Plain-English explanation

CSMS 45309115 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on December 29, 2020. It carries the official CBP guidance brokers and importers must follow for the topic — "Harmonized System Update (HSU) 2009 created on December 29, 2020".

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.
