Impact of Vessel Schedule Changes on ISF

Immediate Update Requirement

The vessel name change does not impact the ISF on its own. Sometimes, however, the vessel change may cause the BL Number to change. If the BL Number changes, you must update the ISF as soon as possible to avoid a penalty. It’s also possible that the consolidator and container stuffing location might also change.

Types of Shipment Changes That Require Updates

Common Shipment Changes

• BL Number change.
• Consolidator change.
• Container Stuffing Location change.

Critical Information to Update

• BL Type.
• SCAC code.
• BL Number.
• Consolidator.
• Container Stuffing Location.

Compliance Timeline

Update Immediately Upon Notice

• File amendments as soon as you're notified of changes
• Don't wait for "final" confirmation if delays seem likely
• Multiple updates are acceptable if schedules continue to change

Maintain the 24-Hour Rule Remember that all ISF amendments must still be completed at least 24 hours before the vessel arrives at the first U.S. port.

Operational Benefits of Quick Updates
