Can importers file directly through ABI?

No. ABI access requires a CBP-issued Filer Code, which is only granted to licensed customs brokers. Importers work through their broker.

What is the relationship between ABI and ACE?

ABI is the electronic interface that brokers use to interact with ACE programmatically. ACE is the broader portal; ABI is the automated pipeline into it.

What is ABI?

Automated Broker Interface — electronic system for customs brokers to file entries with CBP via software. In the context of U.S. customs and tariff recovery, understanding abi is essential for navigating the CAPE refund process and ensuring accurate duty assessment.

Definition

The Automated Broker Interface (ABI) is the electronic data interchange system that enables licensed customs brokers to file entries, transmit trade data, and communicate with CBP's systems programmatically. Rather than manually entering data into the ACE web portal, brokers use ABI-certified software to batch-process entry summaries, receive liquidation notices, and retrieve cargo status updates. ABI operates as the machine-to-machine layer on top of ACE, handling millions of entry transactions annually. Only CBP-licensed customs brokers with an assigned Filer Code can transmit via ABI.

How ABI Relates to Tariff Refunds

When your customs broker files a CAPE refund declaration, the data flows through ABI into CBP's processing systems. Tariffi prepares the declaration data; the broker's ABI-connected software transmits it. This separation ensures compliance with 19 U.S.C. section 1641 — only licensed brokers may transact customs business.

Example

A customs brokerage processes 5,000 entries per month using their ABI-certified software. When a client's IEEPA refund claim is ready, the broker's system transmits the CAPE declaration through ABI, receiving a confirmation number within minutes.
