Plain-English explanation

CSMS 4163406 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on June 11, 2024. It carries the official CBP guidance brokers and importers must follow for the topic — "Creation of third-country case numbers for aluminum extrusions from the People's Republic of China (A-570-158) completed/assembled in Canada (A-122-158)". It links to 2 AD/CVD cases 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.

Message body

Full text as published by U.S. Customs and Border Protection

This is an informational message. No action is required. 1. AD/CVD investigations generally cover products from a particular country. In some cases, however, products from the country subject to the AD/CVD investigation may undergo completion or assembly in a third country prior to export or sale to the United States. The products may remain subject to the AD/CVD investigation despite the completion or assembly that occurs in the third country. However, for CBP purposes, the country of origin for such products may be the third country where the completion or assembly occurred. For technical reasons, the country of the AD/CVD case number must match the CBP country of origin in the entry summary documentation. Accordingly, Commerce establishes third country AD/CVD case numbers that match the CBP country of origin for CBP purposes. 2. The merchandise covered by this investigation is described in message number 4135421 dated 05/14/2024. 3. Effective 05/07/2024, Commerce established a third-country case number to allow aluminum extrusions completed/assembled in Canada to be properly reported as subject to the less-than-fair-value investigation of aluminum extrusions from the People's Republic of China (A-570-158) upon entry. Third Country: Canada Case Number: A-122-158 Producer and/or Exporter: All Others Case Number: A-122-158-000 Cash Deposit Rate: 365.19 % The third country case numbers above have been assigned for CBP purposes. 4. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIV:HS). 5. There are no restrictions on the release of this information. Alexander Amdur

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.
