The most consequential trade law case in decades is before the Supreme Court. V.O.S. Selections Inc. v. United States challenges whether the president has authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA). The outcome could reshape the entire US tariff landscape and potentially trigger refunds of over $130 billion in collected duties.
The Case: V.O.S. Selections Inc. v. United States
V.O.S. Selections, a wine importer, challenged the constitutionality of IEEPA-based tariffs arguing that the president exceeded his authority by using an emergency economic powers law to impose broad trade tariffs. The lower Court of International Trade ruled in favor of V.O.S., finding that IEEPA was never intended to authorize tariffs and that the tariffs effectively constituted a tax — a power reserved for Congress under the Constitution. The case was appealed directly to the Supreme Court given its national significance.
Oral Arguments and Early Signals
Oral arguments were held on November 5, 2025. Several justices expressed skepticism about the breadth of IEEPA tariff authority. Key questions focused on: whether IEEPA's text authorizes tariffs (the word 'tariff' doesn't appear in the statute), whether an ongoing 'emergency' declaration can justify permanent trade policy, and whether Congress intended to delegate tariff-setting power through IEEPA. While predicting outcomes from oral arguments is unreliable, legal observers noted the court appeared to take the constitutional concerns seriously.
Which Tariffs Are Affected
Only tariffs imposed under IEEPA authority would be affected by an adverse ruling. This includes: reciprocal tariffs on 80+ countries (10-46% rates), Canada and Mexico IEEPA tariffs (35% and 25% respectively), and the China fentanyl tariff (10%). Combined, these represent the vast majority of new tariffs imposed since April 2025. If struck down, the effective tariff rate for most countries would drop to just the pre-existing MFN rate (average 3.4%).
Which Tariffs Would Survive
Importantly, several major tariff programs are based on separate legal authority and would be unaffected: Section 232 tariffs on steel (25%), aluminum (25%), copper (50%), and autos (25%) — these are authorized under the Trade Expansion Act. Section 301 tariffs on China (25-100%) — these are authorized under the Trade Act of 1974. MFN (Most Favored Nation) base rates — these are set by Congress through trade legislation. Even if IEEPA tariffs fall, significant duties remain on many products.
The $130 Billion Refund Question
If the Supreme Court invalidates IEEPA tariffs, importers who paid these duties may be entitled to refunds. Estimates suggest over $130 billion in IEEPA-based tariffs have been collected since April 2025. However, refund eligibility depends on several factors: whether the importer filed a timely protest (typically within 180 days of liquidation), whether the ruling is applied retroactively, and whether Congress passes legislation to ratify the tariffs ex post facto. Some legal experts recommend filing protective protests now to preserve refund rights.
What Businesses Should Do Now
Regardless of the outcome, importers should take several steps: (1) File protective protests on recent entries to preserve potential refund rights. (2) Maintain detailed records of all IEEPA tariffs paid. (3) Don't change sourcing strategy based solely on Supreme Court speculation — the ruling could go either way, and even a favorable ruling might be narrowed. (4) Model both scenarios (tariffs upheld vs. struck down) for financial planning. (5) Work with a customs attorney to understand your specific exposure and options.
Timeline and Expected Ruling
The Supreme Court typically issues opinions within several months of oral arguments. Given the November 2025 argument date, a ruling could come at any time — potentially as early as February 2026 or as late as June 2026. The court may issue a broad ruling on IEEPA tariff authority or a narrower decision on procedural grounds. Either way, this case will be the most significant trade law decision in years.
Key Takeaway
The Supreme Court case could dramatically reshape US trade policy. If IEEPA tariffs are struck down, reciprocal tariffs on 80+ countries would be invalidated, though Section 232 and Section 301 tariffs would survive. Importers should file protective protests and prepare for both outcomes.
