International trade in goods and services are on a balance of payments basis. Based on the Fifth Edition of the International Monetary Funds Balance of Payments Manual (BPM5, 1993). Goods comprise the largest category of transactions that involve changes of ownership between residents and non-residents. In addition to general merchandise, which covers most movable goods, the category includes: the movement of goods for processing, the value of repairs of goods and goods procured in ports by non-resident carriers. Services covers items such as travel, transportation, communications, financial and computer service, royalties and license fees and many other business services.
