A '''Split Shipment''' occurs when a single PAPS entry (one shipment control number) is transported across the border in multiple loads due to shipment size or operational needs.
<div class="bc-2col">


Split shipments are arranged by the importer or customs broker, who obtains approval from the CBP port before the carrier begins moving the loads.

</div>
</div>


== How Split Shipments Work in ACE ==
</div> <div class="bc-note-table" style="margin-bottom: 30px;">
<h3>⚙️ One-Time Setup Required</h3>
<p>Before you can process split shipments, you must enable this setting in your account:</p>
<ol>
<li>Go to <strong>Account</strong> → <strong>Company Settings</strong>.</li>
<li>Under <strong>ACE Shipment Settings</strong>, set <strong>Allow ACE "Split Shipments"</strong> to <strong>Yes</strong>.</li>
<li>Click <strong>Save</strong>.</li>
</ol>
</div>


One master shipment is created first to represent the total quantity.
<div class="bc-card" style="margin-bottom:30px;">
Each physical load is then created as a split shipment segment linked to that master.
<h2>Phase 1: The Master Shipment</h2>
<p class="bc-subtle">The master shipment holds the total quantity for all segments combined. It is never attached to a manifest directly.</p>


Simple flow:
<div class="bc-grid">
<div>
<h3>1. Create the Shipment</h3>
<div class="bc-cleanlist">
* Navigate to <strong>ACE eManifests</strong> → <strong>Start New ACE Shipment</strong>.
* Enter the <strong>SCN (PAPS)</strong>, Shipper, Consignee, and Commodity.
* <strong>Crucial:</strong> Enter the <strong>Total Quantity</strong> for all loads combined.
* Click <strong>Save</strong>.
</div>
</div>
<div>
<h3>2. Send to CBP</h3>
<div class="bc-cleanlist">
* On the Shipment Details page, hover over <strong>Shipment Only Send to CBP</strong>.
* Select <strong>Send Unassociated Shipment</strong>.
* Wait for the status to change to <strong>Accepted</strong>.
</div>
</div>
</div>
</div>


Master shipment submitted → CBP accepts master → Split shipment segments created → Each segment synced as loads cross
<div class="bc-card" style="margin-bottom:30px;">
<h2>Phase 2: The Split Segments</h2>
<p class="bc-subtle">Each physical truck crossing the border gets its own "Segment" linked to the Master.</p>


== Enabling Split Shipments ==
<div class="bc-grid">
<div>
<h3>1. Start the Manifest</h3>
<div class="bc-cleanlist">
* Navigate to <strong>Start New ACE eManifest</strong>.
* Enter Trip #, Port, ETA, Truck, Trailer, and Driver.
* Click <strong>Save and Start New ACE Shipment</strong>.
</div>
</div>
<div>
<h3>2. Link the Segment</h3>
<div class="bc-cleanlist">
* Enter the <strong>Same SCN</strong> used for the Master.
* Check the box: ☑ <strong>Split Shipment Segment</strong>.
* Enter the quantity for <strong>this specific load only</strong>.
* Click <strong>Save</strong>. Commodity info will auto-fill from the Master.
</div>
</div>
</div>


Before creating split shipments:
<div class="bc-pro-tip">
<strong>Final Step:</strong> Return to the eManifest page and click <strong>Sync with CBP</strong>. The segment should be accepted within 30–60 seconds. Repeat this for every load until the total quantity reaches zero.

How to create master and split shipments

Watch the full walkthrough on creating Master and Split shipments.

What is a Split Shipment?

A Split Shipment occurs when a single PAPS entry (one SCN) is transported across the border in multiple loads.

Important Rule

Split shipments must be arranged by the importer or broker before moving loads. CBP approval is required.

The General Workflow:

  • Step 1: Create & Send the Master Shipment (Total Quantity).
  • Step 2: Wait for CBP Acceptance.
  • Step 3: Create Split Segments for each physical truckload.

⚙️ One-Time Setup Required

Before you can process split shipments, you must enable this setting in your account:

  1. Go to Account → Company Settings.
  2. Under ACE Shipment Settings, set Allow ACE "Split Shipments" to Yes.
  3. Click Save.

Phase 1: The Master Shipment

The master shipment holds the total quantity for all segments combined. It is never attached to a manifest directly.

1. Create the Shipment

  • Navigate to ACE eManifests → Start New ACE Shipment.
  • Enter the SCN (PAPS), Shipper, Consignee, and Commodity.
  • Crucial: Enter the Total Quantity for all loads combined.
  • Click Save.

2. Send to CBP

  • On the Shipment Details page, hover over Shipment Only Send to CBP.
  • Select Send Unassociated Shipment.
  • Wait for the status to change to Accepted.

Phase 2: The Split Segments

Each physical truck crossing the border gets its own "Segment" linked to the Master.

1. Start the Manifest

  • Navigate to Start New ACE eManifest.
  • Enter Trip #, Port, ETA, Truck, Trailer, and Driver.
  • Click Save and Start New ACE Shipment.

2. Link the Segment

  • Enter the Same SCN used for the Master.
  • Check the box: ☑ Split Shipment Segment.
  • Enter the quantity for this specific load only.
  • Click Save. Commodity info will auto-fill from the Master.

Final Step: Return to the eManifest page and click Sync with CBP. The segment should be accepted within 30–60 seconds. Repeat this for every load until the total quantity reaches zero.

Master vs. Segment: Key Differences

Feature Master Shipment Split Shipment Segment
Sequence Created First Created Second
Manifest Status Unassociated (Not on manifest) Attached to eManifest
