Who bears the burden of tariffs on US imports?
Core argument: The authors estimate tariff pass-through into U.S. import prices at 94% in 2025, up from 80% in 2018–2019, with few imports showing low pass-through, while exchange rate pass-through is low in both periods.
After peaking at 32.8% in April, the statutory rate in September was 27.4%. To calculate the “actual” rate, we divide the tariff revenues that the U.S. government collects each month on imports from each exporter-HTS pair by the value of those imports. [HTS stands for Harmonized Tariff Schedule, a standardized system of codes used to classify products for customs purposes]. The ex-tariff price of U.S. imports from China declined by 2.5% and the price of imports from the others were essentially unchanged or rose by two percent or less. Our preferred methodology results in an estimated tariff pass-through rate of 80% during 2018-2019 and 94% during 2025. There are few indications of any meaningful set of imports exhibiting low pass-through. By contrast, exchange rate pass-through into U.S. import prices is low across both periods. The tariffs have led to striking changes in sourcing patterns. The share of Chinese exports in U.S. goods imports collapsed from 22% at the end of 2017 to about 12% at the end of 2024. By September 2025, China’s share was only 8%. Given the high pass-through to import prices and the importance of imported inputs in U.S. manufacturing, much of the incidence of the tariffs falls on U.S. producers [roughly equivalent to a tax on manufacturing of 1 to 2 ppt].
