That is depends on the products you want to manufacture. There are many good manufacturers in China, but Chinese manufacturers are very professional only for their expertise, your custom manufacturing product needs more than one process to make. Therefore, it is better to use a sourcing company to consolidate with different manufacturers. In addition, it requires a lot of experiences in terms of languages and import and export process to communicate with Chinese manufacturers. Shipping and Export are not their expertise therefore you cannot get a good experience. What’s more, you cannot trust them to control the quality of their own products; we have product quality control process throughout the whole manufacture process, we have our own shipping company, JWB sourcing team is your best partner and will assure you a pleasant experiences.
