Illicit trade is the production or distribution of a good or service that is considered illegal by a legislature.[1] It includes trade that is strictly illegal in different jurisdictions, as well as trade that is illegal in some jurisdictions but legal in others.[2]
Illicit trade can occur either in black markets or in legitimate markets. Some of the most important types of illicit trade include various forms of smuggling, the illegal drug trade, counterfeiting, human trafficking, the illicit tobacco trade, arms trafficking, illicit trafficking of cultural property, and various environmental crimes such as illegal wildlife trade, illegal logging and illegal fishing.
