CSMS 65628258 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on July 14, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Initiation of Antidumping and Countervailing Duty Investigations: Steel Concrete Reinforcing Bar from Algeria, Bulgaria, Egypt, and the Socialist Republic of Vietnam (Vietnam)". 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.

CSMS 65628258 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Initiation of Antidumping and Countervailing Duty Investigations: Steel Concrete Reinforcing Bar from Algeria, Bulgaria, Egypt, and the Socialist Republic of Vietnam (Vietnam)". 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.
CBP published CSMS 65628258 on July 14, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.
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.
