3.1. Data description
Import Price Index (IPI) measures the performance of transaction prices of imported industrial products to be sold to the domestic market. All data under this heading are index data. Percentage changes are available (quarterly and annual). The index data are presented as quarterly and annual data.
3.2. Classification system
The classification used for these statistics is the Statistical Classification of Economic Activities NACE Rev.2. Import Prices are collected and processed and are published on the basis of the Classification of Products by Activity (CPA 2008). Goods are classified into individual CPA activities from the field of products (classes, groups, divisions, subsections and sections). Products are classified by activity in which they are imported. Classification of products by activity in which they are imported allows accordance between classification CPA 2008 and NACE Rev.2.
3.3. Coverage - sector
Data collection is done according to Regulation 1165/98 which was adopted in 1998 and amended in 2005 by Regulation 1185/2005. The data are published at 2-digit level of the NACE classification an EU standard classification of economic activities.
Classification of Product according to Economic Activity 2008:
Section B: 05- 09 Mining and quarrying
Section C: 10-34 Manufacturing
Section D: 35 Electricity, gas and steam supply
Section E: 36-38 Water supply, sewerage and waste.
3.4. Statistical concepts and definitions
Import Price Index measure changes in the prices of imports. Import is every product that was not produced in Albania but imported from a third country or supplied from another. The relative price is the simplest index of the price change in percentage of a product in two given time periods, one of which constitutes the base period.
Weights: The arithmetic weighing average of elementary indices of individual products will form the index. The index compares current year prices with the prices of December of the previous year (short-term - link) for the 6-digit level according to NACE Rev.2 is calculated by multiplying each item's weight at 6- digit level at the corresponding relative price and dividing their amount by the weight amount. The base period of the Index is the period for which the index is equal to 100. The price reference period is the period for which the price information for the calculation of the index is obtained. The weights reference period is the period to which the information on building the weights of the products is referred.

Published data will be considered final and they cannot be changed.
18.1. Source data
The sources for selecting enterprises are the Annual Survey on Industrial Production and Custom Data.
18.2. Frequency of data collection
Data is collected quarterly with monthly information.
18.3. Data collection
Prices which are the basis for calculating Import Price Indices are collected with the quarterly survey of Import Price. Regular collection of prices data normally flows from a sample of units and a sample of their imported products. Enterprises fill the questionnaires every quarter with the information for each month by interview face to face. Each questionnaire is prepared for the enterprise individually.
18.4. Data validation
Verification of prices: Collected import prices will be compared to their historical trend, price changes for similar import products and other knowledge gained by analysts; implausible price changes are verified with the reporting unit. Reporting units verify prices of the import products by reporting prices for both the current and the previous month and, if any changes occurred, those changes have to be explained in the questionnaire. In INSTAT, prices have been checked by checking prices on questionnaires, by data entry and by telephone in cases when the questionnaire is not properly completed.
18.5. Data compilation
National level:
First step is collecting information from the interviewers. The purpose is to bring this information to the statistic level. This process follows:
Physical control of questionnaires
Logical control of questionnaires (control of logical marked of responses indicators, description and codification of activity, and control of accurate values.)
Editing process of data collected (errors and modification)
Non response units and the missing information need to be completed through the imputation process
Analysis of results under each domain of publication.
18.6. Adjustment
Missing prices: In case of a missing price, the price of the previous month is carried forward.
Treatment of products out of production: If a product becomes unavailable, an appropriate replacement item is selected with similar specifications.
Selection of replacement items: A new item within the product group (CPA 6- digit) is suggested by the respondent and selected.
Adjustments for quality differences: Overlap pricing - collection of previous period price of the new item or judgmental explicit valuation of the specification difference. If none of the two are possible “no price change” is assumed.
New Products: New products are included at the end of the year and are part of the sample for the following period. Introducing new products: New products are included as from each new annual link.
Seasonal items: The latest observed price is carried forward until the item reappears on the market.
Indices are not seasonally-adjusted: Not applicable.
No further comments.
