CAIN (Customs Assigned Importer Number)

What is a CAIN?

A CAIN is a Customs Assigned Importer Number. If an importer is importing into the U.S. as a foreign importer of record and they do not have an EIN, Flexport can apply for a CAIN on their behalf.

Foreign importers of record importing into the U.S. without an EIN will need a CAIN.

How does a CAIN work?

A CAIN stands in for the Employer Identification Number (EIN), which the IRS issues to U.S. businesses. CBP uses the number to identify the importer on entry filings, so you'll use the same CAIN each time you import under that identity. A customs broker usually submits the application with details such as the business name and address, so have them ready.

Does a CAIN replace a customs bond?

No. A CAIN identifies you, and it doesn't cover duties. For most commercial shipments, importers still need a customs bond. Ask your broker which bond fits your import volume.
