Watch: How to create Master & Split shipments.
Overview
A Split Shipment is when one PAPS entry (one SCN) is transported in multiple loads.
Important Rule
Split shipments must be approved by the Port and arranged by the broker before the driver moves.
The Process:
- Master Shipment: Holds the total quantity.
- Split Segments: Individual loads linked to Master.
- Sync: Each load is synced as it crosses.
First Time Setup: Go to Account → Company Settings and set Allow ACE "Split Shipments" to Yes.
Step 1: The Master Shipment
The Master Shipment is a container for the total quantity. It is never attached to a manifest.
Create
- Go to ACE eManifests → Start New ACE Shipment.
- Enter the SCN (PAPS) and Shipper/Consignee details.
- Enter the Total Quantity for all loads combined.
- Click Save.
Send
- On the Shipment Details page, hover over the "Send to CBP" menu.
- Click Send Unassociated Shipment.
- Wait for the status to change to Accepted.
Step 2: The Split Segments
Create a separate manifest for every physical truckload crossing the border.
Create Manifest
- Start a New ACE eManifest.
- Enter Trip, Port, Truck, and Driver info.
- Click Save and Start New ACE Shipment.
Link Segment
- Use the Same SCN as the Master.
- Check the box: ☑ Split Shipment Segment.
- Enter quantity for this load only.
- Click Save (Commodity info auto-fills).
Final Step: Go back to the eManifest and click Sync with CBP. Repeat this for every load until the total quantity is zero.
