Rules of Origin
Rules of Origin are the criteria used to determine the “economic nationality” — the country of origin — of a product for the purposes of trade policy. Because goods are often made from materials and processing in several countries, these rules decide which country a product officially originates from, which in turn determines the tariff rate, eligibility for trade-agreement preferences, quotas, anti-dumping duties and origin marking.
They come in two forms: non-preferential rules (for general trade measures and origin marking) and preferential rules (which decide whether goods qualify for reduced or zero duty under a free-trade agreement). Origin is typically established by tests such as wholly obtained, substantial transformation, a change in tariff classification, or a regional value content threshold. Proving origin (via a certificate of origin or self-declaration) is what unlocks preferential tariffs — so rules of origin are central to whether an FTA actually saves duty, and a frequent area of customs complexity and audit.
An FTA only cuts your duty if the goods actually qualify as originating — and rules of origin are the fine print that decides. In a world of multi-country manufacturing, meeting (and proving) origin is often the difference between paying full tariff and zero. It is where trade-agreement savings are won or lost, and a hotspot for customs audits.
Why do rules of origin matter?
They determine a product's country of origin, which sets its tariff rate and whether it qualifies for reduced duty under a free-trade agreement.
How is origin determined?
By tests such as wholly obtained, substantial transformation, change in tariff classification, or regional value content.
