To align with Executive Order (EO) 14256, “Further Amendment to Duties Addressing the Synthetic Opioid Supply Chain in the People’s Republic of China as Applied to Low-Value Imports,” signed on April 2, 2025, at 5:00 p.m. ET today, April 22, 2025, U.S. Customs and Border Protection (CBP) will release the following updates to the CERT environment for testing:

Air Manifest:

New Air EDI validations for bills of lading with a CED line to release off the manifest (i.e., a disposition type 86 is posted to the bill).

• If the filer receives the following error codes for an air manifest shipment, it means that de minimis clearance will not be granted and the filer must take the appropriate action to bring the shipment into compliance with the requirements of EO 14256, as amended.
  • 181   COUNTRY OF ORIGIN CODE INVALID
  • 110   CBP ENTRY LINE IGNORED
  • 188      EXPRESS RECORD INCOMPLETE
• All messages will be sent in the form of an FER response message by ACE.

Truck Manifest:

• If the filer receives a message using the 470 (Inv Ctry of Orig for Shp) error code, it means that the shipment cannot receive de minimis clearance, and the filer must take the appropriate action to bring the shipment into compliance with EO 14256, as amended.
• For any bills filed prior to, but arriving after the actions in EO 14256, as amended, take effect, ACE will generate a 350 notification, using an existing disposition code for “Entry Not on File.” If the filer receives this message, it means that the shipment will be rejected at Primary and the filer must take the appropriate action to bring the shipment into compliance with EO 14256, as amended.

Manifest – All Modes:

• In situations where a manifest was filed before the actions outlined in EO 14256, as amended, become effective, but the conveyance will arrive after, the carrier will receive a 1M message notifying them that the shipment is not eligible for de minimis clearance, and the filer must take the appropriate action to bring it into compliance.
• For all modes where a 1C release message was already sent to the carrier/manifest filer, but the conveyance has not yet arrived, ACE will generate and send a 4E (cancel entry message) to cancel the release upon conveyance arrival.

Cargo Release/ Entry Type 86 (ET86): All Modes

• For ineligible ET86 transactions, ACE will return a “Reject” status with an additional error code of 318 – COUNTRY CODE INELIGIBLE FOR ET86 (SX error code message).
• In any instance where the ET86 is in released status before the arrival of the bill, the filer will receive an SO disposition message of “Release-Suspended” with an error code 33 – ET86 INELIGIBLE COUNTRY; CANNOT RELEASE.
• If these error messages are received, the filer must take the appropriate action to bring the shipments into compliance with EO 14256, as amended.

Shipments Entering via International Mail

• Guidance regarding shipments entering via international mail will be issued in a separate CSMS message.

Per Executive Order 14256, these changes are scheduled to be deployed to Production (PROD) at 12:01 a.m. ET on May 2, 2025.
