Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

3.1. Data description
The Annual Survey of Industrial Products covers the data on the production and turnover of industrial products and services in terms of volume and value as well. Data of subcontracted operation are also available by products.
We distinguish two types of production: production on own account and sub-contracted production. So in the Hungarian PRODCOM questionnaire the data providers could report product data in two rows ("T" - total production and "B" - sub-contracted production).
All of our surveyed variables are available for both types of production.
Surveyed variables are the following:
Total Quantity produced
Quantity sold
Net sales value of industrial products and services broken-down by domestic and export sales.
Registration tax, excise duty and public health product tax
According to the EBS Regulation in the PRODCOM data transimmison file the production under sub-contracted operations shall be completely separated from the sold production varibale. With the Hungarian indicators available from our questionnaire, all the required new variables could be produced.
3.2. Classification system
The Hungarian Classification of Industrial Products (ITO) is a hierarchical classification containing products and services. (ITO'22 structure file is attached.)
ITO is the domestic version of PRODCOM list issued by Eurostat, it is applied from the 1st of January 2008 and it is used for observing industrial products and services.
The structure of the 12-digit codes:
1-4th digits identical with the Statistical Classification of Economic Activities in the European Community (NACE Rev.2.)
1-6th digits identical with the Classification of Products by Activity (CPA)
7-8th digits corresponding to PRODCOM, in case of “HU” items codes are formed by HCSO
9th digit is a further possibility for special domestic breakdown
The data suppliers of the “Annual statistical survey of production” are industrial enterprises selected by size classes of staff, furthermore, enterprises classified outside industry, with a more than 500 million HUF turnover from industrial activities or having run an industrial kind-of-activity unit (KAU) in the previous year.
From enterprises classified to industry the following are selected to report annually on industrial production: all enterprises with 20 or more employees, and in some cases enterprises having 5-19 employees are observed as well. The aim of the selection is to cover at least 90% of the industrial production of each class.
Non-industrial enterprises are observed if they reported industrial turnover more than 500 million HUF in the annual survey on performance statistics (SBS).
Non-industrial enterprises with industrial KAU.
Furthermore, some individually selected non-industrial enterprises having significant industrial sales and based on their principal activity classified to trade (for example hypermarkets).
3.4. Statistical concepts and definitions
Total production of industrial products: the data of products produced by the enterprises classified into the industry, respectively those of produced by the enterprises classified out of industry according to the structure of Classification of Industrial Products (ITO).
Total sales: the net sales value of industrial activities
Export sales: value of the sales of own-produced industrial products and industrial products produced by subcontractors effectuated in the turnover of external trade to foreign buyers, respectively, as well as the current HUF value of the industrial services provided to foreign buyers, paid with foreign exchange, import purchase or HUF. The export sales are defined as sales over the border of Hungary. Export sales include the dispatches to the Member States of EU, too. Sales for enterprises with Hungarian tax number, but having headquarters of abroad have to be accounted as export sales.
Domestic sales: value of the sales of own-produced industrial products and industrial products produced by subcontractors effectuated in the turnover of domestic trade as well as the value of the industrial services provided at home. The domestic sales are defined as sales within the border of Hungary. Value of the sales to enterprises operating on custom free zones and from enterprises operating on custom free zones to enterprises operating at home are accounted as domestic sales.
Sub-contracted operation: In case of sub-contracted opeartions the sub-contractor performs certain techonolgical processes and operations on the material or semi-finished product provided by the principal. The material and semi-finished product taken over for the sub-contracted work is not purchased by the sub-contractor, but remains the property of the principal. The production of a new product can be considered if the sub-contractor carries out the entire technological process, all the operations of converting the material into a finished product. An item is defined to be a new product if the PRODCOM code of the received material and the new product are different. According to the EU regulations, the production of a new product carried out under sub-contracted operation is considered as production of a new product. Consequently the production and sales data of these product should be reported as product data not as service. Only the partial machining under sub-contracting agreement could be taken into account as service. We distinguish two types of production: production on own account and sub-contracted production. So in the Hungarian PRODCOM questionnaire the data providers could report data in two rows ("T" - total production and "B" - sub-contracted production where "B" is part of "T"). We have information about the sub-contracted data, but we do not have information about the sub-contracted relationship.
