Plain-English explanation

CSMS 64375535 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on March 11, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Quota Guidance: Proclamation 10896 of February 10, 2025, Adjusting Imports of Steel and Aluminum into the United States". 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.
