Plain-English explanation

CSMS 51041050 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on February 16, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "Temporary PAPS Entries at Windsor Tunnel No Longer Accepted". 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.

CSMS #51041050 - Temporary PAPS Entries at Windsor Tunnel No Longer Accepted U.S. Customs and Border Protection sent this bulletin at 02/15/2022 10:10 PM EST Cargo Systems Messaging Service CSMS #51041050 - Temporary PAPS Entries at Windsor Tunnel No Longer Accepted As a result of the traffic issues created by the "Freedom Convoy" blocking commercial traffic from crossing the Ambassador Bridge, the Port of Detroit allowed "PAPS" (Formal Entry) shipments to be diverted to the Detroit Windsor Tunnel for processing. This diversion, while necessary, created significant system, procedural and examination challenges for the trade, stakeholders and CBP to overcome. As of 0001 hours on February 14, 2022 the Ambassador Bridge reopened with both inbound and outbound traffic flowing freely. This opening allows commercial traffic to return to normal processing and for the challenges incurred at the Detroit Windsor Tunnel to be eliminated. That said, as of 0800 hours on February 16, 2022, the Detroit Windsor Tunnel will no longer accept "PAPS" (Formal Entry) shipments and will return to normal processing of very limited commercial traffic of "Brass" and "Informal" Entries.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. 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.