3.5. Statistical unit
Currently the observation unit in Hungary is the legal unit.
The data providers of the “Annual survey of industrial products” are industrial enterprises selected by size classes of their number of employees, furthermore enterprises classified as non-industrial with a more than 500 million HUF turnover from industrial activities or having run an industrial kind-of-activity unit (KAU) in the previous year.
3.6. Statistical population
The frame of observation is all enterprises classified to industry (divisions from 05 to 35 of NACE Rev.2), as well as non-industrial enterprises pursuing industrial activities too, recorded in the Business Register. The surveys must include all undertakings employing at least 20 employees. The other quality criteria is that data from undertakings should represent at least 90% of national production by NACE classes. To reach this criteria, we have to ask smaller enterprises than 20 employees in almost the half of the NACE classes.
Number of enterprises involved in the annual PRODCOM survey according to size:
Size classes (in 2024)
Number of enterprises involved in the annual PRODCOM survey
20 and more employees
5154
10-19 employees
2442
5-9 employees
1115
less than 5 employees

Total
8714
119 classes (out of 244) are over 90%, asking undertakings over 20; 109 classes are about 90%, asking undertakings over 10; it depends on the structure of the class.
3.7. Reference area
At national level: the whole country. (We do not apply any reginal breakdown.)
3.8. Coverage - Time
Data are available from 1996 onwards. There was a change in the domestic nomenclature in the year 2008 (BTO was changed for ITO).
Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics, repealing 10 legal acts in the field of business statistics (Text with EEA relevance)
All the non-confidential data are available on Eurostat dissemination website. Selected data are transmitted annually (in April) to the UN. There are also other ad-hoc data sharing at European level.
7.1. Confidentiality - policy
At European level: Regulation (EC) No 223/2009 on European statistics(recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.
Eurostat offer passive confidentiality (as a possibility) – MSs applying passive confidentiality, have a much better transparency degree, offering more comprehensive information for all users.
In Hungary the data protection is under superior regulation (Act No. CLV of 2016 on Official Statistics), we cannot apply passive confidentiality.
We apply active confidentiality. General rule is that data are disclosed only if there are at least 3 reporting companies. In case of 3 or more data providers, data are public, with less than 3 respondents data are confidential. On the questionnaire there is a tic box with the question “I agree to disclose of my reported data by Central Statistical Office in accordance with the Law on Statistics. This contribution means knowledge of details”. If the respondent agrees with the disclosure of their data, data are public. In case of one respondent there is no problem, in case of two respondents data are only public if both of them agrees with the disclosure.
The percentage of confidential data could be recorded after the final PRODCOM data transmission, so in the beginning of October.
We have got data for 2188 PRODCOM codes, and (without the breakdown of the sub-contracted operation) there are 775 confidential PRODCOM codes. So 35% of the PRODCOM codes are confidential in Hungary.
Without asking contribution of the data provider (mentioned above) the rate of the confidential data whould be higher with 20%.
8.1. Release calendar
Annual preliminary data are available from 30 June, final data from 30 September.
After data transmission to Eurostat, data are made available (at domestic level) at Statinfo website.
Release calendar is for internal use, there is no public accessibility.
8.2. Release calendar access
There is no public accessibility to the release calendar.
8.3. Release policy - user access
In line with the Community legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 - 'Accessibility and clarity') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users.
European level: annual
National level: annual
10.1. Dissemination format - News release
There is no press releases linked to the data industrial products.
Detailed methodological information on national methodologies is available on national website (Data/ Metainformation/ Statistical Domains by subject/ Economic statistics/ Business statistics/ Industrial products).
Since the year 2012 the data of suppliers have been entered via ELEKTRA system of HCSO.
The aspects of data validation are built into the data entry system already at the level of respondents, and they are updated generally once a year.
Our colleagues responsible for data collection use an intelligent data validation system (Data Entry and Validation System (ADEL)) for checking of questionnaires provided electronically.
