Frequently asked questions

What is CSMS 46558894?

CSMS 46558894 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "ACE CERTIFICATION Scheduled Maintenance, Wed. March 10, 2021 @ 5pm ET to 8pm 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 46558894 published?

CBP published CSMS 46558894 on March 10, 2021. 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.
