Plain-English explanation

CSMS 65629394 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on July 14, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "UPDATE: Importer/Bond Query K1 Output Record". 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.

What is CSMS 65629394?

CSMS 65629394 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "UPDATE: Importer/Bond Query K1 Output Record". 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 65629394 published?

CBP published CSMS 65629394 on July 14, 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.
