The Penn Wharton Budget Model released an update to its report on effective tariff rates and revenue collection on June 12, 2026. The report presents average rates observed at U.S. customs and the evolution of tariff income. Although it does not involve a regulatory change, these data reflect shifts in the actual application of tariffs (considering exemptions and preferences) and are used by analysts to project trade policy impacts.

Effective tariff rates are a key indicator of the real level of trade protection, as they incorporate exemptions, preferences, and actual collection. The Penn Wharton Budget Model is a respected academic reference in fiscal and trade policy analysis. This report allows operators to compare nominal tariffs with those truly applied at customs and adjust their cost models.
