Country of origin (COO), is the country of manufacture, production, or growth where an article or product comes from.
 There are differing rules of origin under various national laws and international treaties.
 Country of origin labelling is also known as "place-based branding", the "made-in image" or the "nationality bias."
 In some regions or industries, country of origin labelling may adopt unique local terms such as terroir used to describe wine appellations based on the specific region where grapes are grown and wine manufactured.
Rules of origin are used to determine the country of origin of a product for purposes of international trade.
 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, from agreement to agreement.
