The Trump administration has rolled out a fresh set of tariffs to replace duties the Supreme Court dismantled, but the substitute revenue stream comes up roughly $825 billion short over the next decade.
The new tariff framework, which took effect recently on dozens of trading partners and includes separate measures targeting Brazil and Canada, would generate about $950 billion through 2036. That compares to $1.7 trillion projected from the broader emergency tariffs the court invalidated, according to estimates from the Committee for a Responsible Federal Budget.
The administration's replacement duties are narrower and carry more carveouts than their predecessors. On an annual basis, the new levies would raise roughly $105 billion, offsetting about 60% of what was lost when the Supreme Court struck down the emergency tariff regime.
The architectural difference explains the revenue gap. The administration's original tariffs were imposed under emergency powers, casting a wide net with minimal exclusions. The new duties rest on Section 301 of the Trade Act of 1974, a framework that requires formal investigation and public comment before implementation. This process allows trade officials to exclude specific products deemed likely to cause excessive economic disruption.
Notably, energy products are among the excluded categories, a choice that limits the risk of amplifying inflation linked to oil sanctions. The narrower scope reduces both the economic shock and the revenue haul compared to what a broader regime could generate.
Treasury data underscores the challenge of transitioning between tariff systems. In June, as the old duties were being unwound, net customs receipts dropped to negative $25.6 billion as refund payments to importers exceeded new tariff collections.
The White House has pushed back on the characterization that the new tariffs are simply a replacement scheme. A senior official said the timing was meant to ensure business continuity and predictability as temporary tariffs expired, not necessarily to recreate the previous system in full.
The projections assume the new tariffs survive legal challenges and remain in place. They do not account for potential additional trade actions the administration may announce.
Author James Rodriguez: "The math reveals a genuine constraint: legal tariffs that survive court scrutiny carry a revenue cost, and the administration is choosing economic caution over maximum extraction."
