Rules of Origin in International Trade

Rules of origin are the criteria used by customs authorities to assign a country of origin, or economic nationality, to a product. For goods made across several countries, origin is attributed according to where the product was wholly obtained or underwent the prescribed substantial transformation, rather than merely where it was shipped from.

Tests used to determine origin

The applicable rule is generally product-specific and may use one or more of the following tests:

• A wholly obtained product, such as crops harvested in a country, normally originates in that country.
• A change in tariff classification test asks whether processing changes the product's classification under the Harmonized System at the required level.
• A value-addition rule requires a specified share of domestic or regional value, commonly expressed through regional value content or limits on non-originating inputs.
• A specific-processing rule identifies the manufacturing operation that must occur for origin to be conferred. Minor operations such as simple packing or labelling generally do not confer origin.

Treatment of cross-border production

Inputs may retain foreign origin while the finished good acquires the origin of the country satisfying the relevant transformation rule. Cumulation under some trade agreements permits qualifying inputs from partner countries to be treated as originating, thereby supporting regional production chains.

• The precise threshold or processing requirement depends on the product and the applicable trade agreement or domestic rules.
• Simple routing through, or re-export from, an intermediary country does not by itself alter origin.
• A certificate or declaration of origin and supporting production records enable customs authorities to verify the claim.

Why the determination matters

Preferential rules of origin decide whether goods qualify for reduced tariffs under a free trade agreement. Non-preferential rules may support measures such as anti-dumping duties, quotas, origin marking and trade statistics.

• Rules of origin prevent trade deflection, in which goods from a non-member are minimally processed or merely routed through a preference-receiving country.
• Restrictive or complex rules can raise compliance costs and reduce firms' ability to use tariff preferences.
