What is a tariff?
A tariff is a tax imposed by a government on goods imported from another country, typically intended to raise the price of imported goods relative to domestically produced alternatives, generate government revenue, or both.

Core tenets
- Tax on imports specifically
- A tariff applies to goods crossing into a country from abroad, distinct from a general sales tax applied to all goods regardless of origin.
- Raises the relative price of imports
- By adding a cost to imported goods specifically, a tariff makes domestically produced alternatives comparatively cheaper, encouraging consumers and businesses to buy domestic goods instead.
- Can be applied broadly or to specific goods
- Tariffs can apply to nearly all imports from a given country or be targeted narrowly at specific products or industries.
How it works in practice
Tariffs are one of the oldest tools of trade policy, historically central to mercantilist economic strategy and still used today for both revenue and protectionist purposes.
- Revenue tariffs
- Applied primarily to generate government revenue, historically a major funding source before widespread income taxation.
- Protective tariffs
- Applied specifically to protect a domestic industry from foreign competition by raising the price of competing imports.
What it is often confused with
Tariffs are a specific trade policy tool, not themselves an economic system; both historically mercantilist and modern market-based economies have used tariffs, for different underlying reasons.
Criticisms and debates
Criticism of tariffs centers on their cost to consumers and the risk of retaliation from other countries.
Consumer-cost critique
Argues that tariffs raise prices for consumers and businesses that rely on imported goods or components, functioning as a tax ultimately paid domestically rather than by the foreign exporter.
Response: Defenders argue that protecting a strategically important domestic industry can justify some consumer cost, particularly where national security or long-term industrial capacity is at stake.
Retaliation critique
Contends that tariffs imposed by one country frequently prompt retaliatory tariffs from trading partners, potentially reducing overall trade and economic output for all parties involved.
Response: Some policymakers argue that the threat of tariffs can itself be a useful negotiating tool to secure more favorable trade terms, regardless of retaliation risk.
