This notice announces the planned implementation of the Advance Commercial Information (ACI) initiative, and provides information on the effective date and details of the initiative, including the 24-hour advance cargo notification rule announced in April 2003. ACI will be implemented in phases, beginning with the marine mode on April 19, 2004. The implementation schedule for other modes rail, air and highway will be announced in a future Customs Notice. There will be no changes to secondary cargo reporting procedures for marine shipments (e.g., house-bills, re-manifests, abstracts) during this phase of ACI implementation. Implementation of mandatory electronic secondary cargo reporting procedures will be phased in, subsequent to or concurrent with the implementation of other modes.
