CSMS 2325403 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on November 21, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "Statutory injunction on certain vertical shaft engines between 99cc and up to 225cc, and parts thereof from the People's Republic of China for Chongqing Zongshen General Power Machine Co. and other cross-owned companies for the period 05/26/2020 through 08/23/2020 (C-570-125), court number 21-00264". 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.

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.
