TCCU Published Message No. TCC18-065 notifying clients they will be streamlining the TCCU'S bulletins for scheduled maintenance outages.  This change will provide users who are subscribed to the service with additional transparency related to the eManifest Portal, Electronic Data Interchange,  CCS / CADEX and the Single Window Initiative systems especially since the systems interact with each other and a scheduled maintenance of one system may effect the functionality of another system.  (Carrier systems {eManifest Portal, EDI (eManifest & RNS)}, Customs Broker / Importer Systems {EDI, CADEX, SWI}).
