National Laws About Tariffs in Different Countries: An Overview

Tariffs are a critical component of international trade policy, used by nations to regulate imports, protect domestic industries, and generate revenue. Each country has its own legal framework governing tariffs, shaped by economic priorities, trade agreements, and geopolitical considerations. This article explores the national laws and recent developments regarding tariffs in key economies, including the United States, the European Union, China, Canada, and India.

### United States

In the U.S., tariffs are primarily governed by federal laws, with the executive branch holding significant authority over trade policy. On April 2, 2025, President Donald Trump declared a national emergency under the International Emergency Economic Powers Act (IEEPA), enabling sweeping tariff measures. The new policy imposes a universal 10% baseline tariff on all imports, excluding Canada and Mexico, effective April 5, 2025. Additionally, reciprocal tariffs targeting countries with large trade deficits with the U.S. will take effect on April 9, 2025.

Key aspects of U.S. tariff laws include:
- The Trade Act of 1974 grants the president authority to impose tariffs for national security or trade remedy purposes.
- The IEEPA allows the president to regulate commerce during national emergencies, as invoked in the 2025 tariff declaration.
- Congressional oversight is limited in practice, as demonstrated by House Republicans blocking legislative efforts to overturn the tariffs.

Economic projections suggest these tariffs could reduce U.S. GDP by 0.7%, shrink capital stock by 0.6%, and eliminate 605,000 jobs. Retaliatory measures from trading partners may further escalate trade tensions.

### European Union

The EU operates under a unified trade policy, with tariffs regulated by the Common External Tariff (CET). The European Commission oversees tariff rates, which vary based on the Harmonized System (HS) classification of goods.

Key features of EU tariff laws:
- The CET ensures consistent tariff rates across all member states, though individual countries can negotiate supplementary trade agreements.
- Recent trade agreements, such as the EU-UK Trade and Cooperation Agreement and participation in the CPTPP, include detailed tariff schedules.
- The EU has engaged in retaliatory tariffs against the U.S., particularly in response to tariffs on EU steel, aluminum, and aircraft.

The EU’s approach balances protectionism with free trade principles, often leveraging tariffs as a negotiating tool in trade disputes.

### China

China’s tariff system is administered by the State Council and the Ministry of Commerce, with rates ranging from 0% to 25%. The U.S.-China trade war has significantly influenced recent tariff policies, with both nations imposing steep tariffs on each other’s goods.

Notable aspects of China’s tariff laws:
- Tariffs are adjusted in response to trade disputes, such as the 125% U.S. tariffs on Chinese imports, met with retaliatory measures from China.
- China uses tariffs to protect strategic industries while promoting exports through lower rates on raw materials.
- The government has unilateral authority to modify tariffs without legislative approval, enabling swift responses to trade conflicts.

The trade war has disrupted global supply chains, raising costs for consumers and businesses in both countries.

### Canada

Canada maintains a relatively open trade policy, shaped by agreements like the United States-Mexico-Canada Agreement (USMCA). While exempt from recent U.S. tariffs, Canada’s trade laws emphasize reciprocity and dispute resolution.

Key elements of Canada’s tariff framework:
- The USMCA outlines specific tariff schedules, reducing barriers for North American trade.
- Canada’s Customs Tariff Act aligns with international standards, though the government can impose surtaxes under the Special Import Measures Act (SIMA) to counter dumping.
- Exemptions from U.S. tariffs are contingent on stable trade relations, which could change if disputes arise.

Canada’s approach prioritizes free trade while retaining safeguards for domestic industries.

### India

India’s tariff policies are overseen by the Ministry of Commerce and Industry, with rates varying by product and trade agreements. India has actively participated in regional trade pacts like the Regional Comprehensive Economic Partnership (RCEP).

Highlights of India’s tariff laws:
- Tariffs range from 0% to 20%, with higher rates protecting agriculture and manufacturing sectors.
- The government can raise tariffs unilaterally, as seen in retaliatory measures against U.S. and EU imports.
- Trade agreements like RCEP include phased tariff reductions to boost regional integration.

India balances protectionism with gradual trade liberalization, adapting tariffs to economic and geopolitical shifts.

### Conclusion

National tariff laws reflect a country’s economic strategy, from the U.S.’s aggressive use of tariffs for trade leverage to the EU’s collective approach under the CET. Recent developments, such as the U.S. national emergency declaration and retaliatory tariffs by China and the EU, underscore the interconnected nature of global trade. As tensions persist, the careful calibration of tariffs will remain vital to minimizing economic disruption and fostering fair trade practices worldwide.
