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 PRODCOM survey provides information on industrial goods and services PRODuction of the European COMmunity in compliance with Regulation (EU) 2019/2152 of 27 November 2019 on European business statistics. The Czech Statistical Office is responsible for compilation of these statistics in the Czech Republic.
PRODCOM data are collected via survey 'Annual questionnaire on industry'.
3.2. Classification system
In the PRODCOM classification products are grouped by the NACE Rev.2, 4-digits industrial sectors, in which they are primarily produced (i.e. characteristic products). NACE Rev. 2 is the EU system for classifying economic activities. The value and quantity data shown for a product, therefore, includes not only the production by enterprises classified to the NACE sector where it is primarily produced but also its subsidiary production by enterprises classified to the other NACE Rev. 2 sectors.
Classification of Products The PRODCOM list is divided into “Classes” corresponding to the classes of NACE rev 2. Within the individual classes, the headings of the list are set out in ascending order of their PRODCOM codes. PRODCOM uses an eight-digit product code of the form XX.XX.XX.YY. The first four digits of the code correspond to the 4-digit classes of NACE Rev. 2. The first six digits are the Community Classification of Products by Activity (CPA) codes. The CPA provides a detailed listing of the characteristic products for each 4-digit NACE Rev. 2 economic activity. The last two digits provide a more detailed breakdown of the CPA classes into PRODCOM product headings. There is a direct link between the PRODCOM classification and the EU foreign trade Combined Nomenclature (CN). Each PRODCOM 8-digit heading covers one or more CN 8-digit headings.
Products from CPA sections B and C and class 38.32 are covered by the PRODCOM list.
National version of the classification National version of the classification of products is called CZ-PRODCOM list. The list is more detailed, corresponds to all industrial CPA classes, contains approximately 4400 headings.
Structure of a CZ-PRODCOM code is XXXXXYYZZ:
The six digits of the CZ-PRODCOM code, i.e. XXXXXX, in most cases correspond to the six-digit numerical code of the CZ-CPA classification. Thus it is possible to apply explanations to the CZ-CPA classification when classifying products.
XXXXXXYY is an eight-digit code corresponding to the European PRODCOM List. The seventh and eighth places in this code (YY) specify is more detailed item upon the CZ-CPA level.
XXXXXXYYZZ is the ten-digit code of the CZ-PRODCOM product list. The ninth place in this code is used for more detailed national breakdown. The tenth place has a technical character and is used to indicate the measurement unit - number 1 means that the product / service is surveyed only in value. Number 2 means that fot the product / service both value and volume are surveyed.
To view the national classification, please see this website.
3.3. Coverage - sector
The results cover both institutional sectors of non-financial corporations (S11) and households as entrepreneurs (S14.1 or 14.2).
3.4. Statistical concepts and definitions
The purpose of the statistics is to report, for each product in the PRODCOM List, how much industrial products and services has been produced in the reporting country during the reference period. This means that PRODCOM statistics relate to products (not to activities) and are therefore not strictly comparable with activity-based statistics such as Structural Business Statistics. The NACE codes on which PRODCOM codes are based merely serve to identify the enterprises that should be surveyed in order to determine the amount of production of the product.
The products: the PRODCOM List defines the products to be included in the survey. There are approximately 4.000 headings representing manufactured products and some industrial services.
The value and the volume of production: the value is expressed in national currency but where necessary converted to Euro by Eurostat. The volume is expressed in a unit specified for each product.
The volume/quantity unit: the measurement unit, such as kilograms, square metres etc. used to indicate the volume of goods produced.
Variables:
Actual production represents all production that was produced by the enterprise during the reference period, regardless of whether it was sold, stored in stocks, used for further processing or it was production under sub-contracted operations. Actual production is presented as quantity.
Total production sold is the production that was sold (invoiced) by the enterprise during the reference period. It does not matter whether this production was actually produced during the reference period (it could have been, for example, the sale of stock). It includes the production of own industrial products, industrial services, as well as production under sub-contracted operations. Production sold is presented as quantity and value.
Production sold includes production on own account and production of industrial services. Own production represents "traditional" industrial production. The enterprise is the owner of the input material, really produces the final product and sells it to the customer. Industrial service is an industrial production that does not create a new finished product defined in CZ-PRODCOM. These are only services leading to complete final products and ensuring its function: repairs and maintenance, installation and assembly, modifications and others. Production sold is presented as quantity and value.
