To date, research on the economic history of Brazil during the 19th century has relied on official foreign trade statistics, the accuracy of which has repeatedly been put into question. This paper provides insights into the accuracy of the official series by examining the accuracy of the export and import series for Brazil during the 19th century. We re-estimate the official import series using trading partner sources, and find that the official series was marginally under-valued during certain periods of the 19th century. Furthermore, we provide new upper- and lower-bound estimates of the export series by testing different assumptions regarding the size of the cost, insurance and freight to free on board factor adjustments. Finally, we introduce a new import price index for the period 1827-1913.
