2025 Tuna Quota Proration

Plain-English explanation

CSMS 65761159 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on July 28, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "2025 Tuna Quota Proration". 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.

Frequently asked questions

What is CSMS 65761159?

CSMS 65761159 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "2025 Tuna Quota Proration". 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 65761159 published?

CBP published CSMS 65761159 on July 28, 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.