During the macro-validation procedure we compare the aggregated data with indicators of the same content, arising from different sources, and investigate the deviations.
We check the completeness of quantity and value data. Product-level data of an enterprise are compared to those of the previous year, while the average product price of the enterprise to the average domestic price.
We check the coherence with other statistics.
Product data are compared to:
cumulative monthly product data (the variable of „total production”), as well as,
STS (Short-term statistics) data,
annual performance statistics.
The 100 largest Hungarian industrial enterprises are checked according to strict rules (the deviation can be a maximum of +/- 10%, as compared to +/- 20% in case of smaller enterprises).
11.2. Quality management - assessment
The general quality of data is very good due to built-in validation standards.
After the introduction of the on-line data collection the quality is improving yearly due to continuous development system (depending on practical experience).
This year the deadline for the annual report was 31 May as usual, so we were able to perform the data consistency test with tax data for all data providers.
12.1. Relevance - User Needs
Main users of annual survey of industrial products are:
1. Domestic data users:
government authorities, organs of public administration (central and local)
trade associations, research institutions, students
enterprises
media
2. Foreign data users:
international institutions (UN, EUROSTAT)
US Geological Survey (US Minerals)
3. Data users within the HCSO:
national accounts use product data for the supply and use table
the industrial producer price index uses product data for its weighting system
12.2. Relevance - User Satisfaction
User satisfaction is measured by a survey sent to the significant data users. The Dissemination Department is responsible for the survey.
12.3. Completeness
Annual product statistics are one of the most demanded industrial statistics. Users usually need as detailed product statistics as possible.
The only barrier to publishing product data is the confidentiality of data. The following variables are available both for own-produced and for sub-contracted produced products:
total production (in quantities)
sold quantities (export and domestic)
sales values (export and domestic)
13.1. Accuracy - overall
PRODCOM is essentially a cut-off sample. In theory, the Regulation (EU) 2022/2552 of the European Parliament and of the Council of 12 December 2022 on European business statistics, repealing 10 legal acts in the field of business statistics (Text with EEA relevance) prescribes that surveys must include all undertakings employing at least 20 employees. Small enterprises with less than 20 employees are exempted.
The other quality criteria is that data from undertakings should represent at least 90% of national production by NACE classes. To reach this criteria, we have to ask smaller enterprises than 20 employees in about the half of the NACE classes.
Number of enterprises involved in the annual PRODCOM survey in 2024 reference year:
Size classes (in 2024)
Number of enterprises involved in the annual PRODCOM survey
20 and more employees
5154
10-19 employees
2442

Total
8714
119 classes (out of 244) are over 90%, asking undertakings over 20; 109 classes are about 90%, asking undertakings over 10; it depends on the structure of the class.
13.2. Sampling error
As mentioned at previous sub-chapter, theoretically the small enterprises with less than 20 employees are exempted from the sample.
In practice to reach the 90% rule, we have to inquire also enterprises with less than 20 employees.
In a few NACE classes, meeting the 90% criteria would be multiple burden to SMEs (where the majority of enterprises are around 5 employees, e.g. NACE classes in the 16 sector). In these cases (especially if the weight of the NACE class is low) we do not reach the 90%.
13.3. Non-sampling error
Response rates:
Response rates are calculated based on the number of enterprises and also weighted by the sales of enterprises. The response rate was 84% (the gross sample size in 2024 was 8714 enterprise, while the net sample was of 7330).

All enterprises
Of which: those with ≥ 20 employees

Non-sampling errors:
In general the occurrence of other non-sampling errors is very low since the introduction of Elektra system (on-line data collection). The aspects of data validation are built into the data entry system already at the level of respondents, and they are updated generally once a year. Detailed checking of data and correction of errors is not automatic. This requires the cooperation between our colleagues responsible for data collection and the data providers.
Over-coverage rate: 0,4%
One of the quality criteria of the data collection is that data from undertakings should represent at least 90% of national production by NACE classes. To reach this criteria, we have to ask smaller enterprises than 20 employees in about the half of the NACE classes. In every five years, we examine the fulfilment of this criteria and determine the size classes of data providers to be selected for data collection according to the sector. For this reason, there are some cases where companies should not have been designated.
