Press release

The foreign trade indexes 2010 = 100 published by the Finnish Customs, i.e. unit value index and volume index, have contained incorrect figures

Errors have been located both in the export and the import unit value and volume indexes for the period of February 2011 to March 2015 at the CPA2 level. These figures have been available for users in the foreign trade statistics database Uljas from March 2013 to June 2015. The incorrect figures have also been published in the Monthly statistics on the foreign trade of goods publication from January 2013 to March 2015. The errors have been present in the following tables of the publication:

Table 9. Volume index, exports 2010=100
Table 10. Volume index, imports 2010=100
Table 11. Unit value index, exports 2010=10
Table 12. Unit value index, imports 2010=100

The errors have been present at the point figures and the point figure averages only at the CPA2 level.
Also, the changes of monthly, annual and the moving averages have been incorrect. The point figures of all general indexes and CPA3 level indexes have been correct.

The monthly CPA2 level figures and their averages published in the Uljas database were erroneous from February 2011 to March 2015. Also, the Uljas database contained errors in the following indicators: monthly change, annual change, effect, moving 12-month average and annual change of the moving average. The erroneous data was first published in March 2013. The data of all the other indexes have been correct.

The website of the Finnish Customs also has Excel spreadsheets, which contain the point figures of the indexes. In these tables there has been incorrect information at the CPA2 level for the above mentioned period. The errors have been corrected. The tables are available from the link below: tulli.fi/en > Statistics > Tables > Indexes .

The incorrect figures are due to a reference error in the new chain linking method used in the statistical production process. The corrections substantially affect the monthly point figures of the CPA 02 level

The Uljas statistical database has been updated with the corrected figures 30.6.2015
