Trailer: Click Remove to detach, then use Quick Assign to add the correct vehicle.
- Seals: Click View on the truck/trailer, add the seals, and return to the manifest.
- Shipment Data: Click View on the shipment to edit Shipper, Consignee, or Commodities.
2 Transmit to CBSA
Once edits are complete, send the update.

- Sync with CBSA: The primary button for almost all changes.
- Send Change Shipment Request: Use this only if changes apply to a single shipment (e.g., just correcting a weight).
3 Verify Acceptance
After syncing, the status will briefly show "Transmitted to CBSA." Wait for it to return to On File with CBSA or On File with Transaction Numbers.
Specific Change Scenarios
Changing Trip or Cargo Numbers
These updates do not require recreating the manifest, but they do require a sync.
1. Trip Number: Click Edit on the manifest header, update the Trip Number, Save, and click Sync with CBSA. 2. CCN: Edit the shipment, update the Cargo Control Number, Save, and click Sync with CBSA.
Adding a Shipment
1. Click Create New Shipment on the manifest. 2. Enter all required shipment data. 3. Click Sync with CBSA. 4. Wait for the sync to complete (this may take up to 10 minutes).
Removing a Shipment
Removing a shipment is a 3-step process to ensure it is fully cleared from CBSA's system.

Step 1: Detach
Click Detach next to the shipment on the manifest to remove it from the trip.
Step 2: Sync
Click Sync with CBSA on the original manifest to tell Customs the shipment is no longer on that truck.
Step 3: Cancel
The shipment still exists in CBSA's system as an orphan. You must delete it.
1. Search for the shipment using the ACI Shipment Search Page. 2. Click View. 3. Under "Send to CBSA", select Send Cancel/Delete Shipment Request.
