The "external sector" referred to in the United Nations System of National Accounts (SNA) as the "rest of the world," plays an important part in the economy of nations, and indeed, as countries become more developed, its role tends to increase. This role is attributed largely to the international exchange of goods and services but mainly to merchandise trade. The purpose of this document is to define merchandise trade and to describe the various sources and methods of estimate in respect of the relevant items of the SNA, namely, exports and imports of merchandise.
