A significant U.S. Supreme Court ruling has invalidated specific tariffs imposed under the International Emergency Economic Powers Act (IEEPA), creating a time-sensitive refund opportunity for many U.S. importers. This brief explains the ruling, who it affects, and the critical deadline you cannot miss.
Overview of the Ruling
The Court's decision invalidates a range of tariffs enacted under IEEPA — an executive authority Congress granted for national emergency responses. The ruling establishes that these specific tariff orders exceeded that authority as applied.
This applies to duties already paid, opening the door for companies to reclaim potentially substantial sums from U.S. Customs and Border Protection (CBP).
Which Tariffs Are Now Invalidated
The following IEEPA-based tariffs are covered by the ruling and may be eligible for refund:
- Global Baseline Tariff — the 10% tariff applied to imports from most countries
- Country-Specific Reciprocal Tariffs — varied rates targeting goods from numerous trading partners, including China, Brazil, India, and the European Union
- Fentanyl-Related Tariffs — specific tariffs applied to goods from Canada, Mexico, and China under the fentanyl emergency designation
Critical Distinction: What Is Not Affected
This ruling does not impact tariffs imposed under other statutory authorities. The following major tariff regimes remain fully in effect:
| Authority | Examples |
|---|---|
| Section 232 | Steel, aluminum, lumber, automotive goods |
| Section 301 | Certain Chinese goods (electronics, industrial components) |
| MFN Rates | Standard WTO-bound duty rates |
If your exposure sits primarily in Section 301 or 232 categories, you are not directly affected by this ruling — though you should monitor ongoing litigation.
Most Affected Industries
The ruling impacts a wide range of businesses involved in global trade. The most directly affected importers are those dealing in high-volume, globally-sourced components:
- C-parts and sub-assemblies — fasteners, connectors, brackets
- Consumer electronics — finished goods and components from non-China origins
- Apparel and footwear — from Southeast Asia, South Asia, and Latin America
- Industrial machinery — imported under the baseline 10% rate
Companies with $5M+ in annual import duties under the invalidated categories should treat this as a material financial event — not an administrative footnote.
The 180-Day Protest Window
There is a critical, non-negotiable deadline to file a protest: 180 days from the date of customs liquidation for each entry. This deadline is absolute and rolls forward daily.
Missing the window for a given entry means permanently forfeiting the refund for that entry. Because CBP processes entries on a rolling basis, older entries are becoming ineligible for protest every single day.
What "liquidation" means
When CBP formally finishes processing an import entry and determines the final duty owed, that entry is "liquidated." The 180-day clock starts from that date — not the import date, not the payment date.
How to Quantify Your Exposure
- Pull your CBP entry summaries — your customs broker or ACE portal can provide these. You need entries from approximately the past 18 months.
- Identify IEEPA-classified duties — look for entries where the tariff authority code corresponds to the affected IEEPA orders.
- Check liquidation dates — any entry liquidated within the last 180 days is potentially eligible. Entries older than 180 days are not.
- Calculate the refund amount — this is the duty paid under the now-invalidated rate, not the total import value.
Filing the Protest
Protests are filed with CBP through the Protest and Summons Filing System (PSFP) or via a licensed customs broker. Each entry requires a separate protest. The forms require:
- Entry number and port of entry
- Date of liquidation
- Legal basis for the protest (the Supreme Court ruling)
- Amount of duties being contested
Tarifix automates this entire workflow: we scan your import history, identify eligible entries, quantify the claim, and generate the protest forms ready for filing.
What to Do Right Now
Given the rolling 180-day window, the urgency is real:
- Identify your customs broker or in-house trade compliance team
- Request a full entry summary for the past 18 months from your ACE account
- Flag entries with duty payments under the affected IEEPA categories
- Prioritize entries by liquidation date — oldest eligible entries first
- File protests before the window closes
