Outward processing (OP) activities play an important role in Hong Kong's trade with the mainland of China (the Mainland). Trade of OP nature is mingled with other types of trade under the existing system of recording trade statistics. To better assess the performance of Hong Kong's trade with the Mainland, the Census and Statistics Department has been conducting monthly surveys to collect data on trade involving OP in the Mainland since 1988. The main objective of the surveys is to separate OP trade from the regular trade. Starting from 2010, additional data on the arrangement for OP in the Mainland was collected in the survey.
