Protest Supporting Documentation Reminder

Plain-English explanation

CSMS 53441417 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on September 28, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "Protest Supporting Documentation Reminder". 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.

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.
