Need Help with Licenses for Importing and Selling on Amazon

Hello, I’m planning to buy phone screen protectors from China and resell them on Amazon in Georgia. This is my first time doing this, so I’m unsure if I need any special licenses. I’ve searched online, but I’m getting mixed information. My order will be around $200 worth of phone protectors. Do I need to handle customs and border protection paperwork as well? Any advice on what licenses I need would be greatly appreciated.

And also need help to choice the business type when I’m making account amazoon asks me to choose one : an individual business or state own business or publicly listed business or privately owned business. I assume it’s privately owned business
