Historically, countries have used tariffs to protect domestic products from foreign competition. While many countries have reduced tariffs through trade agreements, that trend is being undone fast, given the broad tariff regime announced by U.S. President Trump in 2025.
The Trump tariffs are the most sweeping in the U.S. since before World War I, ending what had been a long liberalization of trade barriers through decades of international agreements and the build-up of institutions meant to increase trade worldwide. The tariffs, including a baseline 10% on nearly all U.S. imports and additional tariffs the administration is dubbing “reciprocal” for many specific countries, are far higher for nations that have long been competitors of the U.S., and many that until 2025 weren’t. Vietnam (56%), Cambodia (59%), and Sri Lanka (54%) were among the hardest hit, but, so, too, were some of the world’s most valuable trade partnerships: tariffs were increased significantly on goods from China (44%), the EU (30%), and Japan (34%).
Key Takeaways
- Tariffs are taxes on imports imposed by a government to help direct domestic consumers toward goods made within the country.
- Less industrialized countries, such as those in Africa and the Caribbean, traditionally have had the highest tariff rates.
- In April 2025, the U.S. introduced significant new tariffs that put tariff rates well above historic rates. They are, for now, the world’s highest.
- Many economists view tariffs as liable to increase consumer prices and lead to higher inflation.
- Tariffs are not the only trade barrier: others include exchange controls, subsidies, fair trade laws, local-content requirements, and quotas on imports and exports.
While slapped on goods from specific countries, tariffs are taxes paid by consumers within the country that applies them. Those who support them argue they redirect domestic consumer demand toward goods made within the country. The 2025 Trump administration tariffs far outstrip previous highs worldwide for a country’s average tariff rate, according to data from the World Trade Organization. In 2024, those at the high end of the list included Algeria (18.9%), Cameroon (18.1%), and Tunisia (19.5%). Below, we review these figures further and explore their economic implications.
World’s Highest Tariffs
The landscape of global tariffs shifted dramatically following the U.S. administration’s April 2025 tariff rollout. Those tariffs include a baseline 10% on virtually all imports, with additional tariffs (the Trump administration labels them “reciprocal”) depending on the country. Below are the combined figures, which stand as the world’s highest as of April 2025.
These rates represent a consequential shift from historical patterns. While traditionally less-developed African and Caribbean countries maintained the highest tariffs, the U.S.’s moves are likely the beginning of a worldwide ratcheting up of tariffs on U.S. goods in response. The administration imposed particularly high tariffs on goods from many Southeast Asian manufacturing hubs. Major longstanding trading partners had substantial increases in duties placed on their goods, including China (44%), the European Union (30%), and Japan (34%).
Economists and international organizations have expressed concern about these dramatic increases, with the World Trade Organization warning they could cause global trade volumes to contract by 1% in 2025. “No one wins a trade war,” Justin Wolfers, professor of public policy and economics at the University of Michigan, told Investopedia, noting that economists are “very” concerned about a recession coming out of the significant increases in duties.
Warning
In the map below, we use a weighted average of tariffs calculated by the World Trade Organization for each country. However, countries often impose tariffs on specific goods that can be far higher than the average. For example, India has a 70% tariff on imported passenger vehicles, and many nations, including the U.S., had, before 2025, carved out specific areas of their economies to protect via import duties.
Lowest Tariffs
In contrast to the countries with high tariff rates, some nations have maintained very low or even zero tariffs. Despite the threats in recent years of protectionism led by the U.S., these countries had continued, at least until 2024, to maintain open trade policies. On the map below, those with the lowest or no tariffs in 2024 are in blue. They include Hong Kong, Singapore, Georgia, and Australia.
Tariffs vs. Free Trade
When Adam Smith published “The Wealth of Nations” in 1776, international trade was primarily defined by extremely restrictive import tariffs and quotas. Following Smith, David Ricardo in early 19th-century works developed the case for free trade in the early 19th century through his theory of comparative advantage.
Ricardo argued that countries benefit from specializing in producing goods where they have a relative efficiency advantage and trading for other goods, even if one country is more efficient at producing everything. Suppose you’re the manager of a baseball team. You could have Shohei Ohtani pitch and hit—he’s an elite talent at both—but you might produce more wins by having him focus on being a position player to maximize his effectiveness and prevent injury. You certainly, too, wouldn’t have Ohtani handing out water to other players when not up at bat or mowing the grass. That’s why economists argue that nations should specialize in areas where they have comparative advantages and freely trade with others for the rest (get someone else to handle the other role on the team). This way, total economic output increases, with each participating country benefiting over time. For this reason, economists have long argued for bringing down trade barriers—you want to make it easier for your country to get the goods that aren’t to its advantage to make.
Note
The average tariff rate for the U.S. in 2024 was 0.9% and was estimated to increase to between 22.5% and 24% from the April 2025 changes made by the Trump administration.
Ricardo’s ideas formed the foundation of modern trade theory and contributed to the consensus among economists that lowering trade barriers encourages economic growth—a view particularly strong among European and American economists in the second half of the 20th century, leading to a general decline in tariffs worldwide.
What Happens When There Are High Tariffs on Imported Goods?
High tariffs on imported goods increase the prices of these goods. As a result, consumers end up paying higher prices for the goods. Alternatively, consumers can opt to purchase substitute goods that are domestically made, which are most likely to be cheaper.
Do Any Countries Have No Tariffs?
Yes, a few countries do not have any tariffs, and several have very low tariffs. The World Bank reports tariffs on a weighted mean. Hong Kong (China), Macau (China), and Sudan have no tariffs.
Which Country Has the Highest Import Duty?
As of April 2025, that would be the U.S., with tariffs well above historic highs in recent decades.
The Bottom Line
Until 2025, many countries had abolished tariffs or lowered them significantly after signing free trade agreements to pursue foreign markets for their goods. Changes begun by the U.S. are likely to spark rounds of negotiations and reciprocal tariffs implemented by trading partners to match the Trump administration’s moves.
