Who actually pays a tariff?

A tariff is paid at the border by the importer, but the cost can land on consumers, businesses or foreign exporters. Here is how tariffs work and what research on recent US tariffs found.

Tariffs are back at the center of economic policy debates, and one question comes up again and again: who pays? The short legal answer is simple. The economic answer, which is the one that matters for prices and profits, depends on the product, the market and how long the tariff lasts.

How a tariff is collected

A tariff, also called a duty, is a tax on imported goods. In the United States, it is collected by U.S. Customs and Border Protection (CBP) when goods enter the country. The party legally responsible for paying it is the importer of record, usually the US company bringing the goods in, or a customs broker acting for it. The foreign exporter does not send a payment to the US Treasury.

Duty rates are listed in the Harmonized Tariff Schedule of the United States, which classifies products in detail. Most duties are charged as a percentage of the goods' customs value; some are charged per unit. On top of normal rates, the government can impose additional tariffs under specific laws, for example Section 232 (national security) or Section 301 (unfair trade practices) of US trade law, and those can apply to particular products or countries.

Where the cost ends up

Economists distinguish between who writes the check and who bears the burden, known as the incidence of a tax. The importer pays the duty, but it then has three broad options:

• Pass it on to its customers through higher prices, so that businesses further down the chain and ultimately consumers pay more.
• Absorb it through lower profit margins.
• Push it back onto the foreign supplier by negotiating a lower pre-tariff price, so the exporter effectively pays part of it.

Which happens depends on bargaining power. If buyers can easily switch to a supplier in a country without the tariff, or to a domestic producer, the foreign exporter may have to cut its price. If there are few alternatives, and demand does not fall much when prices rise, more of the cost tends to pass through to buyers.

What research on recent US tariffs found

The tariffs the United States imposed in 2018 and 2019, including those on steel, aluminum, washing machines, solar panels and a wide range of Chinese goods, gave economists a large natural experiment. Several widely cited studies using detailed import data, including work by economists at the Federal Reserve Bank of New York, Princeton and Columbia, and a separate team at UCLA, Yale and other universities, found that the prices US importers paid rose by close to the full amount of the tariffs. In other words, foreign exporters on average did not cut their prices much, and the cost was borne mostly within the United States, by importers, the businesses that buy from them, and consumers.

Later research suggested the picture was more mixed in some sectors and over longer periods, with some costs absorbed by retailers' margins rather than showing up fully in shelf prices, and with supply chains shifting some production to other countries. But the central finding, that US buyers bore most of the direct cost, has held up across studies.

Effects beyond the price tag

Tariffs affect more than the price of the taxed good:

• Domestic competitors can raise their prices too, because the imported alternative is now more expensive. That helps protected producers but costs their customers.
• Manufacturers that use imported inputs, such as steel or components, face higher costs, which can make their own products less competitive.
• Retaliation by trading partners can hit exporters. After 2018, US agricultural exports were a major target of retaliatory tariffs, and the federal government made large payments to farmers to offset losses.
• Trade diversion: importers may switch to suppliers in countries not subject to the tariff, which can reduce imports from the targeted country without reducing total imports much.
• Government revenue rises, which is a real fiscal effect, but that revenue comes from US importers.

How to read tariff news

• Look at what is covered. A headline rate may apply to a narrow list of products, or have exclusions and phase-in dates.
• Consider alternatives. The easier it is to source elsewhere, the more of the cost may fall on the foreign supplier, and the more trade will shift rather than shrink.
• Watch timing. Companies often import ahead of a tariff taking effect, which distorts trade data for a few months before and after.
• Separate the legal payer from the economic burden. "The importer pays" and "consumers pay" can both be true at once.

The bottom line

Tariffs are paid to US Customs by importers. How much of that cost ends up with consumers, US businesses or foreign exporters depends on competition and alternatives, but the best evidence from recent US tariffs is that most of the burden stayed at home.
