Country Experience: Mexico: Administrative and company records (ch. 3)

3.27.        Example from Mexico: administrative and company records as non-customs sources. In principle, administrative and company records can be used to validate, supplement or replace the information provided by customs. In the case of Mexico, such non-customs records are used for two specific cases. In the first case, the Ministry of Communications and Transportation provides information on the volume of goods transported by air, sea, road and rail obtained from national and international airlines as well as from public bodies such the maritime ports. This information is used to supplement the information on mode of transport available from customs declarations. Second, in the case of oil,Mexico’s Working Group on Foreign Trade Statistics agrees on the replacement of the customs records and the use of internal records from Petroleos Mexicanos, the company responsible in Mexico for producing and exporting oil.
