How to receive CSMS Messages
This article describes how you can receive the CSMS messages which replaced Customs' old Administrative Messages system.
Subscribing to emails
Visit https://public.govdelivery.com/accounts/USDHSCBP/subscriber/new?qsp=938 and click Submit to see list of possible message types you can subscribe to.
Generally speaking all you need is the “Trade” messages. You can check “Trade” and all sub categories will be checked and you can then review those categories and uncheck those you don’t want.
Browsing past message
You can browse all past administrative and current CSMS messages by visiting http://apps.cbp.gov/csms/csms.asp
