U.S. Customs Sets 45-Day Processing Timeline for Billions in Tariff Refunds
Washington, Thursday, 2 April 2026.
Businesses awaiting billions in tariff refunds face a 45-day processing window once the new U.S. Customs portal launches, offering vital clarity for corporate cash-flow planning in 2026.
The Architecture of the CAPE System
In late March 2026, U.S. Customs and Border Protection (CBP) provided critical updates to the U.S. Court of International Trade (CIT) regarding its Consolidated Administration and Processing of Entries (CAPE) system [2][6]. Designed to facilitate the return of tariffs levied under the International Emergency Economic Powers Act (IEEPA) during the Trump administration, the system is slated for an initial rollout in mid-April 2026 [1][5]. As of late March, the CAPE claim portal had reached 85 percent completion and entered active testing, up from 70 percent earlier in the month [6]. Other critical components, including mass processing and refund issuance, ranged between 60 and 80 percent complete [3][4].
Navigating the 45-Day Review Window
Once a business submits a declaration through the CAPE portal, CBP has established a timeline of up to 45 days to review and liquidate the identified entry summaries [1][2]. This 45-day window provides a measurable buffer between the portal’s launch and the actual distribution of funds, allowing the agency to conduct necessary compliance validations [5][6]. For corporate treasurers and supply chain managers, this timeline is a crucial metric for forecasting Q2 and Q3 2026 cash flows [GPT].
Legal Mandates and Subsequent Rollout Phases
The impetus for the CAPE system traces back to February 2026, when the Supreme Court ultimately deemed the emergency duties unlawful [1]. The high court, however, left the logistical burden of issuing refunds to lower courts and the administration [1]. Consequently, the CIT has been actively shaping the refund parameters. In a pivotal order on March 27, 2026, the CIT directed CBP to reliquidate and refund IEEPA tariffs even for entries that have reached final liquidation [3][5].
Strategic Imperatives for Affected Businesses
With billions of dollars in liquidity at stake, proactive compliance is essential. Although CBP intends to issue the vast majority of refunds electronically, data from late March 2026 indicated that 22 percent of importers subject to IEEPA tariffs had yet to complete the required enrollment for digital disbursements, meaning that 78 percent had successfully enrolled [1][2]. Businesses are urged to confirm their access to the Automated Commercial Environment (ACE) portal and finalize their Automated Clearing House (ACH) refund setups to avoid administrative bottlenecks [6].
