How to use the ACE portal to gather data for IEEPA tariff refunds

Importers hoping to recover IEEPA-related tariffs face significant challenges. The Automated Commercial Environment (ACE) portal is currently the only avenue to a refund, yet many companies lack access and others find the interface difficult to navigate. Understanding how to use ACE portal reports for IEEPA tariff refunds is a critical first step in preparing for recovery.

Early preparation matters. A surge in filings is expected when U.S. Customs and Border Protection (CBP) launches its CAPE (Claims and Processing Engine) system. While courts have pushed for refunds to move forward, CBP is still working on a system capable of handling the volume. For now, importers are operating within these constraints.

This guide explains how to confirm access, validate account configuration and gather the data required to support an IEEPA tariff refund.
