What the Supreme Court's IEEPA Ruling Means for Importers: A Compliance Roadmap

What did the Supreme Court rule about IEEPA tariffs?

On February 20, 2026, the U.S. Supreme Court ruled 6-3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act does not authorize the President to impose tariffs. The decision invalidated all IEEPA-based tariffs — including the "reciprocal tariffs" and the fentanyl-related tariffs on China, Canada, and Mexico — that had been in effect since early 2025.

How can importers recover duties paid under IEEPA tariffs?

Importers of record who paid IEEPA-based duties between February 2025 and February 24, 2026 are entitled to refunds. CBP is building a new CAPE (Consolidated Administration and Processing of Entries) module within ACE to process claims at scale, with an estimated launch in mid-April 2026. Importers should preserve all entry summaries and duty payment records now.

The U.S. Supreme Court just eliminated the legal foundation for every tariff imposed under IEEPA since February 2025. The Penn Wharton Budget Model estimates $175 billion in potential refunds owed to more than 330,000 importers across 53 million entries. Within hours, the administration pivoted to a 15% global surcharge under Section 122 of the Trade Act of 1974 — a temporary measure capped at 150 days. For compliance teams, the ruling creates a narrow window where refund claims, tariff recalculations, and legal strategy all demand action simultaneously. GingerControl is a trade compliance AI platform that helps importers, exporters, and customs brokers classify products, simulate tariff costs, and track policy changes.

What the Court Actually Said — And Why It Matters

Chief Justice John Roberts, writing for the majority, drew a sharp line between two presidential powers: the power to regulate commerce and the power to tax.

"IEEPA authorizes the President to 'regulate' the 'importation' of goods during a national emergency, but this general regulatory power does not include the distinct and extraordinary power to tax."

— Chief Justice John Roberts, Learning Resources, Inc. v. Trump, 607 U.S. ___ (2026)

The opinion was joined by Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson. Roberts emphasized that IEEPA contains no reference to tariffs or duties, and that Congress has never used the word "regulate" to authorize taxation in any statute. IEEPA was designed for sanctions — blocking enemy assets, freezing transactions with adversaries — not for setting duty rates on commercial imports.

The constitutional foundation is straightforward: Article I, Section 8 vests the power to lay and collect duties exclusively in Congress. Congress delegated specific tariff authorities through statutes like Section 301, Section 232, and Section 122 — each with defined scope and procedural guardrails. IEEPA was never among them.

Aspect	IEEPA (Struck Down)	Section 301	Section 232	Section 122 (Current)
Purpose	Emergency sanctions	Trade retaliation	National security	Balance of payments
Rate cap	None (rates reached 145%)	No statutory cap	No statutory cap	15% maximum
Duration	Indefinite	Indefinite	Indefinite	150 days
Scope	Any country	Country/product-specific	Product-specific	Global, uniform
Court precedent	Struck down (2026)	Survived challenges	Generally upheld	Untested

This table matters for forward planning. The administration's tariff toolkit is now smaller, more constrained, and more vulnerable to litigation than at any point since 2025.

How Large Is the Refund Pool — And Who Qualifies?

The numbers are staggering. CBP collected approximately $166 billion in IEEPA tariffs from more than 330,000 importers of record. The Penn Wharton Budget Model projects that total collections including estimated revenue through early 2026 reached $175 billion — roughly $500 million collected daily under IEEPA authority, equivalent to an average of $1,300 per U.S. household.

Who qualifies for refunds:

• Any importer of record whose entries were subject to IEEPA-based tariffs
• Entries made between February 1, 2025 (when fentanyl tariffs began) and February 24, 2026 (when CBP stopped assessing IEEPA duties)
• Both the "reciprocal tariffs" (Liberation Day, April 2025) and the "trafficking and immigration tariffs" (fentanyl-related, February 2025)
• Applies to all importers — not just those who filed lawsuits

On March 4, 2026, the Court of International Trade ordered CBP to process refunds for all importers of record. Judge Richard K. Eaton, designated as the sole CIT judge for IEEPA refund cases, stated that "all importers of record whose entries were subject to IEEPA duties are entitled to the benefit of the Supreme Court's decision."

However, the CIT suspended that order on March 6 while CBP develops the technical infrastructure to process refunds at scale. The government has also signaled it will challenge the CIT's order.

Treasury Secretary Scott Bessent called the potential refunds "ultimate corporate welfare" and suggested the process "could be dragged out for weeks, months, years." This signals the administration's intent to delay, not cooperate, on refund processing.

How Does CBP's CAPE Refund System Work?

