CSMS 0079409 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on March 19, 2020. It carries the official CBP guidance brokers and importers must follow for the topic — "Cash deposit instructions for corrosion-resistant steel products from the Republic of Korea (A-580-878)". 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.

Scope text is authoritative; the HTS list is illustrative. Read scope, find past rulings, and file a 19 CFR 351.225 inquiry. Worked example on case A-570-106 (wooden cabinets from China).
