Frequently asked questions

What is CSMS 65323831?

CSMS 65323831 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "REMINDER: ACE Reports Webinar Set for June 17, 1:00 – 2:30 p.m. ET". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 65323831 published?

CBP published CSMS 65323831 on June 12, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
