It carries the official CBP guidance brokers and importers must follow for the topic — "Immediate Delivery Procedures Updated in the CATAIRs and Error Dictionaries".

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.
