It carries the official CBP guidance brokers and importers must follow for the topic — "Generalized System of Preferences Updates".

CSMS 45035166 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Generalized System of Preferences Updates". 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.

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.
