Rules of origin
Determining where a product comes from is no longer easy when raw materials and parts criss-cross the globe to be used as inputs in scattered manufacturing plants. Rules of origin are therefore needed to attribute one country of origin to each product. They are the criteria used to define where a product was made and are important for implementing other trade policy measures, including trade preferences (preferential rules of origin), quotas, anti-dumping measures and countervailing duties (non-preferential rules of origin).
