CSMS # 65085008 - ACE Air, Ocean and Rail CAMIR New De Minimis Notification Code

The ACE Air Import Manifest Appendix A and the ACE Ocean/Rail Import Manifest Appendix D implementation guides have been updated with the following notification code:

4M - Withhold Entry Release - De Minimis Met

If a filer receives this code, it means that the shipment’s value exceeds the de minimis threshold. Accordingly, the filer will need to request a different type of clearance.

Please note that this code is part of the Section 321 – Does Not Exceed $800 in Aggregated Shipments enhancement in ACE and is not yet deployed in the CERT or Production environment. The CERT and Production deployment dates will be announced in a later CSMS message.

Please reach out to your Client Representative if you have any technical-related questions.
