CAIN (Customs Assigned Importer Number)

Definition

The Customs Assigned Importer Number (CAIN) is a specific identification code issued by U.S. Customs and Border Protection (CBP). It serves as the official identifier for foreign companies that act as the Importer of Record (IOR) for shipments entering the United States, particularly when that company does not possess a U.S. Employer Identification Number (EIN).

Core Function and Necessity

Any entity importing commercial goods into the U.S. must have a valid importer identification number to successfully clear customs. If the Importer of Record is a foreign entity without a U.S. physical presence or tax obligations requiring an EIN, the CAIN is mandatory for the formal customs entry process.

This application process is typically managed by a licensed customs broker or logistics partner on behalf of the foreign importer. This streamlined approach prevents unnecessary customs delays and ensures the lawful entry of commercial goods.

Expert Guidance

Foreign importers must initiate the CAIN application early in the logistics planning process. Failure to secure this number will halt the importation process at the border.

Key Takeaways

• CAIN is required for foreign Importers of Record without an EIN.

• It ensures compliance with CBP entry procedures.

• Application is typically handled by the importer's customs broker or logistics provider to expedite clearance.
