Country of origin (CO) represents the country or countries of manufacture, production, design, or brand origin where an article or product comes from. For multinational brands, CO may include multiple countries within the value-creation process. There are differing rules of origin under various national laws and international treaties. Country of origin labelling (COL) 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. Place-based branding has a very ancient history. Archaeological evidence points to packaging specifying the place of manufacture dating back to some 4,000 years ago. Over time, informal labels evolved into formal, often regulated labels providing consumers with information about product quality, manufacturer name and place of origin. Country of origin of a product can have several possible definitions. It can refer to: (a) "the place from which the merchandise was directly received; that is the last border crossed or port entered before reaching its final destination; (b) the country of consignment (i.e. from where the goods were sold); or, (c) the country of original growth or extraction." The inclusion of place of origin on manufactured goods has an ancient history. In antiquity, informal branding which included details such as the name of manufacturer and place of origin were used by consumers as important clues as to product quality. David Wengrow has found archaeological evidence of brands, which often included origin of manufacture, dating to around 4,000 years ago. Producers began by attaching simple stone seals to products which, over time, were transformed into clay seals bearing impressed images, often associated with the producer's personal identity thus providing information about the product and its quality.
