CSMS # 66599946 - ACE Collections: Federal Register Notice Update Requiring Periodic Monthly Statement (PMS) Participants to Pay Supplemental Duty Bills Electronically via ACH

This message announces a change to the U.S. Customs and Border Protection’s (CBP) National Customs Automation Program (NCAP) test concerning Periodic Monthly Statements (PMS) to reflect that test participants must transmit electronic payment of supplemental duty bills resulting from an underpayment of estimated duties, taxes, and fees attributable to entries originally paid monthly through the PMS test. For PMS test participants, related supplemental duty bills may no longer be paid by check. Test participants must pay related supplemental duty bills by either ACH Debit or ACH Credit. ACH Debit payments will be submitted directly via Treasury’s Pay.gov system using the CBP Bill Payments form. To pay by ACH Credit, participants should contact ACH-CUSTOMS@cbp.dhs.gov to obtain specific instructions needed to pay a supplemental duty bill via ACH Credit. The modification announced via this test will become operational 60 days from the date of publication in the Federal Register (October 16, 2025).

The PMS Test Modification is available at: https://www.federalregister.gov/documents/2025/10/16/2025-19572/modification-of-the-national-customs-automation-program-test-regarding-periodic-monthly-statements
