For all the aggressive trade actions implemented in 2025 and 2026, the administration recently hit a massive, unexpected roadblock at the highest level of the U.S. judicial system.
When the Supreme Court struck down the administration’s sweeping use of the International Emergency Economic Powers Act (IEEPA)—most notably the 20% baseline “Fentanyl” tariffs—it didn’t just halt a major policy tool. It triggered an unprecedented logistical nightmare: the federal government now owes importers billions of dollars in unlawfully collected duties.
Here is a look at the resulting scramble, the rollout of the new refund infrastructure, and what businesses need to do to get their money back.
The Fall of the IEEPA Tariffs
The administration had leaned heavily on IEEPA to bypass the traditional, multi-year Section 301 investigation process, using national emergency declarations to slap immediate 20% baseline tariffs on massive swathes of imports.
However, in a landmark ruling earlier this year, the Supreme Court determined that the executive branch had overstepped its statutory authority. The Court ruled that using IEEPA for broad, non-specific economic grievances (rather than direct national security threats) was unconstitutional.
Virtually overnight, the 20% tariffs were invalidated. But the ruling left a massive lingering question: What happens to the billions of dollars already collected?
The Court mandated that U.S. Customs and Border Protection (CBP) return the funds to the importers of record. What followed has been described by trade professionals as the largest bureaucratic bottleneck in CBP history.
Enter the CAPE Portal
To handle the tidal wave of refund requests, CBP rapidly deployed the Customs Automated Portal for Electronic-refunds (CAPE).
Prior to CAPE, duty refunds were largely handled through archaic Post Summary Corrections (PSCs) or formal protests via the ACE (Automated Commercial Environment) system—a process that would have collapsed under the weight of the IEEPA refunds.
The CAPE portal was designed to be a streamlined, standalone system specifically for reclaiming invalidated IEEPA duties. However, the rollout has been anything but smooth.
The Catch: Strict Rules for Clawing Back Your Money
If your business paid IEEPA tariffs between 2025 and the Supreme Court ruling in 2026, the money is legally yours—but CBP isn’t going to just mail you a check. You have to fight for it through the CAPE portal, and the rules are strict:
- The Burden of Proof: Importers must provide exact Entry Summary numbers (CBP Form 7501) and irrefutable proof of payment. If a customs broker paid on your behalf, you need the banking trails proving you reimbursed the broker for the specific IEEPA duty lines.
- The Timeline Trap: CBP has instituted a rolling 180-day window for CAPE submissions. If you miss the deadline for a specific entry batch, CBP has indicated they will treat the refund claim as abandoned.
- The Audit Risk: Trade compliance lawyers are issuing stark warnings: submitting a CAPE claim puts a target on your back. CBP is using the refund process to audit related entries. If you submit a claim for an IEEPA refund, but CBP discovers you misclassified the product to avoid a different Section 301 tariff, they will offset your refund—or worse, issue penalties.
The Bottom Line for Importers
The IEEPA refund chaos perfectly encapsulates the current state of U.S. trade policy: it is fast, highly volatile, and legally fraught.
As we’ve seen throughout this series—from the Section 338 escalations with Canada to the Full Value Rule and the Section 301 tech war with China—the rules of the game are changing weekly. Importers can no longer rely on static compliance playbooks. Surviving the “Trump 2.0” trade landscape requires real-time monitoring, aggressive legal strategies, and a willingness to completely restructure supply chains at a moment’s notice.
