What is the name of the U.S. regulation requiring importers to submit cargo information 24 hours before loading on a vessel?

The U.S. regulation requiring advance cargo information is called the Importer Security Filing.

The filing is commonly known as ISF or “10+2.” It applies to qualifying cargo arriving in the United States by vessel and requires the importer or an authorized agent to transmit specified information electronically to U.S. Customs and Border Protection.

For most covered shipments, key importer data must be submitted no later than 24 hours before the cargo is laden aboard the vessel at the foreign port. The name “10+2” refers to 10 importer-provided data elements plus two carrier data elements: the vessel stow plan and container-status messages.

A common mistake is to call the filing the 24-Hour Manifest Rule. That is a related advance-data requirement, but the Importer Security Filing is the importer-focused submission. Bulk cargo and certain breakbulk shipments receive specific exceptions or different timing rules.