Production under sub-contracted operations is a specific supplier-customer relationship, where the production company (processor) is not the owner of the input material or the completed finished product, but really produces it with its own employees and its own means of production. Value of the this production is equal to service provided, fee paid for the service, not to the value of the finished product. is presented as quantity and value (= fee paid).
Production is valued at basic current prices, which are invoiced by the manufacturer to the customer or forwarded to its own sales network. These prices do not include VAT, excise duty and customs duty; include a subsidy for the production or the service.
3.5. Statistical unit
Reporting and observation unit is Kind-of-activity Unit, as identified by national business register.

According to the national legislation, the access to the microdata is allowed for scientific purposes only. Each request is decided on individual basis by the relevant expert group.
10.5. Dissemination format - other
The data are regularly transmitted to Eurostat, please see this website.
10.6. Documentation on methodology
Important aspects and procedures of quality management within statistical production process as well as methodology are documented by the internal Statistical Metadata System (also in the form of so-called Technical projects), serving as instructions for surveyors (available for every produced statistics).
Technical projects in general contain description of the primary input data, data sources, definition of population, sampling procedure, processing technology, requirements for data transfer, control relations and checks, automatic corrections, derived indicators, definition of organization responsibilities, description of controls and relations, methodology of imputations, definition of outputs, description of input, source and user databases, backups, schedules of project and program preparation, schedules of preliminary and final processing, etc. In the CZSO there is a process of technical project preparation that is coordinated by the Department for Methodology of Performing Statistical Processing. For these purposes, every year the so-called Schedule of technical preparation of statistical surveys is discussed by the advisory bodies of the President, establishing the activities, the terms and the responsible units. Regarding the documetation accesible to the wide public, a methodology section is published on the CZSO website - Statistics of industrial goods and services (PRODCOM) - Methodology. Advanced information on methodology appears occasionally in specialised periodicals.
10.7. Quality management - documentation
The whole process of data production is driven by internal documentation (Technical project and the Statistical Metadata System), and this can be accessed by all interested parties (see the point 10.6).
"CZSO Quality Commitment" and "Quality policy of the CZSO" are part of the CZSO's Key Documents and are available on the CZSO website.
11.1. Quality assurance
The key components of the quality assurance are the following:
Strategic documents of the CZSO: Mission, Vision and Priorities of the CZSO, Quality commitment, Priority tasks defined for each year (please visit this website);
Irregular methodological audits represent an important tool in quality control. Audits are usually carried out by groups formed both by internal and external experts (NA experts, representatives of universities, ministries, etc);
Important aspects and procedures of quality management within statistical production process are documented by internal Statistical metadata system, including so-called Technical projects, eventually by instructions for surveyors (available for every produced statistics).
Punctuality and any errors in published data are systematically monitored. The main quality assurance activity for Prodcom is the data validation. Prodcom is published with a high level of detail, its accuracy therefore depends on data being checked in several ways.
11.2. Quality management - assessment
Industrial products statistics data are collected via electronic system. Questionnaire and collecting system provide a number of arithmetic and logical controls, both mandatory and optional between the items in each form and between the forms in the whole annual report. There are a number of arithmetic and logical controls inside the questionnaire. The questionnaire cannot be filled-in successfully before all errors inside the questionnaire, detected by the checking program, have been corrected.
12.1. Relevance - User Needs
The main users of PRODCOM data can be presented in different groups, namely:
EXTERNAL/ INTERNATIONAL (OUTSIDE NSI), like:
Institutions at European level: Eurostat;
Multi-national organizations: United Nations, FAO, ICAC, IFA.
EXTERNAL/ NATIONAL (OUTSIDE NSI), like:
Institutions at national level - governamental: Ministry of Industry and Trade;
Institutions at national level - non-governamental: Czech National Bank, Trade unions, Media, Researchers and students, Companies.
INTERNAL (INSIDE NSI), like: National accounts, Environmental statistics, SBS, ITGS, Agricultural and Forestry Statistics, Price statistics.
12.2. Relevance - User Satisfaction
No users satisfaction surveys are carried out exclusively for Industrial Products Statistics at the national level.
However, the CZSO is constantly in contact with different groups of users, e.g. Ministry of Industry and Trade, Czech National Bank, different associations, internal users etc. Formal meetings with users are organized regularly by the General Methodology Department.
12.3. Completeness
The CZSO provides Eurostat all the data requested by the EBS Regulation.
13.1. Accuracy - overall
Sampling error is not relevant (exhaustive survey).
