The Automated Commercial Environment (ACE) system allows for interest-free, monthly payment of duties and fees which helps improve Importers’ cash flow. ACE filers who have been approved to participate in Periodic Monthly Statements (PMS) can pay duties for shipments entered or released during the previous calendar month. Below you will find the statement dates for 2026.

For more information on PMS, please see Participating in Periodic Monthly Statements Guide.

If you’re not signed up for PMS and would like to take advantage of its benefits, please contact us at hello@PMKIntl.com

For CPS ACE filers (U.S. Customs and Border Protection’s Automated Commercial Environment), the 11th workday is when the **Preliminary Periodic Monthly Statement (PMS)** is generated, showing what *will* be paid; the 15th workday is when the actual payment is debited via ACH for all entries from the prior month, followed by the **Final PMS**, consolidating the payments and confirming amounts. This system allows for interest-free, monthly payment of duties and fees, improving cash flow.
