ECB | Where do the Costs of Higher US Tariffs Fall?

Understanding the impact of tariffs on inflation is a complex task as it involves analysing responses along the pricing chain, including those by foreign exporters, distributors, producers and retailers. At different stages of this pricing chain, domestic firms could respond to tariff announcements by building up inventories before tariffs are implemented, shifting the sourcing of their imports from countries facing higher tariffs to countries facing lower tariffs (trade diversion) and adjusting the pricing of their products to accommodate the impact of tariffs. This analysis is made all the more intricate by exchange rate developments and exemptions for goods in transit at the time of tariff implementation. In this box, we estimate the impact of recently imposed US tariffs on the prices exporters are charging for products delivered to the United States and explore differences in the pricing behaviour of exporters across countries and sectors observed to date. We show that the costs of tariffs are falling mostly on US firms and consumers and only 5% of costs are borne by foreign firms.

Following a series of tariff increases imposed by the United States, both the prices (net of tariffs) and the volumes of goods it imports have been declining. From January to November 2025, the announced statutory effective tariff rate increased significantly from 3% to over 18%.^[1] The annual change in the prices of goods imported into the United States, measured as unit values and reported net of tariffs, has been slightly negative since April. Volumes of imported goods have declined sharply. However, the magnitude of the adjustments in prices and quantities varies across major trading partners, such as China, Canada, Mexico and the EU, which were targeted by higher tariffs. These differences could reflect variations in tariff rates and scope, shifts in the composition of imports and country-specific dynamics.

Exporters to the United States are absorbing only a small fraction of higher tariff-related costs. In aggregate, unit values of imported goods reported net of tariffs show an average pass-through coefficient of 0.95 (Chart A, panel a).^[2] This means that a 10% increase in tariffs implies only a 9.5% increase in prices. Therefore, only a small fraction of the increased tariffs is being absorbed by exporters.^[3] The pass-through coefficient is significantly lower when looking at specific sectors.^[4] However, no significant differences are evident in the estimated tariff pass-through by major trading partners.

The estimated impact of tariffs on import volumes is large. The estimated aggregate elasticity of imports for all product categories stands at -3.7. This means that a 10% increase in tariffs would result in a 37% decline in import volumes. If, by contrast, we focus on only those product categories which are still traded under tariffs, the estimated coefficient declines markedly, albeit remaining economically relevant at ‑0.43. This means that a 10% increase in tariffs would result in a 4.3% decline in import volumes. This difference in estimated elasticity for import volumes suggests that the observed decline is largely associated with products which, in response to tariffs, are no longer traded – meaning they undergo an adjustment through the extensive margin (Chart A, panel b, upper graph). However, volumes also decline markedly for products which are still being traded under tariffs (trade adjustment through the intensive margin; Chart A, panel b, lower graph).

Zooming in on the automotive sector highlights how tariffs triggered significant changes in trade structures, particularly within regional supply chains. In the automotive sector, the results point to a clear decoupling of the United States from China and the EU in favour of Canada and Mexico (Chart B). The surge in car imports from Canada and Mexico reflects a strengthening of existing trade relationships.^[5] This stands in sharp contrast to the results reported for the EU and Japan, which saw both a contraction in the unit value of exported cars and a strong decline in the volume of products subject to tariffs and still exported to the United States.^[6]

While tariffs are reshaping the geography of trade relations with the United States, their costs are falling mostly on domestic importers and consumers. We find that costs associated with higher tariffs are passed down the pricing chain, with consumers currently bearing around a third of the tariff burden (Chart C). And if the higher tariffs are expected to stay in place for a longer period, the available survey evidence from US firms suggests that they will pass a larger share of tariff-related costs on to consumers. Over the longer term, this share could rise to over half as US firms exhaust their ability to absorb costs. Additionally, if the extent to which exporters absorb tariffs remains limited in scope, as reported above, this implies that US firms would absorb around 40% of higher tariff costs in the longer term.
