It carries the official CBP guidance brokers and importers must follow for the topic — "Request for Participants: Trade Support Network (TSN) Working Group: Ocean AMS Streamlining".

Frequently asked questions

What is CSMS 55296642?

CSMS 55296642 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Request for Participants: Trade Support Network (TSN) Working Group: Ocean AMS Streamlining". 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 55296642 published?

CBP published CSMS 55296642 on February 28, 2023. 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.
