What Is the General Agreement on Tariffs and Trade (GATT)?

The General Agreement on Tariffs and Trade (GATT) is the international treaty, signed by 23 countries on 30 October 1947, that set the rules for cutting tariffs and trade barriers after World War II. Its full text is published in the WTO’s official GATT 1947 legal text.

GATT was not simply scrapped in 1995. It lives on inside the World Trade Organization (WTO) as GATT 1994, the agreement that still governs trade in goods. So the real question is not GATT or WTO. The WTO contains an updated GATT.

What Is GATT and Why Was It Created?

GATT was created to rebuild world trade after World War II by cutting tariffs and barriers under common rules. It was signed on 30 October 1947 and applied provisionally from 1 January 1948, per the WTO’s GATT years history. It was meant to sit inside the International Trade Organization (ITO). When the ITO never came into being, GATT became the default framework for global trade.

GATT used the precise term “contracting parties,” not “members,” because it was a treaty applied provisionally, not an organization. Membership grew from the founding 23 to 128 contracting parties by the end of 1994, per the WTO’s GATT membership page. The United States announced in 1950 that it would not seek ratification of the ITO’s Havana Charter, which effectively killed the ITO, per the WTO.

What Are the Core Principles of GATT?

GATT rests on five core principles, each tied to an article of the treaty: most-favoured-nation treatment (Article I), national treatment (Article III), tariff binding (Article II), transparency (Article X), and the ban on quantitative restrictions (Article XI). Together they create a non-discriminatory, predictable rulebook for trade in goods, per the WTO’s GATT 1947 legal text.

What Is Most-Favoured-Nation Treatment Under Article I?

Most-favoured-nation (MFN) treatment means any advantage a country grants to one trading partner’s products must extend immediately and unconditionally to like products of all other contracting parties, under GATT Article I. Despite the name, MFN means equal treatment for everyone, not special favour for one.

The permitted exceptions matter for exporters. Free trade agreements (FTAs) and customs unions under Article XXIV, and Generalized System of Preferences (GSP) schemes for developing countries, may depart from MFN. That is why an FTA rate can sit below the MFN rate.

What Is the National Treatment Principle Under Article III?

National treatment means that once imported goods clear customs, internal taxes and regulations must treat them no less favourably than domestic like products, under GATT Article III. The distinction from MFN is clean. MFN governs treatment at the border between foreign countries. National treatment governs foreign versus domestic goods inside the market.

What Does Binding Tariffs Mean Under GATT Article II?

Binding a tariff means committing to a maximum bound rate that cannot be exceeded without renegotiation and compensation, under GATT Article II. Applied rates can sit below bound rates, and that gap is called tariff water or binding overhang. Each member’s Schedule of Concessions forms an integral part of GATT 1994, per the WTO Analytical Index.

What Are GATT’s Transparency Requirements Under Article X?

Article X requires prompt publication of trade laws, regulations, judicial decisions, and administrative rulings, plus their uniform, impartial, and reasonable administration, under GATT. These rules are the ancestor of modern trade facilitation. For traders, they mean tariff schedules and procedures must be published and findable, which is what makes compliance planning possible across markets.

Why Does GATT Prohibit Quantitative Restrictions Under Article XI?

Article XI generally bans quotas and outright import or export prohibitions, with limited exceptions, under GATT. Tariffs were preferred because they are transparent, measurable, and negotiable, while quotas are opaque and distortionary. The philosophy is simple: tariffs, not quotas.

What Were the GATT Trade Negotiation Rounds?

GATT liberalized trade through eight negotiation rounds between 1947 and 1994, per the WTO’s GATT years history. They ran from the founding Geneva round of 23 countries to the Uruguay Round of 123 countries, which created the WTO. The table below lists all eight.

RoundYearsParticipantsFocus / key outcomeSource
Geneva194723 countriesFounding round; roughly 45,000 tariff concessionsWTO
Annecy194913 countriesFurther tariff cuts; new accessionsWTO
Torquay1950–5138 countriesFurther tariff reductions (about 8,700 concessions)WTO
Geneva195626 countriesModest tariff cutsWTO
Dillon Round1960–6126 countriesTariff cuts amid formation of the European Economic Community (EEC)WTO
Kennedy Round1964–6762 countriesFirst linear, across-the-board cuts; first Anti-Dumping Code (Article VI)WTO
Tokyo Round1973–79102 countriesFirst serious attack on non-tariff barriers; plurilateral codes on subsidies, technical barriers, customs valuation, licensing, and procurementWTO
Uruguay Round1986–94123 countriesCreated the WTO; added GATS and TRIPS; introduced binding dispute settlementWTO

One clarification on anti-dumping: the Kennedy Round’s Anti-Dumping Code, which implemented Article VI, was revised in the Tokyo Round and again in the Uruguay Round, becoming today’s WTO Anti-Dumping Agreement.

What Is the Difference Between GATT and the WTO?

The WTO did not delete GATT. GATT 1994, contained in Annex 1A of the Marrakesh Agreement, incorporates GATT 1947 by reference and still governs trade in goods, while the WTO is the permanent institution around it, per the WTO Analytical Index. In short, GATT is an agreement and the WTO is the organization that houses it.

FeatureGATT (1947–1994)WTO (post-1995)Source
Legal statusProvisional treaty, applied 1948–1995Permanent institution since 1 January 1995WTO
CoverageTrade in goods onlyGoods, services, and intellectual propertyWTO
Dispute settlementWeak; the losing party could block rulingsBinding; rulings adopted by negative consensusWTO
Membership128 contracting parties by 1994166 members as of 30 August 2024WTO

The WTO reached 166 members on 30 August 2024, when Timor-Leste’s accession took effect nine days after Comoros became the 165th member on 21 August 2024, per the WTO’s accession announcement. These were the first new members in nearly eight years.

Why Did GATT Become the WTO?

GATT 1947 was provisional, covered only goods, and had weak enforcement. The Uruguay Round (1986–94) fixed all three. The Marrakesh Agreement, signed 15 April 1994, created the WTO on 1 January 1995, added the General Agreement on Trade in Services (GATS) and the agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and established binding dispute settlement, per the WTO.

Structurally, the WTO Agreement bundles its rules into annexes. GATT 1994 sits in Annex 1A alongside the other multilateral agreements on trade in goods, per the WTO’s Marrakesh Agreement text. GATS and TRIPS occupy their own annexes.

How Does GATT Affect Exporters and Cross-Border Trade Today?

GATT rules give exporters three concrete things. Bound tariff schedules cap customs duties, so a market cannot raise duties above its committed ceiling. MFN rates apply automatically between WTO members, with no registration required. And WTO dispute settlement gives legal recourse through governments when a trading partner breaks the rules.

Transparency does practical work too. Article X publications, such as published tariff schedules and customs procedures, are the raw material exporters use for compliance planning across every market they sell into.

How Commenda Helps With Global Trade Compliance

GATT’s principles of bound rates, non-discrimination, and transparency are the foundation of the duty and indirect tax rules exporters face today. Once goods cross a border, the obligations multiply into value-added tax (VAT), goods and services tax (GST), and sales tax in every market you sell into.

Commenda’s global indirect tax software tracks those cross-border indirect tax obligations so compliance across jurisdictions is certain, with 100+ enterprise resource planning (ERP), application programming interface (API), and custom integrations feeding one source of truth. Verify registrations across markets with Commenda’s global tax ID verification tool, and keep every filing deadline in view with the compliance calendar.
