Calculation Formulas

USTR Formula (Δτi):

Δτi = (xi - mi) / (ε × φ × mi)

-Δτ is USTR's calculation of the tariff on country i that will lead to balanced bilateral trade. xi is US exports to country i, and mi is US imports from country i. ε is the elasticity governing the change in trade flows in response to changes in tariff and φ is the pass-through rate of tariff to domestic prices.

US Reciprocal Tariff:

ceiling(max(-Δτi/2 × 100, 10))

USTR's calculation of the tariff (-Δτ), divided by 2, but no less than 10%, rounded up to the nearest integer. This is the reciprocal tariff published on Liberation Day.
