No.
The United States does not ban guns, but it does not say it can sell bombs. If you want to sell, you must apply for an industrial and commercial business license and fill in "explosives" in the "business scope". It cannot be sold casually and must only be used for civil engineering purposes and not for military or other purposes. This is the same as gun sales in the United States, which only sell guns for civilian use and not for military use. Obviously the explosive you invented is definitely not for military use. Besides, someone has to buy it, right? Therefore, before opening a company, you must hold a press conference and shoot an advertisement to promote the company.
