It carries the official CBP guidance brokers and importers must follow for the topic — "30 Day Extension for Correcting Entries Subject to Third Country Case Numbers".

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.
