Notice of affirmative preliminary CVD determination and alignment of the final CVD determination with the AD investigation of silicon metal from Norway (C-403-807)

Plain-English explanation

CSMS 5273425 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on September 30, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Notice of affirmative preliminary CVD determination and alignment of the final CVD determination with the AD investigation of silicon metal from Norway (C-403-807)". It links to 1 AD/CVD case in Tandom's catalog. 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 5273425?

CSMS 5273425 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "Notice of affirmative preliminary CVD determination and alignment of the final CVD determination with the AD investigation of silicon metal from Norway (C-403-807)". 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 5273425 published?

CBP published CSMS 5273425 on September 30, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Which AD/CVD cases does CSMS 5273425 affect?

CSMS 5273425 references 1 AD/CVD case (C-403-807). The links on this page take you to each linked order with its current scope, rates, and history.

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.
