Exporting branded products is more troublesome. First, apply for the license at the Industrial and Commercial Bureau, then apply for the qualification certificate of self-operated import and export right at the local foreign economic and trade commission (I can't remember the full name), and apply for the record at the inspection and quarantine bureau affiliated to this region. After that, find a company that can produce the products you need. This enterprise must have an export food production enterprise registration certificate, and the certificate is valid and the certified product range includes the products you want to produce. Next, you need to design the label of your product, and then go to the quarantine bureau to apply for the export food label audit certificate and submit the inspection of the beverage you want to export. Generally speaking, if there is an order, you can export it first (only valid for the label, because the label can be considered as qualified within the acceptance range, and it is best to label it according to the requirements of the quarantine bureau. You can consult the local inspection bureau specifically, and it's no big deal to spend some money to treat you. Then, discuss the required quality and hygiene standards, delivery date, technology or formula confidentiality of your product. Sign a processing agreement with the processing enterprise for you, then implement it, and let this enterprise apply for inspection on your behalf (if you and this enterprise are not in the jurisdiction of the same quarantine bureau), then obtain the export certificate or the certificate required by the customer, and then go to the export quarantine bureau to go through the export customs clearance formalities or find the customs broker yourself.
That's basically all. It's troublesome anyway, but as long as you have money, it's sometimes easy to do things.
