Most enterprises are likely to make higher net profits, averaging 21.73% on sales, due to the fact that they produce higher value-added products and their sales have been increased. Each enterprise generally produces three main products.The domestic market holds the major distribution share although some enterprises distribute their products to both the domestic and foreign markets, for example: USA, Australia, China, Japan, Singapore their and the Middle East. Insufficient demand, caused by low market share, is still obvious problem.
