Plain-English explanation

CSMS 65313729 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on June 11, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "FDA Downtime June 21, 2025, 10 PM Eastern through June 22, 2025, 6 AM Eastern". 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.

Prior Notices can be submitted via the Automated Broker Interface (ABI)/Automated Commercial Environment (ACE); but will be queued during the outage window.

Please file your Prior Notices early to mitigate the impact of the delay. Please do not resubmit entries as this will cause additional delays For additional details, see Prior Notice Contingency Scenario 1: Prior Notice Contingency Scenario 1 For questions regarding Prior Notice, or with perishable shipments , please contact the FDA's Division of Targeting and Analysis (DTA), formerly DFDT.

Frequently asked questions

What is CSMS 65313729?

CSMS 65313729 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "FDA Downtime June 21, 2025, 10 PM Eastern through June 22, 2025, 6 AM Eastern". 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 65313729 published?

CBP published CSMS 65313729 on June 11, 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.
