1. You don't need a certificate to sell agricultural products in Taobao. Dried fruits without additives can belong to agricultural products and do not need certificates. If you don't want to invest in the early stage, you can avoid the formalities, because not everyone can make money.
2. If you still want to take the formal route, you need to apply for a certificate, one is a business license and the other is a food circulation license. You only need these two certificates, and Taobao is enough. If you want to be more formal, such as having your own packaging, you need a production license. But it is not cost-effective to open a production license for Taobao. With the production license, you can run the company as an enterprise store. You don't need to apply for a production license when there is no profit or the profit is not enough to run a small factory.
