If you are going with a private label then trademark is mandatory. You can list your product by using UPC code which we provide and after that, you can apply for a trademark.
When you buy a product from the manufacturer you need private label product with your brand name or you are authorized to sell that product with your name. Make sure they provide you authorization letter on their company letterhead.
After getting authorization letter go for brand registry and for a trademark. You need to get Trademark with your brand which should be unique and then you can provide trademark document to Amazon which will lock all your listing for existing sellers.
For further queries, you can revert back to us.
Thanks & Regards,
