Plain-English explanation

CSMS 48629769 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on June 29, 2021. It carries the official CBP guidance brokers and importers must follow for the topic — "Error 691 LIC/CERT/PERM NUMBER UNKNOWN on valid steel and aluminum license numbers". 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.

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.
