Instead, companies accelerated orders ahead of anticipated tariff dates. Imports surged. Then volumes fell. Then they normalized.³ By the end of the year, the macro picture looked stubbornly familiar.
Volatility moved. The deficit did not.
We taxed the calendar. The calendar moved. The structure didn’t.
For Donald Trump , tariffs have always functioned as more than industrial policy. They are leverage, negotiation posture, visible proof of action. The Supreme Court’s ruling constrains one statutory pathway. It does not eliminate the underlying instinct to use trade as an instrument of pressure.
There are other authorities available — Section 232 on national security grounds, Section 301 for unfair trade practices, Section 122 for balance-of-payments measures.⁴ Each is narrower. Each is more procedurally exposed. Each invites litigation. None provide the sweeping flexibility IEEPA appeared to offer.
Congress could, in theory, settle the question cleanly by granting explicit authority. That would require lawmakers to vote directly for a broad-based import tax and to own the economic consequences that follow.
Meanwhile, the warehouse manager is not thinking about statutory alternatives. He is thinking about whether the duties he paid are legally collectible.
Billions were assessed under the IEEPA-based regime. Importers wrote checks at the port. The revenue flowed to Treasury.⁵ If the authority is deemed invalid, companies will seek refunds. That process will not be fast. It will involve protests, filings, maybe years of litigation.
For him, that is not a constitutional debate. It is working capital.
Tariff revenue itself was never a structural pillar of federal finance. Even at elevated levels, it represented a small share of total receipts.⁵ The politics were louder than the fiscal effect.
Industrial policy works only if firms believe the framework will persist long enough to justify capital commitments. Building a plant, reshoring a supply chain, reconfiguring logistics networks — these are multi-year bets.
When executive authority proves legally reversible mid-cycle, firms respond accordingly.
They front-load shipments when rates are rumored to rise.
They delay expansion when litigation clouds authority.
They shorten contract horizons.
They add risk premiums.
That pattern showed itself clearly in 2025. Imports spiked ahead of tariff deadlines. Volumes later dipped. By year’s end, the goods deficit reached a record anyway.²
Volatility is not rebalancing. It is a tax on planning.
The Supreme Court’s ruling narrows one pathway and forces the administration toward more constrained mechanisms. The likely result is not quiet, but improvisation: narrower tariffs justified under security statutes, aggressive messaging, continued litigation.
