Domestic Trade Statistics gathers information on the movement of commodities in the country. It is a compilation of administrative data on commodities carried through different transport systems in a country. However, in the Philippines, the Philippine Statistics Authority (PSA) compiles domestic trade carried through air and water only. The domestic trade carried through rail are excluded due to the discontinuance of cargo operation of the Philippine National Railways (PNR). Moreover, the PSA is currently studying the conduct of survey to gather domestic trade statistics for land mode of transport. Refer to Sections I.3 and I.4 for the detailed coverage and limitation of the domestic trade statistics.
