What is the latest time that manifest data for rail shipments must be received by CBP before arrival?

Manifest data for rail shipments must be submitted to Customs and Border Protection (CBP) at least 2 hours before the train arrives at a U.S. port of entry. This regulation is in place to ensure that CBP has sufficient time to process the data and conduct any necessary risk assessments or inspections prior to the arrival of the shipment. By requiring this advance notice, CBP can enhance border security and facilitate smoother import procedures.

The 2-hour requirement allows for effective coordination and enables customs officials to address any potential issues or concerns related to the shipment. This timeframe is designed to balance the need for timely information with operational practicality for rail carriers. As such, understanding this timeline is crucial for compliance with CBP regulations and for planning shipments appropriately.