CBP is building a new system called CAPE (Consolidated Administration and Processing of Entries) — a dedicated module within ACE designed specifically for IEEPA refund claims. As of March 19, 2026, development progress stands at:

CAPE Component	Completion	Function
Claim Portal	~73%	Importers/brokers submit entry lists via CSV upload
Mass Processing	In development	Automated removal of IEEPA HTS provisions, duty recomputation
Review & Liquidation	~80%	Reliquidation of finalized entries, discrepancy resolution
Refund Processing	~63%	Electronic ACH refund to importer's bank account on file

The four-step refund process:

1. Claim Submission — Importers or their customs brokers submit refund requests through the CAPE portal in ACE, providing entry-level data via CSV uploads
2. Automated Processing — CAPE removes IEEPA-related Chapter 99 HTS provisions and recomputes duties owed
3. Review Period — System resolves discrepancies and confirms no other debts are owed to the government
4. Refund Disbursement — Overpaid amounts are refunded via ACH electronic payment

CBP estimates CAPE will launch around mid-April 2026, processing simpler refund scenarios first before scaling to more complex cases.

What importers should do now to prepare for CAPE:

• Register for ACH refunds with U.S. Customs if you haven't already — refunds will be electronic
• Compile all entry summaries for IEEPA-affected imports (February 2025 through February 2026)
• Verify entry data accuracy — CAPE's automated checks will flag discrepancies, and errors could delay your refund
• Protest any liquidated entries within the 180-day post-liquidation window to preserve refund rights
• Coordinate with your customs broker — brokers can submit claims on your behalf through the portal

GingerControl's Tariff Calculator covers the full U.S. tariff stack: base duty, Section 232, Section 301, Chapter 99, and Section 122 reciprocal tariffs across 200+ countries. If you need to recalculate your duty exposure without IEEPA layers, the Calculator can model pre-refund and post-refund scenarios side by side.

What Replaced IEEPA Tariffs? Understanding Section 122

Within hours of the Supreme Court decision, President Trump issued a proclamation imposing a 10% global tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026. The rate was raised to 15% on February 22 — the statutory maximum.

Section 122 is fundamentally different from IEEPA in three critical ways:

Rate cap. Section 122 tariffs cannot exceed 15%. IEEPA tariffs had no cap — rates on Chinese imports reached 145%.

Time limit. Section 122 tariffs expire after 150 days — July 24, 2026 — unless Congress votes to extend them. IEEPA tariffs were indefinite.

Scope. Section 122 tariffs must apply globally and uniformly. They cannot be country-specific the way IEEPA tariffs were.

Key exemptions from the Section 122 surcharge:

• Products already subject to Section 232 tariffs (steel, aluminum, copper, autos, semiconductors)
• Certain agricultural products, pharmaceuticals, energy products, and critical minerals
• Civil aircraft and parts covered under the 1979 Agreement on Trade in Civil Aircraft
• Canadian and Mexican goods qualifying under USMCA

For most importers, the shift from IEEPA to Section 122 represents a significant duty reduction. A Chinese-origin product that was subject to a 145% IEEPA tariff plus base duty is now subject to 15% Section 122 plus base duty (and still subject to any applicable Section 301 tariffs). But the 150-day clock creates its own compliance challenge: whatever replaces Section 122 after July 24 will reshape your cost structure again.

What Should Your Compliance Team Do in the Next 90 Days?

This is a high-stakes transition period. The refund process is building, the replacement tariff is temporary, and the administration is launching new trade investigations that could produce longer-term tariff structures. Here is the action plan:

Week 1 — Secure Your Refund Position

1. Quantify total IEEPA duties paid across all entries (February 2025 through February 2026)
2. Gather documentation: entry summaries, duty payment records, commercial invoices, proof of payment
3. Verify your ACH registration with CBP for electronic refund disbursement
4. File protests on any liquidated entries still within the 180-day window
5. Decide your refund strategy: CAPE portal (when available), formal protest, or CIT litigation

Weeks 2–4 — Recalibrate Your Tariff Models

1. Remove IEEPA assumptions from all landed cost calculations
2. Model the Section 122 surcharge (15% global, with exemptions) across your product lines
3. Stress-test scenarios for post-July 24 tariff structures (expanded Section 301, new Section 232 investigations, Congressional action)
4. Brief procurement and finance on the tariff uncertainty window and the range of possible duty costs

Weeks 5–12 — Prepare for the Next Tariff Regime

1. Monitor USTR for new Section 301 investigation announcements
2. Review whether any products fall within pending Section 232 investigations (pharmaceuticals, aircraft, robotics, drones, PPE)
3. Audit HTS classifications — with tariffs shifting across multiple legal authorities, an incorrect code could mean paying the wrong rate or triggering penalties
4. Prepare for another round of tariff implementation once the administration announces its post-Section 122 framework

GingerControl's HTS Classifier follows GRI logic and asks clarifying questions before assigning a classification — producing audit-ready reports grounded in Section Notes, Chapter Notes, and relevant cross rulings. GingerControl is a pre-classification research tool. It follows the same reasoning process a licensed customs broker uses — GRI analysis, Section/Chapter Note review, and cross ruling research — but the final classification decision benefits from professional judgment. GingerControl produces audit-ready documentation that supports the classification decision; it does not provide legal advice or replace licensed customs expertise.