Under-coverage rate: It is not applied. As data collection is comprehensive (as detailed in 3.3 coverage - sector) and the designation for participate in the data collection takes place at the end of the reference year, this indicator is not relevant.
Unit non-response (in case of all enterprises): 1,6%
Item non-response rate: It is not applied. We have an online survey so if data providers report data under a certain PRODCOM code, all necessary indicators should be filled. For example: data provider reported domestic sales value, they should report also domestic sales quantity under the certain PRODCOM code.
Multiple listing: No units are present more than once in the frame. Each company has a unique tax number that identifies it so avoiding multiple assignments.
Imputation:
Number of imputation (in case of all enterprises): 1,4%
Number of imputation (in case of sub-contracting enterprises): 0,7%
The proportion of the sub-contracting enterprises: 6,4%
14.1. Timeliness
Annual preliminary data are available from 30 June (6 month after the reference period), final data from 30 September (9 month after the reference period).
14.2. Punctuality
Both preliminary and final data releases were delivered in due time.
15.1. Comparability - geographical
There are no problems of comparability between the Member States. All country reports their data based on PRODCOM list, in the defined unit measures.
We do not make any national report according to the industrial production of the different regions. In case of most product codes, a county-level breakdown would result in a multiplication of our confidential data.
15.2. Comparability - over time
The Hungarian national nomenclature changed in the year 2008 (from BTO to ITO). From 2008 we have comparable time series.
From 1998 we could compare time series using correspondence tables between BTO and ITO (the former and the present national nomenclatures).
PRODCOM data reporting: Two industrial production variables were required by the first PRODCOM Regulation: sold production and total production. According to the EBS Regulation in the PRODCOM data transmission file the production under sub-contracted operations shall be completely separated from the sold production variable from the reference year 2021. We have collected separately the total production data and sub-contracted data. The PRODCOM data production methodology has been modified to comply with the new EBS requirements from the reference year 2021.
15.3. Coherence - cross domain
Product data are compared to:
cumulative monthly product data (the variable of “total production”), as well as,
STS (Short-term statistics) data,
annual performance statistics.
The 100 largest Hungarian industrial enterprises are checked according to strict rules (the deviation can be a maximum of +/- 10%, as compared to +/- 20% in case of smaller enterprises).
15.4. Coherence - internal
Any lack of coherence in the output is impossible, because of the structure of the data collection and the on-line data collection system.
Data provider should fill in only primary data, summing up and further calculation prepared by statisticians.
In case of data collections designated in the Annex to Government Decree No 388/2017 (XII. 13.) on the extension of electronic data collection for statistical purposes, the data must be provided via the IT system designed for this purpose. Using the KSH-ELEKTRA electronic data collection system, the required data can be provided without paper, with an internet connection and in strict compliance with modern data protection guidelines. Since 1 January 2012, the data of the data providers have been entered via ELEKTRA system of HCSO. Product data supplied in the previous year had been pre-printed on the questionnaire until 2011, and have been pre-filled since 2012. The pre-filled questionnaire reduces the time needed for completion, thus the burden of the data providers.
The aspects of data validation are built into the data entry system already at the level of respondents, and they are updated generally once a year. Detailed checking of data and correction of errors is not automatic. This requires the cooperation between our colleagues responsible for data collection and the data providers.
We do not have any information about the exact costs of the PRODCOM statistics.
17.1. Data revision - policy
Scheduled revision
Routine revision
In June the published data for previous year are preliminary for Eurostat, the final data can differ from preliminary data at the end of September because of data corrections. Reported data for the previous year are checked systematically by regional departments between 1 June and 21 July. The data are compared with data of Annual and Monthly Performance Statistics reports, as well.
Additionally our colleagues responsible for data collection review the data in August and they ask for explanations for the extreme changes from enterprises through regional departments and if it is necessary, data will be modified. In this period it can turn out the necessity of data correction of previous years’, as well.
The corrected finalized data are published at the end of September.
Major revision
There are no planned revisions. In case of changes in nomenclature we do not perform major revisions, figures can only be used in the nomenclature of the year. In case of nomenclature changes data from different years can be compared with help of correspondence tables.
