CSMS 40531423 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Harmonized System Update (HSU) 1918 created on October 31, 2019". 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.

When was CSMS 40531423 published?

CBP published CSMS 40531423 on November 6, 2019. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

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.
