3.1. Data description
The purpose of import price indices survey is to collect data on monthly price changes of industrial products from import. Price indices of industrial products from import represent important economic indicators which can be used as an inflation measure; as time series deflators, especially for the needs of national accounts and as a tool for adjusting prices when concluding various sales contracts.
3.2. Classification system
NACE Rev. 2, CPA Version 2008
3.3. Coverage - sector
Indices are calculated for the following sections of industrial activity: B (Mining and quarrying), and C (Manufacturing) according to NACE Rev. 2 classification.
3.4. Statistical concepts and definitions
Purchase price of industrial products from import is the price of a good delivered at the frontier of the importing country, including transportation costs, insurance charges, and any other costs incurred to that point (CIF price) that influence on the unit price of a product. Price indices of industrial products from import are relative numbers that show changes in producer prices from period to period. Price indices are calculated for certain products (individual indices), for groups of products and for all products included in the list (total index). The monthly index shows by how much on average prices in the current month changed in comparison with the previous month. The quarterly index shows by how much on average prices in the current quarter changed in comparison with the previous quarter. The annual index shows by how much on average prices changed in the last 12 months. The average annual index shows by how much on average prices changed in the last n months of the current year compared to the same period of the previous year.

The response rate is about 70%. Depending on their size or representatives, companies are contacted by phone in order to provide data on time. The price of the temporarily unavailable product is determined by contacting the company from which it is required to estimate/assess the missing price or to repeat the last declared price. In cases when the product of a certain quality for which the prices are collected is not imported, or if the product of that quality is "non-market goods" then a new product of the specified quality is defined, which is most imported and it is expected to be imported for a long time and in large quantities. Prices for the new selected quality product are given simultaneously for the current and previous month. Companies are obliged to explain any change in quality.

18.1. Source data
The main source of data for calculation of the price indices of industrial products from import is the Monthly survey on the prices of industrial products from imports. This survey includes companies - importers of industrial products covered by sections of mining and quarrying and manufacturing of the NACE Rev. 2 classification, with more than five employees that meet the unit of measurement prescribed by the Nomenclature of industrial products per unit of product. Sample and weights are based on foreign trade survey. The sample is determined by three criteria: selection of products with significant import values; selection of enterprises importing these selected products, selection of representative items in cooperation with the reporting units.
18.2. Frequency of data collection
Monthly.
18.3. Data collection
Reporting method is used for data collection. Questionnaires are filled by reporting units between the 14th and 16th of each month for the current month. Purchase price of industrial products from import is the price of a good delivered at the frontier of the importing country, including transportation costs, insurance charges, and any other costs incurred to that point (CIF price) that influence on the unit price of a product.
18.4. Data validation
Data validation is performed in accordance with the defined criteria for control. Validation is done before and after entering the data. Reporting units confirm product prices by entering the prices for the current and previous month and if any changes occur, they need to be explained in the questionnaire. In case of major deviations, reporting units are contacted. Calculated indices are also checked before publishing.
18.5. Data compilation
Import price indices are relative numbers that show changes in import prices from period to period. Price indices are calculated for certain products (individual indices), for groups of products and for all products included in the index list (total index). Product prices are used to calculate elementary indices and calculation of aggregate indices is carried out by weighting individual indices according to the Laspeyeres formula. For the purposes of this survey, the average price of products for the previous year is used as a base. Weights are based on foreign trade survey.
18.6. Adjustment
Adjustment of data is not made.
