Daniel William Aston faces a potential jail sentence and extradition.
His firm, Trod Ltd, also faces a fine of up to $100m after it was targeted in a FBI-led operation last month.
The criminal case centres around the company’s business of selling wall posters to American customers on the Amazon website.
The investigation saw West Midlands Police carry out raids at the businessman’s home and the Rubery based firm in December.
Mr Aston has since been charged with price fixing by the US Justice Department in violation of the Sherman Act, which carries a maximum imprisonment sentence of 10 years and a fine of $1m.
His company, Trod Ltd, which also trades as Buy 4 Less, Buy For Less, and Buy-For-Less-Online is also charged with one count of price fixing, which carries a maximum £100m fine.
The firms sell a wide range of items including posters revolving around Star Wars, The Simpsons and The Walking Dead.
It is unconfirmed which posters are involved at the centre of the allegations, which are said to involve pricing algorithms.
