World Trade Organization Mandate

The World Trade Organization (WTO) provides the common legal and institutional framework governing trade measures adopted by its Members. Its mandate is not to eliminate every trade restriction, but to ensure that restrictions comply with negotiated rules concerning non-discrimination, predictability, transparency and permitted policy exceptions.

Scope of the mandate

Under Article III of the Marrakesh Agreement, the WTO administers covered agreements, provides a forum for negotiations, handles disputes and conducts trade policy reviews. Its rules cover trade in goods, services and trade-related intellectual property through GATT 1994, GATS and TRIPS.

Core disciplines on restrictions

• The most-favoured-nation principle generally requires a trade advantage given to one Member to be extended to all Members.
• The national treatment principle generally prevents imported products from receiving less favourable internal treatment than like domestic products after entry.
• Members may impose customs duties, but must ordinarily remain within their negotiated tariff bindings; GATT Article XI generally prohibits quantitative restrictions such as import quotas.
• Under GATS, market-access and national-treatment obligations depend substantially on each Member's scheduled commitments, while most-favoured-nation treatment is a general obligation subject to permitted exemptions.

Policy space and lawful restrictions

WTO law permits restrictions serving specified public purposes, provided treaty conditions are satisfied. GATT Articles XX and XXI cover general and security exceptions, while specialised agreements regulate sanitary, technical and trade-remedy measures.

• The SPS Agreement disciplines food-safety and animal or plant-health measures, including requirements concerning scientific basis and risk assessment.
• The TBT Agreement seeks to prevent technical regulations and standards from creating unnecessary obstacles to trade while recognising legitimate regulatory objectives.
• Anti-dumping, countervailing and safeguard measures are permitted only under the conditions and procedures of the relevant WTO agreements.

Review and enforcement

Through the Dispute Settlement Understanding, Members may challenge measures alleged to violate covered agreements. If a measure is found inconsistent, the primary remedy is conformity; compensation or authorised suspension of concessions may follow continued non-compliance. The WTO does not independently legislate domestic policy or impose monetary fines.
