Plain-English explanation

CSMS 65494504 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on June 30, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "U.S. Food and Drug Administration (FDA) Non". 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.
