The commercial and industrial center of the country is Skopje, with industries that include glass, beer, bricks, and tobacco. Prilep serves as the nation's agricultural center for tobacco and fruit. Kumanovu is an industrial center for canning and tobacco processing and a trading center for cattle, fruit, and liquor. Domestic commerce typically centers around an urban marketplace, where marketing of farm products is carried out. Formal trade of products and commodities through state enterprises has declined since independence. However, private traders do not always offer a consistent and reliable market outlet for producers.
