Importers could begin receiving IEEPA tariff refunds as early as late April 2026 through CBP's new automated CAPE system, but must prepare now for electronic-only payments.
Importers who paid billions in now-invalidated IEEPA tariffs could begin receiving refunds as early as late April 2026, as U.S. Customs and Border Protection races to complete an automated refund system following a Supreme Court ruling that struck down the duties.
CBP is targeting April 20, 2026, for the launch of its new Consolidated Administration and Processing of Entries (CAPE) system, which will handle the massive task of processing approximately $165 billion in refunds to importers who paid the now-unlawful tariffs.
The timeline stems from the Supreme Court's February 20, 2026 ruling that struck down IEEPA tariffs in a 6-3 decision, finding that the International Emergency Economic Powers Act does not authorize presidential tariff imposition. The Court of International Trade followed up on March 4, 2026, with an order requiring CBP to liquidate and reliquidate entries without the IEEPA duties.
The ruling affects tariffs collected under multiple trade disputes, creating what may be the largest customs refund process in U.S. history. CBP announced the 45-day target timeline for CAPE system completion on March 6, 2026, putting the launch deadline at April 20.
Once operational, the CAPE system will follow a streamlined four-step process:
Refunds will include interest calculated at the corporate rate of 6%, significantly increasing the total payout beyond the $165 billion in principal duties collected.
Importers must prepare now for the electronic-only refund system. CBP moved to all-electronic refunds as of February 6, 2026, eliminating paper checks entirely. Companies that haven't enrolled in CBP's ACH system will be unable to receive their refunds when the CAPE system launches.
The enrollment process can take several weeks, making immediate action critical for importers who want to receive refunds as soon as they become available.
The first phase of CAPE will exclude several categories of complex entries, including:
Importers with these entry types will need to wait for later system phases or pursue alternative refund mechanisms. CBP has not announced specific timelines for handling these excluded categories.
Importers whose entries were already liquidated before the Supreme Court ruling face additional complexity. These companies may need to file separate protests to preserve their refund rights, even as they participate in the CAPE system process.
The protest requirement adds another layer of deadline pressure, as protest periods are typically limited and missing them could forfeit refund eligibility entirely.
As of March 19, 2026, CAPE system components ranged from 45% to 80% complete according to industry sources familiar with the development process. While CBP maintains confidence in the April 20 target date, the compressed timeline and system complexity create inherent risks of delays.
Any delay in CAPE's launch would push refund payments further into 2026, potentially affecting importers' cash flow and business planning.
Importers should take immediate steps to prepare for CAPE system availability:
The IEEPA refund process is unprecedented in scale, and the automated CAPE system represents CBP's attempt to manage the complexity efficiently. For importers, the April timeline creates both opportunity and urgency to ensure they're positioned to claim their share of the $165 billion refund pool.
