  Title: January 1: Manifest required for Section 321 truck shipments
  Date: 12/12/2018 12:45:44 PM
  To: ACE Portal Accounts, Truck Manifest
  Related: 18-000656

Beginning January 1, 2019 all commercial truck shipments containing Section 321 merchandise 
will be required to file an advance electronic manifest in accordance to the guidelines specified in the Trade Act of 2002.

Shipments qualifying for Section 321 release were exempt from the electronic manifest filing requirement due to a policy decision made by CBP during the implementation of the Trade Act of 2002.

The rise in eCommerce combined with the increase in the De Minimis value, has resulted in a significant growth in shipments being manifested and released under Section 321.

The lack of an electronic manifest eliminates CBP’s ability to conduct a risk assessment or perform advance targeting within the Automated Targeting System (ATS), results in slower processing times and longer wait times.

Beginning November 26, 2018, CBP began a phased approach for non-compliance with conveyances being referred to secondary for processing. Then Starting January 1, 2019, carriers which make no attempt to comply with the electronic manifest requirement may be subject to a monetary penalty ($5000 for the first offence and $10,000 for subsequent offences).

In order to file electronic manifests you will need a 4-letter Standard Carrier Alpha Code (SCAC) issued by the National Motor Freight Traffic Association (NMFTA). If you do not already have a SCAC, see the NMFTA website at

Once you have a SCAC, there are three ways to file required electronic manifests:

1. Apply for a free ACE Portal carrier account for filing online directly to CBP.
See application information at The application itself is at

Because it supports so many different account types, the ACE Portal application form can be confusing. To apply for a carrier account:
·Complete the top of Section A.
·Skip parts 1, 2 & 3, and most of part 4.
·In part 4d (Truck Carrier) just select P (Primary) and enter your SCAC in the first SCAC field.
·If you do not have a Type 2 bond, enter “NA” in the first “Activity Type 2 Bond Number” and “IR Number for Type 2 Bond” fields.
·Do not include part 4e Driver/Crew information.
·Then complete Sections B-D, providing your business address in the appropriate part of Section B.

If you need additional assistance with completing or filing the application, please contact our ACE Support group at or 866-530-4172.