What Does This Mean for the Future of Presidential Tariff Authority?

The Learning Resources decision is the most significant constraint on executive tariff power in decades. Its implications extend well beyond IEEPA:

IEEPA tariffs are permanently off the table. Any future president who attempts to use IEEPA for tariffs will face immediate legal challenge with binding Supreme Court precedent against them.

Remaining tariff authorities are narrower. Section 301 requires specific unfair trade practice findings. Section 232 requires a national security nexus. Section 122 is capped at 15% and 150 days. None offer the speed, scope, or rate flexibility that IEEPA provided.

Litigation risk is now embedded in every tariff action. The Supreme Court demonstrated willingness to strike down executive tariff actions. Importers, trade associations, and foreign governments will challenge future tariffs more aggressively, knowing courts are receptive.

Tariff planning becomes scenario-based, not rate-based. Compliance teams can no longer model tariffs as stable inputs. The legal authority behind any given tariff determines its durability, scope, and vulnerability to reversal. Smart compliance means modeling multiple scenarios simultaneously.

As Baker McKenzie noted, the ruling "triggers major shifts in U.S. trade enforcement strategy" — pushing the administration toward tools that are slower to deploy but harder to challenge.

Frequently Asked Questions

What did the Supreme Court decide in Learning Resources v. Trump?

The Court ruled 6-3 that IEEPA is an emergency sanctions law, not a tariff statute. Chief Justice Roberts held that the power to "regulate" imports does not include the power to tax them. This invalidated all IEEPA-based tariffs imposed since February 2025, including both the reciprocal tariffs and the fentanyl-related tariffs on China, Canada, and Mexico.

Am I eligible for an IEEPA tariff refund?

If you were the importer of record on any entries subject to IEEPA duties between February 2025 and February 24, 2026, you are likely eligible. The Court of International Trade ruled that all importers of record are entitled to refunds — not just those who filed lawsuits. Preserve your entry summaries and duty payment records immediately.

When will CBP start processing IEEPA refunds?

CBP is building the CAPE refund system within ACE, targeting a mid-April 2026 launch. As of March 19, the system is approximately 63-80% complete across its four components. Simpler refund scenarios will be processed first, with more complex cases phased in over time.

What is Section 122 and how does it differ from IEEPA tariffs?

Section 122 of the Trade Act of 1974 authorizes a temporary, global tariff capped at 15% for up to 150 days. Unlike IEEPA tariffs, Section 122 cannot be country-specific, has no rate flexibility above 15%, and expires automatically on July 24, 2026 unless Congress extends it. Products subject to Section 232 duties are exempt.

Are Section 301 tariffs on China still in effect?

Yes. The Supreme Court's decision only invalidated tariffs imposed under IEEPA. Section 301 tariffs on Chinese-origin goods — ranging from 7.5% to 100% depending on the product — remain fully in effect and continue to stack on top of base duty rates and any applicable Section 232 duties.

How can GingerControl help with post-IEEPA compliance?

GingerControl's Tariff Calculator models the full U.S. tariff stack — base duty, Section 232, Section 301, Chapter 99, and Section 122 — across 200+ countries with date-sensitive calculations. The HTS Classifier produces audit-ready classification reports following GRI logic, helping importers verify their codes are accurate and defensible during this period of shifting tariff authorities.

Should I file a CIT lawsuit or wait for the CAPE portal?

Both paths have trade-offs. The CAPE portal is expected to be simpler and require minimal importer submissions, but it's not yet live and the government may challenge the scope of administrative refunds. Filing a CIT claim preserves your legal rights and prevents statutory liquidation from barring recovery. Many law firms recommend filing protective CIT claims now while also preparing for CAPE submission.

What happens after Section 122 expires on July 24, 2026?

The administration has signaled that Section 122 is a stopgap. Expect new Section 301 and Section 232 investigations to produce longer-term tariff structures before the July 24 expiration. USTR has already announced new Section 301 investigations into unfair trade practices. Whatever replaces Section 122 will likely be more targeted — product-specific or country-specific — rather than a universal surcharge.
