What is CSMS 64231666?

CSMS 64231666 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Update to the Automated Export System Commodity Filing Response Messages – Appendix A – Response Code 26C". 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 64231666 published?

CBP published CSMS 64231666 on February 25, 2025. 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.
