From US Customs’ January 2017 ACE Monthly Trade Update:

Below are the preliminary (11th workday) and final (15th workday) dates for Periodic Monthly Statement (PMS). The latest date in which the “Preliminary” PMS can be requested to generate is the 11th workday of the month.

However, some companies do request their preliminary PMS to generate before the 11th workday. “Final” is the due date for the preliminary PMS. This date is also when ACE sends the Periodic Daily Statement (PDS) payment authorization message (PN Transaction) for the PMS to the website.

US Customs published Cargo Systems Messaging Service (CSMS) message #17-000009 to announce the postponement of the January 14, 2017 ACE deployment. A new date will be announced in the near future.

Effective with the rescheduled date for this deployment, the final PMS will be generated to the trade community in two or three business days instead of the current one day issuance in ACE and Automated Commercial System (ACS). In ACE, the final PMS has to date been generated the day after CBP sent the PN authorization message to and not when the payment was transferred to CBP.

Additionally, please keep in mind that ACE Reports may not generate quickly on days when preliminary and final PMSs are generated. CBP suggests that you run and/or schedule your PMS reports during non-peak business hours and/or on days when they are not due.

For more information concerning statement processing, please review the Statements in ACE Information Notice, the Periodic Monthly Statement User Guide posted on the “ACE and Automated Systems” and “ACE Portal Training Resources” pages of Questions concerning participation in Periodic Monthly Statement should be directed to the CBP Revenue Division. Users can send an email to or contact the ACE Periodic Monthly Statement Payment Help Desk at 317-614-4545.
