The General Agreement on Tariffs and Trade (GATT) is one of the fundamental pillars of global trade, directly influencing companies that operate in international markets. Although it later evolved into what is now the World Trade Organization (WTO), the GATT remains an essential reference for understanding the rules that govern international trade.
In this article, we explain everything you need to know.
What Are the Four Principles of the GATT?
When companies enter international markets, they must understand the rules and standards that govern trade between countries. The General Agreement on Tariffs and Trade introduced a set of principles designed to strengthen commercial cooperation, reduce tariff barriers, and support fairer trade worldwide. These principles are:
• Non-discrimination This is one of the core pillars of the GATT, divided into two main rules: the Most-Favoured-Nation clause (MFN) and national treatment. The MFN rule ensures that any commercial advantage granted to one country must also be extended to all other GATT members. National treatment states that imported goods must not receive less favorable treatment than domestic products once they enter the country.
• Reciprocity: Under this principle, when one country grants trade concessions, it should receive equivalent concessions in return. This creates more balanced and mutually beneficial international trade relationships.
• Transparency The GATT promotes clear and open communication about trade policies. Countries must disclose their regulations, tariffs, and commercial practices. For businesses, this ensures access to reliable information regarding requirements for importing or exporting goods.
• Fair Competition This principle seeks to prevent practices—such as excessive trade barriers or subsidies—that may distort international markets. The aim is to support healthy competition among companies across different countries.
Which Countries Signed the GATT?
The General Agreement on Tariffs and Trade was signed in 1947 by 23 countries, including the United States, Canada, the United Kingdom, Australia, and several European nations.
The agreement emerged in response to the economic challenges that followed World War II, with the goal of restoring global economic stability through stronger commercial cooperation.
Over the following decades, membership in the GATT expanded significantly. By 1994—when the WTO was formally established—128 countries were part of the agreement.
Although the WTO replaced much of the original GATT structure, the agreement’s core principles continue to guide international trade today.
How Is the GATT Applied Today?
While the General Agreement on Tariffs and Trade was replaced by the WTO in 1995, its principles remain the foundation of many current international trade rules.
The WTO continues to rely on GATT principles to regulate commercial relations among nations.
For businesses, this means that GATT-based rules still govern international trade in goods and services. These rules include:
- Reducing tariff barriers
- Ensuring equal treatment between foreign and domestic products
- Supporting dispute resolution between countries
The WTO—built on the legacy of the GATT—remains a key institution in handling trade disputes and negotiating agreements that promote open and fair global commerce.
In practice, companies operating internationally must stay informed about each country’s commercial regulations and policies. This includes meeting requirements related to market access, equal treatment, and compliance with WTO rules.
