Plain-English explanation

CSMS 42987955 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on June 10, 2020. It carries the official CBP guidance brokers and importers must follow for the topic — "ACE System Failures from 6/9 11:48 PM to 6/10 00:34 AM". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

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.
