Brand Approval by Seller

What is the purpose of brand approval? Is it to prove the brand / product exists?

I am sourcing a product from a brand that operates in a foreign country and is not on Amazon. I want to use Brand Approval as a seller to list the product associated with the brand. I’ll take pictures of the product as requested.

I assume this will get the brand added to Amazon. And other sellers will also be able to sell products by this brand. I don’t intend to make any claim of brand ownership by going through the Brand Approval process.

Is this acceptable? Should I also proactively obtain a letter of authorization from the manufacturer stating they allow me to sell their products on Amazon?
