For ocean shipments inbound to the U.S., when must an ocean carrier need detailed B/L instructions?

The ocean carrier is required to have detailed Bill of Lading (B/L) instructions at least two days prior to loading to ensure that proper documentation and vessel space can be allocated for the upcoming shipment. This timeframe allows the carrier to prepare and manage logistics effectively, adhering to both regulatory requirements and best practices for shipping operations. Having the instructions in advance is essential for the preparation of accurate shipping documents and proper compliance with U.S. Customs and Border Protection regulations, which helps to prevent delays or issues during the importation process. By requiring the detailed instructions two days ahead of loading, the carrier can also coordinate with other parties involved in the shipping process, maintain efficient operations, and provide adequate notification of space availability on their vessels.
