Model DiplomatApril 25, 20263 min readUnited States [UsatodayTariff refunds are being issued. Will you get one?](https://www.usatoday.com/story/business/finance/2026/04/20/tariff-refund-portal-opens-online-trump-duties-customs-border-protection/89697226007/)[TheglobeandmailThousands of companies file claims as U.S. tariff refund system launches - The Globe and Mail](https://www.theglobeandmail.com/business/international-business/article-companies-file-claims-us-tariff-refund-system-donald-trump/) ## Supreme Court Kills Trump's IEEPA Tariffs — $166B Refund Race Is On *A February Supreme Court ruling struck down Trump's IEEPA tariffs, triggering the largest importer refund operation in U.S. history. Here's who gets paid.* The U.S. government launched its **CAPE (Consolidated Administration and Processing of Entries) portal on April 20**, opening the floodgates for more than **330,000 importers** to claim refunds on tariffs the Supreme Court ruled unconstitutional in February 2026. Total exposure: **\~$166 billion** across roughly **53 million shipments**. The first wave is already moving — as of April 9, **56,500 importers** had completed claims covering **\~$127 billion**, or about 77% of eligible refunds. [Source: The Globe and Mail](https://www.theglobeandmail.com/business/international-business/article-companies-file-claims-us-tariff-refund-system-donald-trump/ "theglobeandmail.com") ## The Legal Trigger The Supreme Court's February ruling found that the tariffs Trump imposed under the **International Emergency Economic Powers Act (IEEPA)** exceeded presidential authority — a direct constraint on the executive's ability to use national emergency statutes as a trade weapon. The Court of International Trade then ordered CBP to return duties collected under that authority. This is not a discretionary exclusion program like previous USTR processes; it is a **court-mandated refund** with interest attached to eligible claims. That distinction matters. The administration had no choice here — CBP built the CAPE system under judicial order, not policy preference. ## Who Qualifies — and Who Doesn't Eligibility is narrow and procedural: - **In:** Any importer who paid IEEPA-specific tariffs and has a CBP-approved claim filed within the applicable **80-day window**. - **Out:** Tariffs imposed under separate authority — Section 301 (China), Section 232 (steel/aluminum) — are **not covered**. Trump's subsequent global tariff, imposed under a different legal mechanism after the IEEPA ruling, is also excluded and faces its own litigation. - **Out:** Individual consumers. No direct-to-household refund program exists. The proposed **$1,700-per-family tariff dividend** floated in 2025 was never enacted.

The system consolidates refunds into a single electronic payment rather than processing them shipment-by-shipment — a critical design choice given the volume. Customs brokers are handling submissions for many smaller firms; broker fees are running roughly **$250 per filing**, which poses a real cost-benefit threshold for importers with modest tariff exposure. Toy manufacturers — **Basic Fun** and **Learning Resources** among them — reportedly set up internal "war rooms" to manage the submission sprint.

For a broader view of how this intersects with ongoing U.S. trade realignment, see [US Politics](https://modeldiplomat.com/discover/us-politics "modeldiplomat.com") and [International Trade](https://modeldiplomat.com/discover/international "modeldiplomat.com"). ### What to Watch Next The **$2.9 billion** in complex, manually processed cases flagged by CBP as potentially excluded from Phase 1 is the immediate pressure point — those rulings come through the Court of International Trade on a rolling basis. More consequentially, watch whether challenges to Trump's **replacement global tariff** reach the Supreme Court by summer; if that authority is also struck down, a second, potentially larger refund cycle opens. The administration's legal theory on trade emergency powers is 0-for-1 at the Court — the next case will define how much unilateral tariff leverage any president retains.
