The top uranium importing countries are currently the United States, China, and France. These countries rely on imported uranium to fuel their nuclear power plants and meet their domestic energy needs.
In most countries, purchasing uranium is highly regulated and typically only available to government agencies and approved users for peaceful purposes such as nuclear energy and medicine. It is illegal in many places to possess or trade uranium without proper authorization due to its potential for misuse in weapons or other harmful activities.
It is illegal in most countries to sell uranium without proper licensing and permits. If you have legitimate uranium to sell, you would need to comply with all relevant laws and regulations, and likely work through government-approved channels or vendors in the nuclear industry. Selling uranium on the black market or without proper authorization poses serious legal and safety risks.
