The system of warehousing dutiable goods and deferring payment of the duty until the goods were required for home consumption began in 1714. In that year tobacco was allowed to be deposited free of duty in specified warehouses. To begin with, the Treasury may by order specify any area as a place where bonded warehousing facilities can be granted. Then the Customs and Excise authorities may sanction any place within the area as bonded premises. Warehouses may be public or private; that is, they may be owned and managed by professional warehouse-keepers for storing other people's goods, or they may form part of the premises of an individual for storing his own goods. The term 'private warehouse' is extended to storage premises limited to the use of a particular firm or group of persons engaged in one trade.
