This is a very helpful resource for US importers, brokers and customs entry filers! Current messages posted by CBP @ CSMS Messaging Service – however more dated or ‘archived’ messages are difficult to find. Problem solved here as these links are captured and made available for immediate reference.

U.S. Customs and Border Protection’s (CBP’s) Cargo Systems Messaging Service (CSMS) is one of CBP’s methods for communicating to trade partners news and updates on our automated systems – namely the Automated Commercial Environment (ACE).

Participating Government Agencies (PGA’s) with CBP’s ACE program occasionally publish their own CSMS. These can be directive in nature while often illustrative on the agency’s intentions as to how these instructions are to be carried out.

Search if you need a specific topic – happy entry filing!