Non-scheduled revision
This can happen in exceptional cases if an unforeseen event requires some data reviews (big data errors, technical problems, etc...). Non-scheduled revisions have not been conducted in the recent years.
17.2. Data revision - practice
In practice we do everything just like in the revision policy.
The data correction is still in progress. Revised data are available for final data transmission.
18.1. Source data
Data set is based on a cut-off sample survey via an on-line data collection system called Elektra. Data providers should fill in pre-listed templates. Rows of the nomenclature (national version of PRODCOM, called ITO) are pre-filled specific for the enterprise.
The gross sample size in 2024 was of 8.714 enterprises, while the net sample was of 7.330.
18.2. Frequency of data collection
Annual (reference period: calendar year)
18.3. Data collection
Data are collected via electronic on-line survey, at Elektra website.
The questionnaire can be found in the Annex (see below in the Annexes section).
18.4. Data validation
Since January 1, 2012, the data of suppliers have been entered via ELEKTRA system of HCSO.
The aspects of data validation are built into the data entry system already at the level of respondents, and they are updated generally once a year.
The colleagues responsible for data collection use an intelligent data validation system (Data Entry and Validation System - ADEL) for checking of questionnaires provided electronically.
During the macro-validation procedure we compare the aggregated data with indicators of the same content, arising from different sources, and investigate the deviations.
We check the completeness of quantity and value data. Product-level data of an enterprise are compared to those of the previous year, while the average product price of the enterprise to the average domestic price.
Data are revised in September in order to correct detected errors.
18.5. Data compilation
Imputation
In case of non-responses respondents are contacted by telephone or e-mail.
Imputation may be necessary not only in case of unit non-response but also in case a particular item is missing. The most frequently used source of imputation is the report of the missing enterprise in the previous period.
An additional source of imputation may be the sales structure reported for the same reference period in the annual economic statistical survey, broken down by TEÁOR (NACE) classes. Class-level sales of an enterprise are broken down into product groups based on the domestic structure of industrial production.
Missing volume data of each product group are estimated from sales data, using the average domestic price of the particular product group.
Data on dead and non-operating units, as well as returned questionnaires containing no answers are not imputed.
18.6. Adjustment
We do not use any adjustment.
If we detect an outlier we contact the data provider and ask about the reasons. The data provider could modify the outlier or justify and confirm it.
Questionnaire of the data collection can be found in the Annexes below.
The Annual Survey of Industrial Products covers the data on the production and turnover of industrial products and services in terms of volume and value as well. Data of subcontracted operation are also available by products.
We distinguish two types of production: production on own account and sub-contracted production. So in the Hungarian PRODCOM questionnaire the data providers could report product data in two rows ("T" - total production and "B" - sub-contracted production).
All of our surveyed variables are available for both types of production.
Surveyed variables are the following:
Total Quantity produced
Quantity sold
Net sales value of industrial products and services broken-down by domestic and export sales.
Registration tax, excise duty and public health product tax
According to the EBS Regulation in the PRODCOM data transimmison file the production under sub-contracted operations shall be completely separated from the sold production varibale. With the Hungarian indicators available from our questionnaire, all the required new variables could be produced.
31 January 2025
Total production of industrial products: the data of products produced by the enterprises classified into the industry, respectively those of produced by the enterprises classified out of industry according to the structure of Classification of Industrial Products (ITO).
Total sales: the net sales value of industrial activities
Export sales: value of the sales of own-produced industrial products and industrial products produced by subcontractors effectuated in the turnover of external trade to foreign buyers, respectively, as well as the current HUF value of the industrial services provided to foreign buyers, paid with foreign exchange, import purchase or HUF. The export sales are defined as sales over the border of Hungary. Export sales include the dispatches to the Member States of EU, too. Sales for enterprises with Hungarian tax number, but having headquarters of abroad have to be accounted as export sales.
Domestic sales: value of the sales of own-produced industrial products and industrial products produced by subcontractors effectuated in the turnover of domestic trade as well as the value of the industrial services provided at home. The domestic sales are defined as sales within the border of Hungary. Value of the sales to enterprises operating on custom free zones and from enterprises operating on custom free zones to enterprises operating at home are accounted as domestic sales.
