There are not many units approved by the state that are qualified to engage in book import and export business, only about 20 * * *. China Book Import & Export Corporation and International Book Trade Import & Export Corporation are relatively large, while others are not very large, such as Xiamen International, Shanghai-Hong Kong Sanlian, Shanghai Foreign Language Bookstore and so on. I don't know how many books you have exported. Generally speaking, the cost of book export consists of tariffs, handling fees, freight and other parts. Companies with different fees charge different percentages. Freight is mainly determined by the weight of books, calculated in kilograms. I don't know where you are. China Map and China Map have many branches in various places. Please check the corresponding company website for details.
