CSMS 39344431 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (system update), published on August 14, 2019. It carries the official CBP guidance brokers and importers must follow for the topic — "Updated ACE CATAIR Appendix P – e214 FTZ Error Codes now posted to CBP.gov". 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.