Sub-contracted operation: In case of sub-contracted opeartions the sub-contractor performs certain techonolgical processes and operations on the material or semi-finished product provided by the principal. The material and semi-finished product taken over for the sub-contracted work is not purchased by the sub-contractor, but remains the property of the principal. The production of a new product can be considered if the sub-contractor carries out the entire technological process, all the operations of converting the material into a finished product. An item is defined to be a new product if the PRODCOM code of the received material and the new product are different. According to the EU regulations, the production of a new product carried out under sub-contracted operation is considered as production of a new product. Consequently the production and sales data of these product should be reported as product data not as service. Only the partial machining under sub-contracting agreement could be taken into account as service. We distinguish two types of production: production on own account and sub-contracted production. So in the Hungarian PRODCOM questionnaire the data providers could report data in two rows ("T" - total production and "B" - sub-contracted production where "B" is part of "T"). We have information about the sub-contracted data, but we do not have information about the sub-contracted relationship.
Currently the observation unit in Hungary is the legal unit.
The data providers of the “Annual survey of industrial products” are industrial enterprises selected by size classes of their number of employees, furthermore enterprises classified as non-industrial with a more than 500 million HUF turnover from industrial activities or having run an industrial kind-of-activity unit (KAU) in the previous year.
The frame of observation is all enterprises classified to industry (divisions from 05 to 35 of NACE Rev.2), as well as non-industrial enterprises pursuing industrial activities too, recorded in the Business Register. The surveys must include all undertakings employing at least 20 employees. The other quality criteria is that data from undertakings should represent at least 90% of national production by NACE classes. To reach this criteria, we have to ask smaller enterprises than 20 employees in almost the half of the NACE classes.

Year 2024
PRODCOM is essentially a cut-off sample. In theory, the Regulation (EU) 2022/2552 of the European Parliament and of the Council of 12 December 2022 on European business statistics, repealing 10 legal acts in the field of business statistics (Text with EEA relevance) prescribes that surveys must include all undertakings employing at least 20 employees.

Data are disseminated in:
natural units, based on the PRODCOM list
national currency HUF (Hungarian Forint)
Imputation
In case of non-responses respondents are contacted by telephone or e-mail.
Imputation may be necessary not only in case of unit non-response but also in case a particular item is missing. The most frequently used source of imputation is the report of the missing enterprise in the previous period.
An additional source of imputation may be the sales structure reported for the same reference period in the annual economic statistical survey, broken down by TEÁOR (NACE) classes. Class-level sales of an enterprise are broken down into product groups based on the domestic structure of industrial production.
Missing volume data of each product group are estimated from sales data, using the average domestic price of the particular product group.

Data set is based on a cut-off sample survey via an on-line data collection system called Elektra. Data providers should fill in pre-listed templates. Rows of the nomenclature (national version of PRODCOM, called ITO) are pre-filled specific for the enterprise.
The gross sample size in 2024 was of 8.714 enterprises, while the net sample was of 7.330.
European level: annual
National level: annual
Annual preliminary data are available from 30 June (6 month after the reference period), final data from 30 September (9 month after the reference period).
There are no problems of comparability between the Member States. All country reports their data based on PRODCOM list, in the defined unit measures.
We do not make any national report according to the industrial production of the different regions. In case of most product codes, a county-level breakdown would result in a multiplication of our confidential data.
The Hungarian national nomenclature changed in the year 2008 (from BTO to ITO). From 2008 we have comparable time series.
From 1998 we could compare time series using correspondence tables between BTO and ITO (the former and the present national nomenclatures).
PRODCOM data reporting: Two industrial production variables were required by the first PRODCOM Regulation: sold production and total production. According to the EBS Regulation in the PRODCOM data transmission file the production under sub-contracted operations shall be completely separated from the sold production variable from the reference year 2021. We have collected separately the total production data and sub-contracted data. The PRODCOM data production methodology has been modified to comply with the new EBS requirements from the reference year 2021.
