ACE Shipment CSV Upload Feature (ACE Manifest)

🔖 This article is part of the BorderConnect ACE Manifest Guide and the BorderConnect Software User Guide

This guide explains how to import a large number of shipments into an ACE eManifest using BorderConnect’s CSV upload feature.

How to import shipments into an ACE eManifest

Selecting **Company Settings** from the Account menu

This feature is ideal when you have many shipments on one trip and want to avoid entering each shipment manually.

Overview

Using a BorderConnect CSV template, you can:

Upload shipments in bulk into a new or existing ACE eManifest
Automatically validate shipment data before it is saved
Resolve common formatting issues using clear import error messages

Step 1: Enable ACE Import Buttons

Enabling ACE import buttons in Company Settings

By default, shipment import buttons are disabled for many companies.

To enable them:

Go to Account on the top menu
Click Company Settings
Scroll to eManifest Preferences
Set Display ACE Import Buttons to Yes
Click Save

Once enabled, import controls will appear when creating or editing an ACE eManifest.

Step 2: Download the CSV Template

Before uploading, download the official BorderConnect template file:

ACE Shipment CSV Template

Important rules:

Do not rename, remove, or reorder the column headers
Save the file as CSV format before uploading
CSV is required even if you edit it using Excel or another spreadsheet tool

Step 3: Fill Out the CSV File

The template includes columns for:

Shipment control number and shipment type
Shipper and consignee details
Commodity description, value, quantity, weight, and units
Country of origin and additional shipment fields

Importing 10,000 or More Shipments

Importing 10,000 or more shipments into an ACE Manifest

BorderConnect supports importing up to 9,999 shipments per manifest by default.

If you need 10,000 or more shipments on one trip, the process is:

Create multiple manifests and import up to 9,999 into each
Use Link Shipments to Trip to link shipments back to the original manifest for CBP processing

High Volume Workflow

Step	What You Do
1	Create the original manifest, import the first batch, save and view trip details
2	Create a second manifest with a modified trip number (example: add B)
3	Enable Show All Fields and set Link Shipments to Trip to the original trip
4	Import the second batch and save
5	Repeat for additional batches (example: add C, D) if required
6	Send the first manifest to CBP and wait for acceptance
7	Send each linked manifest to CBP using Link Shipments to Trip transmission

Sending Link Shipments to Trip to CBP

Common Import Errors

This section lists common CSV upload errors and how to correct them.

Shipment Control Number Errors

Can't perform import since AUTOFILL shipment numbers are combined with explicitly stated shipment control numbers.

Cause:

Some rows use SCAC+AUTOFILL and others use manual SCNs

Fix:

Use AUTOFILL for all rows or remove AUTOFILL entirely

Also check for blank rows containing only commas near the bottom of the file.

SCAC Code [AAA5] is invalid. Must be 4 alphanumeric characters. [AAA5459071]

Cause:

SCAC is not exactly 4 characters

Fix:

Correct SCAC to 4 alphanumeric characters

Shipment Control Number is invalid, it must be 8-16 alphanumeric characters with no spaces and letters must be uppercase. [AAAA545907321321321131]

Cause:

SCN too long or invalid format

Fix:

Ensure 8 to 16 characters, uppercase, no spaces

Shipment Type Errors

Shipment Type [SECTION 321] is invalid [AAAA5459071]

Cause:

Incorrect value format

Fix:

Use the valid value exactly, such as SECTION_321 if applicable for your template version, or match the official list shown above

Shipper Errors

Province of Loading code [BX] unrecognized. [AAAA5459071]
OR
Province of Loading code [British Columbia] unrecognized. [AAAA5459071]

Fix:

Use province/state abbreviations only, example: BC

Shipper Name [...] invalid. Must be between 1 and 60 characters, with no accents or other invalid characters. [AAAA5459091]

Fix:

Shorten the name to 60 characters or fewer

Shipper Canadian Postal Code [VSS 1A1] invalid. [AAAA5459219]

Fix:

Ensure valid Canadian postal code format, example: V5S 1A1

Consignee Errors

Consignee State [California] is invalid or does not match with country [US]. [AAAA5459219]

Fix:

Use 2-letter U.S. abbreviations, example: CA

Consignee U.S. Zip Code [4321] invalid. [AAAA5459219]

Fix:

Use 5 digits or ZIP+4 format

Note: Spreadsheet tools can remove leading zeroes. A ZIP like 04321 may become 4321 and fail validation.

A common workaround is to format the cell as text or use: ="04321"

Commodity Errors

Unknown packaging unit [box]. [AAAA5459219]

Fix:

Package codes must match exactly, example: BOX

Shipment commodity weight is invalid. It must be numeric [0.63]

Fix:

Weight must be a whole number, round up to 1 if under 1

Commodity weight unit [POUNDS] is invalid. [AAAA5459219]

Fix:

Use valid units: L, LB, LBS, or LBR
