What is EIN?

Employer Identification Number — the 9-digit IRS tax ID used to identify importers in CBP systems. In the context of U.S. customs and tariff recovery, understanding ein is essential for navigating the CAPE refund process and ensuring accurate duty assessment.

Definition

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. In the customs context, the EIN serves as the primary identifier for importers in CBP's systems. Combined with a two-digit suffix, it forms the Importer of Record (IOR) number. The EIN is required on entry documentation, bond applications, and virtually all interactions with CBP. Sole proprietors without employees may use their Social Security Number, but most commercial importers use their EIN.

How EIN Relates to Tariff Refunds

The EIN is the key identifier linking your import entries to your business for CAPE refund purposes. When Tariffi analyzes your ES-003 data, the EIN (appearing as part of the IOR number) is used to identify all entries belonging to your company. The CAPE declaration includes the EIN to ensure refunds are routed to the correct entity.

Example

Company XYZ has EIN 12-3456789 and IOR number 12-3456789-00. When Tariffi ingests their ES-003, it filters entries by this IOR number and finds 200 entries eligible for IEEPA refund, all tied to the same EIN.
