Dealing in Explosive Materials Without License is the illegal trafficking of explosive materials such as dynamite, blasting caps, gunpowder, or any other materials that are combustible or explosive. It is a serious crime in most countries, as these materials can be used in terrorist activities, or for unlawful purposes. The penalties for this crime vary from country to country, but typically include hefty fines and long prison sentences. There are two types of Dealing in Explosive Materials Without License: commercial and non-commercial. Commercial deals involve the sale or transfer of explosives for profit. Non-commercial deals are usually for personal use or hobby purposes.