The sample is taken from Business Register. In 2024, 8.113 units were included.
In 2024, the unit response rate (unweighted, number of enterprises) to the PRODCOM Survey was of 84,8 % of all the surveyed units. The issue of unit non-response is treated while collecting the questionnares (logical checks, contact with respondent), being covered by estimations.
Controls on the quality of the data:
Stage 1 – Questionnaires are collected and checked by the special office staff. Questionnaire and collecting system provide a number of arithmetic and logical controls. Staff is in close contact with the respondents. Cross-survey checks are also included.
Stage 2 – Central staff checks the preliminary results. Final results are approved and prepared for publication.
13.2. Sampling error
Sampling errors do not occur in the PRODCOM survey, as these statistics are collected by non-probability sampling (which means that it is a full coverage survey with a cut-off threshold).
13.3. Non-sampling error
The main types of non-sampling errors can be classified as follows:
measurement errors (wrong codes, different measurement unit);
data typing errors;
unit non-response;
coverage.
Unit non-response (unweighted, number of enterprises) in 2024 is at the level of approx. 15,2 % (small units), each non-respondent is contacted several times (and then estimated, if necessary). All the errors are treated, analysed, consulted with the respondent and corrected, if necessary.
Item non-response indicator is irrelevant for the CZ; the statistical questionary is designed so that the case of item non-response is it not allowed to occure.
Imputation rate (unweighted, number of enterprises) is 8,4 %.
In general, it can be distinguished between the following types of coverage error:
Undercoverage: there are target population units which are not accessible via the frame (e.g. enterprises carrying out “industrial activities” but not accessed by the survey);
Overcoverage: there are units accessible via the frame which does not belong to the target population (e.g. service enterprises classified and surveyed as “industrial” enterprises);
Multiple listings: target population units are present more than once in the frame (e.g. identical enterprises under different firm names and addressed listed twice in the SBR);
Incorrect auxiliary information: the auxiliary information provided by the frame may be inaccurate for some population units (e.g. wrong employment or turnover size of units in a business register).
Undercoverage
The following reasons for undercoverage are:
units with non-industrial prevailing activity but with secondary industrial activities;
units with less than 20 persons employed and low annual turnover.
The reason to exclude these units is to minimize or to avoid the respondent burden of small sized enterprises totally. To ensure sufficient level of coverage but non-inudstrial units with important share of industrial activities or important share of particular production and small units with important share of particular production are individually included.
Further reasons for undercoverage can be assumed in cases of
unit-non-response (where the estimate is not possible);
commodity classification errors.
Overcoverage
Overcoverage occurs as a result of misclassification in SBR and does not effect data quality. The unit from the sample without any industrial production is classified correctly and its data does not effect the Prodcom data.
Approximately 0,1 % of sample (weighted by annual turnover) is identified as overcoverage every year.
Multiple listings
No units are present more than once. Each unit is characterized by an unique identity number. In case of formal changes in structure of units, the data are treated to ensure that one production is not multiplied.
14.1. Timeliness
Preliminary data are trasmitted to Eurostat in June, 6 months following the end of reference period and they are published on the CZSO website in July, 7 months following the end of reference period in the electronic publication Production of Selected Industrial Products: Preliminary data in Eurostat structure, see the Catalogue of Products (No. 150206).
Industrial Products Statistics data are published on the CZSO website in November, 11 months following the end of reference period in the electronic publication Production of Selected Industrial Products, see the Catalogue of Products (No. 150140).
14.2. Punctuality
The statistics are published without delay in relation to the scheduled date.
15.1. Comparability - geographical
Not applicable at MS level. Statistics are comparable across the EU.
15.2. Comparability - over time
Time series of selected products or aggregates back to 1993 are published.
An extensive revision of NACE in 2007 has resulted in changes to PRODCOM estimates for the 2008 survey onwards.
Since the publication of the data 2021, comparable data for 3 last years in the currently valid CZ-PRODCOM codes are published.
Implementation of EBS Regulation Requirements did not caused significant incomparability over time. The main change lies in the consistent inclusion of production under sub-contracted operations into the presented volumes/values.
15.3. Coherence - cross domain
Cross-checks are made between SBS, ITGS and STS at micro and macro level. The cases with spotted differences are further analysed and, if necessary, corrected as well.
15.4. Coherence - internal
PRODCOM statistics is internally coherent. The same concepts and methods are used to collect, process, imput and validate all PRODCOM data. The Czech survey nomenclature CZPRODCOM is compatible with the PRODCOM List. The survey and validation checks ensure coherence between variables. Quantities, values of production and unit prices of products are also checked in y-o-y or long time-series comparison.
