Frequently asked questions

What is CSMS 45752501?

CSMS 45752501 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Customs Broker Notification and Request Documents sent to HQ via Email". 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 45752501 published?

CBP published CSMS 45752501 on January 19, 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.
