WTO Rules of Origin

Rules of origin determine a product's economic nationality, which may differ from the country from which it was shipped. Under the WTO framework, origin is identified mainly through the wholly obtained test or, where several countries participate in production, through substantial transformation criteria.

Core tests for determining origin

The applicable customs authority examines where the product was produced and how imported inputs were transformed.

• Goods produced entirely in one country, such as minerals extracted or crops harvested there, are treated as wholly obtained in that country.
• When two or more countries participate in production, origin is generally assigned to the country where the last substantial transformation occurred.
• Substantial transformation may be expressed through a change in tariff classification, a specified value-added requirement, or a prescribed manufacturing or processing operation.

WTO framework

The Agreement on Rules of Origin, contained in Annex 1A of the WTO Agreement, covers non-preferential origin rules. It seeks harmonised, objective and predictable criteria, but WTO members continue to apply national non-preferential rules subject to WTO disciplines.

• Non-preferential rules are used for measures such as most-favoured-nation treatment, trade remedies, safeguards, origin marking and trade statistics.
• Rules must be transparent, administered consistently and based primarily on a positive standard stating what production confers origin.
• Origin determination must not be used as an instrument to pursue trade objectives or create restrictive or disruptive effects on international trade.

Preferential origin

Preferential rules determine whether goods qualify for reduced tariffs under arrangements such as free trade agreements or preference schemes. They are distinct from non-preferential rules and are addressed through Annex II of the WTO Agreement, which emphasises clear publication, positive criteria and review of administrative decisions.
