Every year, thousands of hardware makers outside the United States watch their product take off on Amazon’s US marketplace and hit the same wall: the account, the payouts, and the tax paperwork all get simpler with an American company behind them. Do you actually need a US entity to sell into the US, and if you form one, what does it change on the operations side?The short answer: you can start selling on Amazon US as a foreign individual, but sellers who scale usually end up forming a US LLC anyway, and the ones who do it early avoid a painful account migration later. What an Amazon FBA LLC actually changesAmazon accepts sellers from dozens of countries as individuals or foreign companies. Seller accounts attached to a company survive personal life changes, travel, and bank switches far better than accounts tied to a person. Migrating an established account from personal to business identity later is possible but risks triggering re-verification at the worst possible time.
