It carries the official CBP guidance brokers and importers must follow for the topic — "REMINDER UFLPA Region Alert Deployment to PROD on 3/18/23".

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.
