IGCSE Economics 0455 – Globalisation and Trade Restrictions: Avoiding Dumping

International Trade and Globalisation

Globalisation and Trade Restrictions

Trade restrictions are government measures that limit the free flow of goods and services across borders. While many restrictions aim to protect domestic industries, one specific reason is to prevent dumping.

What is Dumping?

Dumping occurs when a firm exports a product to another country at a price lower than:

  • the price it charges in its home market, or

  • the cost of production (including a reasonable profit).

It is often used by exporters to gain market share quickly, but it can harm the importing country’s producers.

Why Governments Seek to Avoid Dumping

  • Protect Domestic Industries: Prevent loss of market share and potential closures of local firms.

  • Maintain Employment: Safeguard jobs that could be lost if domestic producers cannot compete.

  • Preserve Fair Competition: Ensure that competition is based on efficiency, not on artificially low prices.

  • Prevent Market Distortion: Avoid long‑term price suppression that can lead to monopolistic practices once competitors exit the market.

How Dumping is Measured

The dumping margin shows how much lower the export price is compared to the normal value. It is calculated as:

\$\text{Dumping Margin (\%)} = \frac{\text{Normal \cdot alue} - \text{Export Price}}{\text{Normal \cdot alue}} \times 100\$

Where:

  • Normal \cdot alue = price of the product in the exporter’s domestic market (or a comparable price).

  • Export Price = price at which the product is sold in the importing country.

Anti‑Dumping Measures

When a dumping margin is confirmed, governments may impose the following restrictions:

  1. Anti‑Dumping Duties: Additional tariffs equal to the dumping margin.

  2. Import Quotas: Limits on the quantity that can be imported.

  3. Safeguard Measures: Temporary restrictions to give domestic firms time to adjust.

Example Calculation

Suppose a foreign car is sold for \$20,000 in its home market but exported to Country A for \$15,000.

\$\text{Dumping Margin} = \frac{20{,}000 - 15{,}000}{20{,}000} \times 100 = 25\%\$

An anti‑dumping duty of 25 % would raise the import price to $18,750, narrowing the gap with the domestic price.

Pros and Cons of Anti‑Dumping Policies

AdvantagesDisadvantages
Protects domestic jobs and industries.Can lead to higher prices for consumers.
Promotes fair competition.May provoke retaliation from trading partners.
Encourages foreign firms to price fairly.Administrative costs for investigations and enforcement.

Steps in an Anti‑Dumping Investigation (Simplified)

StepAction
1Domestic industry files a complaint with the investigating authority.
2Preliminary investigation to determine if there is a case to answer.
3Full investigation – collection of data on prices, costs, and market conditions.
4Calculation of dumping margin and assessment of injury to domestic industry.
5Decision – imposition of anti‑dumping duties (often provisional, then final).
6Review – duties are reviewed periodically (usually every five years).

Key Points to Remember

  • Dumping is selling abroad at a price lower than the normal value.

  • Governments use anti‑dumping duties to level the playing field.

  • The dumping margin is expressed as a percentage of the normal value.

  • While protective, anti‑dumping measures can increase consumer prices and risk trade disputes.
