Methodological Note on Statistical Data
on Imports and Exports by CPA 2
This publication contains external trade data broken down by CPA 2 and data on imports and exports for the purpose of and after inward and outward processing according to CPA 2.
The source of data on imports and exports are customs statistics collected by the Directorate General of Customs from data reported in Singe Administrative Documents.
Imports and exports data should be regarded as preliminary ones. Data published are quartely updated by those Single Administrative Documents (SAD) that were not included into the previous process-ing for one reason or another. As soon as these SADs get into process-ing, they are always included into the period when the goods indicated on the SAD were cleared. Data published by individual quarter will be subse-quently updated.
In order to achieve a better explanatory power and comparability of data between external trade statistics, enterprise statistics and national accounts, data have been converted according to the structure of the Classification of Products by Activity (CPA) down to the two-digit level.