For 2024, the estimated number of working hours spent by 1 respondent to fill-in the questionnaire: 5 hrs, approx. 8 100 respondents are surveyed every year.
17.1. Data revision - policy
Data revisions follow the Revision Policy of the CZSO, which represents one of the key documents of the office (accessible via CZSO website in Czech & English)
Calendar of standard revisions is being prepared together with the release calendar.
17.2. Data revision - practice
After amandements in legal acts and detection of significant errors, the revisions of statistical idicators are performed. Users are informed immediately about these results and changes, as well as about the planned revisions.
At Y+ 6 months - the preliminary data are published (transmitted to Eurostat pursuant to Council Regulation (EEC) No. 3924/91 of 19 December 1991 on the establishment of a Community survey of industrial production).
At Y+ 7 months - the preliminary data are published on the CZSO website (dataset Production of Selected Industrial Products: Preliminary data in Eurostat structure).
At Y+ 11 months - more accurate data for the reference period are released (dataset Production of Selected Industrial Products is published).
At Y+ 2 years - 1st data revision (corrections performed on the basis of the processing of the next period data) is carried out; the data are then considered as final and are released together with the results for the period Y+1y.
Because of the survey nature, which offers a higher potential for misclassification, occasional revisions over the whole length of the time series can be carried out.
18.1. Source data
Type of data source: Statistical survey (Prum 2-01).
Frame on which the source is based: Business Register (RES).
Sample or census: The cut-off treshold.
Criteria for stratification: Characteristics used for stratification are the activity, number of employees and the turnover as registered by the VAT declaration.
Threshold values and percentages: The survey population is made up of all units with prevailing industrial activity (classified in NACE Rev. 2 sections B to E) with 20 or more employees or significant annual turnover or small industrial units with high importance within procuction a code, or non-industrial units with important share of industrial acitivites.
Frequency of updating the sample: Sample design is carried out once a year.

18.4. Data validation
The data validation is driven by survey documentation (Technical project, SMS Ulohy), which describes approx. 80 validation checks attributed to the processing of the questionnaire Prum 2-01. This contains:
Validity of each attribute collected within the questionnaire (e.g. enterprise's ID, NACE, etc.);
Logical checks between indicators inside the questionnaire;
Comparison over time (previous year);
Cross-survey checks (STS, SBS);
Comparison between enterprises belonging to the same category.
Feedback from the validation on micro level is available also to reporting units in case of electronic data collection (electronic questionnaire, online data collection).
18.5. Data compilation
Data processing
When the survey population is selected from the Business Register, a detailed analysis is carried out by the staff dealing with the new "births" or reorganisations and, if there are issues detected, these are fed back to Business Register.
At level of the Regional Statistical Office:
receive the questionnaires;
data recording into a local database;
running of the IT tools for detecting the errors; data are corrected where necessary
contacts with respondents.
At Central Statistical Office, the folowing actions are taking place:
data validation from the macro level, and where necessary the enterprises are contacted through the Regional Statistical Offices
non-response treatment.
Estimates for non-response
Not responding units are imputed. Estimation for non-response is based on the results of the unit responded in previous period(s) or related enterprises. The estimate is based on STS and SBS data.

No comment.
The PRODCOM survey provides information on industrial goods and services PRODuction of the European COMmunity in compliance with Regulation (EU) 2019/2152 of 27 November 2019 on European business statistics. The Czech Statistical Office is responsible for compilation of these statistics in the Czech Republic.
PRODCOM data are collected via survey 'Annual questionnaire on industry'.
19 December 2025
The purpose of the statistics is to report, for each product in the PRODCOM List, how much industrial products and services has been produced in the reporting country during the reference period. This means that PRODCOM statistics relate to products (not to activities) and are therefore not strictly comparable with activity-based statistics such as Structural Business Statistics. The NACE codes on which PRODCOM codes are based merely serve to identify the enterprises that should be surveyed in order to determine the amount of production of the product.
The products: the PRODCOM List defines the products to be included in the survey. There are approximately 4.000 headings representing manufactured products and some industrial services.
The value and the volume of production: the value is expressed in national currency but where necessary converted to Euro by Eurostat. The volume is expressed in a unit specified for each product.
The volume/quantity unit: the measurement unit, such as kilograms, square metres etc. used to indicate the volume of goods produced.
