Opening a wine company in USA with importing and distributing licence
To answer your questions I would need some more information. For example, what state is the third party warehouse located in? If you haven't decided yet on one then what are your ideas about it (you probably did some research by now).
Another question to ask is will this business be an importer and a wholesale distributor only, or you also have plans to sell in retail? Since liquor is heavily regulated, there will be lots of licensing involved, but first we would need to understand the scope of your business, and only then advise further.
You are welcome to email us with your answers and other questions, and we will see how we could help you set it up properly.
