Frequently asked questions

What is CSMS 38969041?

CSMS 38969041 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "REVISED: Updates to the ACE DIS Implementation Guide". 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.

CBP published CSMS 38969041 on July 19, 2019. 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.
