What is a Tariff? Definition, Types, Purpose, and Economic Effects

What is a Tariff?
A tariff is a tax or duty imposed by a government on imported goods and services. It is one of the oldest trade policy tools, used to:
Control international trade by making foreign goods more expensive.
Protect domestic industries from foreign competition.
Generate revenue for the government.
By increasing the cost of imports, tariffs encourage consumers to buy locally produced goods, supporting domestic businesses and employment.


Types of Tariffs
Ad Valorem Tariff – A fixed percentage charged on the value of imported goods (e.g., 10% on electronics).
Specific Tariff – A fixed fee based on quantity (e.g., ₹500 per ton of steel).
Compound Tariff – A combination of both ad valorem and specific tariffs.
The World Trade Organization (WTO) regulates tariffs globally, ensuring fair trade practices among member nations.


Purpose and Functions of Tariffs
Tariffs serve multiple economic and political purposes:
1. Protection of Domestic Industries
High tariffs on imports (e.g., steel, textiles) make foreign goods costlier, boosting local production.
Helps safeguard jobs and promotes industrial growth.
2. Revenue Generation
In developing nations, tariffs contribute significantly to government income.
According to the IMF, some countries rely on tariffs for up to 25% of their revenue.
3. Strategic Trade Tool
Used in trade negotiations to pressure other nations.
Retaliatory tariffs may be imposed to counter unfair trade practices.


Economic Impact of Tariffs
While tariffs benefit domestic producers, they also have downsides:
Pros:
✔ Supports local businesses and employment.
✔ Reduces dependency on foreign goods.
Cons:
✖ Increases prices for consumers.
✖ May lead to trade wars, as seen in the US-China trade conflict (2018-2024).
✖ Can disrupt global supply chains, raising production costs.
Historical Example: The Smoot-Hawley Tariff Act (1930) in the US worsened the Great Depression by triggering global trade wars.


Global Tariff Framework & WTO Regulations
The WTO ensures fair tariff policies through:
Most Favored Nation (MFN) Principle – Equal tariffs for all WTO members.
Anti-Dumping Duties – Temporary tariffs to prevent unfair pricing.
Trade Negotiations – Countries agree on tariff reductions over time.


Modern Trends in Tariff Policies
Declining Global Tariffs – Average global tariff is 2.59% (WTO, 2024).
Rise in Protectionism – Trade wars (e.g., US-China) disrupt global trade.
Climate-Related Tariffs – The EU’s Carbon Border Tax (CBAM) penalizes high-carbon imports.
