Between 1717 and 1744 Wragg and Savage accounted for 36 slave ships and the importation of around 10,000 African slaves. Wragg's name appears 25 times in minutes of the Royal African Company concerning shipments of slaves from The Gambia between 1722 and 1727.

Henry Lieferman notes that "during the 1730s, for example, nearly 20,000 slaves, most of them from Angola, were imported through the city, almost a third of them by Joseph Wragg & Co., the biggest slave trader in town." For example, on 15 March 1738 Joseph Wragg & Co. sold 179 adults and 175 children taken from Angola aboard the slave ship "Shepherd." During the year 1735/1736 alone, Joseph Wragg imported 341 slaves from Africa, 6,230 gallons of rum from Antigua and Barbados, paid duties of 296 pounds on sundries imported from Philadelphia and Barbados, exported 6,095 deerskins to London and Bristol, exported rice and imported various English goods.
