Explanation:

Dual distribution is a situation where a manufacturer decides to distribute their products directly (using their own distributors) and, at the same time, hire independent distributors (who have no ownership relationship with the manufacturer).

Dual distribution derives its name from the fact that two means of distribution are used simultaneously: one of its own and one contracted. It is a mixture of the two basic distribution options that a manufacturer has: to integrate vertically and assume all distribution activities until reaching the final consumer or; outsource these activities and pay others to carry them out.
