IEEPA Tariffs: What They Are, Key Dates, the Supreme Court Ruling, and What Businesses Should Do Next

Businesses across the country are searching for answers about IEEPA tariffs after the U.S. Supreme Court’s February 20, 2026, decision holding that the International Emergency Economic Powers Act does not authorize the President to impose tariffs. That ruling changed the legal landscape for importers that paid duties under the IEEPA tariff framework and created a major opportunity for many businesses to evaluate potential refund claims.
If your company paid tariffs on imports from Canada, Mexico, China, or under the broader reciprocal tariff measures announced in 2025, this issue may directly affect your bottom line. This guide explains what IEEPA tariffs are, when they were imposed, what the courts ruled, and how the current refund process is developing.
What Are IEEPA Tariffs?
IEEPA tariffs are tariffs imposed under executive orders that relied on the International Emergency Economic Powers Act, commonly called IEEPA, as the claimed legal authority. IEEPA is a federal statute that gives the President certain powers during a declared national emergency involving foreign threats. In the tariff litigation, the government argued that IEEPA’s authority to “regulate” importation included the authority to impose tariffs. The courts rejected that position.
That is why the phrase IEEPA tariffs now matters so much in trade, customs, and refund discussions. The issue is no longer just whether these tariffs existed. It is whether businesses that paid them may now recover those funds.
When Did IEEPA Tariffs Begin?
The main challenge IEEPA tariff measures began on February 1, 2025. According to the Federal Circuit, those executive actions imposed 25% duties on products of Canada, 25% duties on products of Mexico, and 10% duties on products of China.
A second major wave followed on April 2, 2025, when the administration announced broader reciprocal tariffs, including a baseline 10% ad valorem duty on imports from nearly every country. The Federal Circuit also described later China-specific increases during April 2025, including sharp rate escalations before later modifications and pauses.
Key Court Rulings on IEEPA Tariffs
Federal Circuit Decision on August 29, 2025
In V.O.S. Selections, Inc. v. Trump, the U.S. Court of Appeals for the Federal Circuit ruled that IEEPA did not authorize the challenged tariffs. The court emphasized that tariffs are taxes and held that the claimed IEEPA use was too broad to support the executive orders at issue.
Supreme Court Decision on February 20, 2026
The most important ruling came in Learning Resources, Inc. v. Trump on February 20, 2026. The Supreme Court held that “IEEPA does not authorize the President to impose tariffs.” That is now the core legal basis for the current surge in interest in IEEPA tariffs and IEEPA refunds.
For businesses, this ruling matters because it turned the focus from legality to recovery. Once the Court ruled that the statute did not authorize the tariffs, the practical question became how importers could pursue refunds of duties already paid.
Why the IEEPA Tariffs Decision Matters
The Supreme Court’s decision matters for two main reasons.
First, it limits how far a President can go in using emergency-powers statutes to support a broad tariff policy. The Court’s ruling reinforced that tariffs and duties are not something the executive branch can impose under IEEPA without clear congressional authorization.
Second, it created a potentially significant refund opportunity for businesses that paid IEEPA tariffs. CBP has since published refund guidance and rolled out a CAPE-based filing process designed to consolidate claims rather than require importers to work entry by entry.
IEEPA Tariffs and Refund Opportunities
If your business paid IEEPA tariffs, you may be wondering whether a refund is actually available. As of April 2026, CBP has publicly confirmed that importers and authorized brokers can use the CAPE process for IEEPA duty refunds, and CBP materials state that valid refunds will generally be issued within 60 to 90 days following acceptance of a claim.
CBP’s April 8, 2026, Trade Information Notice states that beginning April 20, 2026, importers and customs brokers can file Phase 1 refund requests for IEEPA duties through CAPE. CBP also explains that CAPE is intended to simplify and consolidate the refund process, including interest, rather than handling each refund as a separate entry.
That means the conversation around IEEPA tariffs is no longer just academic or political. It is now directly tied to active refund procedures and potential business recovery.
Which Businesses May Be Affected by IEEPA Tariffs?
Because the challenged tariff measures covered imports from Canada, Mexico, and China, and later expanded into broader reciprocal tariffs affecting imports from nearly every country, the scope was wide. Businesses that import finished goods, components, machinery, parts, or retail products may have been affected.
Commonly exposed sectors can include:
automotive
consumer electronics
apparel and retail goods
industrial equipment and manufacturing inputs
Those categories follow from the broad import scope described in the court opinions and CBP materials.
Important IEEPA Tariffs Dates
To understand the current refund opportunity, it helps to keep the timeline straight:
February 1, 2025: Initial IEEPA tariff measures imposed on Canada, Mexico, and China.
April 2, 2025: Reciprocal tariffs announced, including a 10% baseline duty on imports from nearly every country.
August 29, 2025: Federal Circuit rules in V.O.S. Selections that IEEPA did not authorize the challenged tariffs.
February 20, 2026: Supreme Court rules in Learning Resources that IEEPA does not authorize the President to impose tariffs.
April 20, 2026: CBP begins Phase 1 CAPE filing for IEEPA duty refunds.
What Businesses Should Do Next
If your company paid IEEPA tariffs, the first step is to review whether your entries fall within the affected periods and whether your records support a refund submission. Businesses should look at import data, duty payments, broker records, and entry history as early as possible. This is a practical takeaway based on the structure of the CBP refund process and the documentation requirements implied by CAPE filings.
The sooner a business reviews its position, the sooner it can decide whether to move forward with a formal refund claim. Even though CBP has provided guidance, the details still matter, especially when larger duty amounts are involved.
Final Thoughts on IEEPA Tariffs
The search term IEEPA tariffs now sits at the center of one of the most important trade recovery issues facing importers. The tariffs were imposed in 2025, challenged in court, struck down by the Federal Circuit, and then definitively rejected by the Supreme Court on February 20, 2026. CBP has now opened a CAPE-based refund path, which means affected businesses should take the issue seriously.
If your business paid duties under the IEEPA tariff framework, now is the time to determine whether you may have a valid refund opportunity.
