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.
