There are two common types of rules of origin depending upon application, the preferential and non-preferential rules of origin (19 CFR 102). The exact rules vary from country to country. Non-preferential rules of origin are used to determine the country of origin for certain purposes. These purposes may be for quotas, anti-dumping, anti-circumvention, statistics or origin labeling. The basis for the non-preferential rules originates from the Kyoto convention which states that if a product is wholly obtained or produced completely within one country the product shall be deemed having origin in that country. For a product which has been produced in more than one country the product shall be determined to have origin in the country where the last substantial transformation took place.
